s DIFFERENCES AMONG PRODUCTS
Memory size In evaluation with an evaluation product, note the difference between the evaluation product and the product actually used. The following items must be taken into consideration. * The MB90V370 does not have an internal ROM, however, operations equivalent to chips with an internal ROM can be evaluated by using a dedicated development tool, enabling selection of ROM size by settings of the development tool. * In the MB90V370, images from FF4000H to FFFFFFH are mapped to bank 00, and FF0000H to FF3FFFH are mapped to bank FF only. (This setting can be changed by the development tool configuration.) * In the MB90372/F372, images from FF4000H to FFFFFFH are mapped to bank 00, and FF0000H to FF3FFFH are mapped to bank FF only.

s HANDLING DEVICES
* Be sure that the maximum rated voltage is not exceeded (latch-up prevention) . A latch-up may occur on a CMOS IC if a voltage higher than VCC or lower than VSS is applied to an input or output pin other than medium-to-high voltage pins. A latch-up may also occur if a voltage higher than the rating is applied between VCC and VSS. A latch-up causes a rapid increase in the power supply current, which can result in thermal damage to an element. Take utmost care that the maximum rated voltage is not exceeded. When turning the power on or off to analog circuits, be sure that the analog supply voltages (AVCC, CVCC, AVR, CVRH1, CVRH2 and CVRL) and analog input voltage do not exceed the digital supply voltage (VCC) . * Stabilize the supply voltages Even within the operation guarantee range of the VCC supply voltage, a malfunction can be caused if the supply voltage undergoes a rapid change. For voltage stabilization guidelines, the VCC ripple fluctuations (P-P value) at commercial frequencies (50 Hz to 60 Hz) should be suppressed to 10% or less of the reference VCC value. During a momentary change such as when switching a supply voltage, voltage fluctuations should also be suppressed so that the transient fluctuation rate is 0.1 V/ms or less. * Power-on To prevent a malfunction in the built-in voltage drop circuit, secure 50 s (between 0.2 V and 1.8 V) or more for the voltage rise time during power-on. * Treatment of unused input pins An unused input pin may cause a malfunction if it is left open. Every unused input pin should be pulled up or down. * Treatment of A/D converter, D/A converter and comparator power pin When the A/D converter, D/A converter and comparator is not used, connect the pins as follows : AVCC = CVCC = VCC, AVSS = AVR = CVSS = CVRL = CVRH1 = CVRH2 = VSS. * Notes on external clock When an external clock is used, the oscillation stabilization wait time is required at power-on reset or at cancellation of sub-clock mode or stop mode. As shown in diagram below, when an external clock is used, connect only the X0 pin and leave the X1 pin open.
X0 MB90370/375 series Open X1
* Power supply pins When a device has two or more VCC or VSS pins, the pins that should have equal potential are connected within the device in order to prevent a latch-up or other malfunction. To reduce extraneous emission, to prevent a malfunction of the strobe signal due to an increase in the group level, and to maintain the local output current rating, connect all these power supply pins to an external power supply and ground them. The current source should be connected to the VCC and VSS pins of the device with minimum impedance. It is recommended that a bypass capacitor of about 0.1 F be connected near the terminals between VCC and VSS. 19
MB90370/375 Series
* Analog power-on sequence of A/D converter, D/A converter and comparator The power to the A/D converter, D/A converter and comparator (AVCC, CVCC, AVR, CVRH1, CVRH2 and CVRL) and analog inputs (AN0 to AN11, VOL1 to VOL3, VSI1 to VSI3, SW1 to SW3, DCIN and DCIN2) must be turned on after the power to the digital circuits (VCC) is turned on. When turning off the power, turn off the power to the digital circuits (VCC) after turning off the power to the A/D converter, D/A converter, comparator and analog inputs. When the power is turned on or off, AVR should not exceed AVCC. And CVRH1, CVRH2 and CVRL should not exceed CVCC. Also, when a pin that is used for A/D analog input is used as an input port, the input voltage should not exceed AVCC. And when comparator analog input is also used as an input port, the input voltage should not exceed CVCC. (The power to the analog circuits and the power to the digital circuits can be simultaneously turned on or off.) * Caution on Operations during PLL Clock Mode If the PLL clock mode is selected, the microcontroller attempt to be working with the self-oscillating circuit even when there is no external oscillator or external clock input is stopped. Performance of this operation, however, cannot be guaranteed.

* : The MB90V370 does not contain ROM. Assume that the development tool uses these area for its ROM decode areas. Note : ROM data in the FF bank can be seen as an image in the higher 00 bank to validate the small model C compiler. Because addresses of the 16 low-order bits in the FF bank are the same, the table in ROM can be referenced without the "far" specification. For example, when 00C000H is accessed, the contents of ROM at FFC000H are actually accessed. The ROM area in the FF bank exceeds 48 kilobytes, and all areas cannot be seen as images in the 00 bank. Because ROM data from FF4000H to FFFFFFH is seen as an image at 004000H to 00FFFFH, the ROM data table should be stored in the area from FF4000H to FFFFFFH.

And if EI2OS clear is supported, both interrupt request flags for the two interrupt causes are cleared by EI2OS interrupt clear signal. It is recommended to mask either of the interrupt request during the use of EI2OS. * EI2OS service cannot be started multiple times simultaneously. Interrupt other than the operating interrupt is masked during EI2OS operation.

s PERIPHERAL RESOURCES
1. Low-power Consumption Control Circuit
The MB90370/375 series has the following CPU operating mode selected by the configuration of an operating clock and clock operation control. * Clock Mode * PLL clock mode In this mode, a PLL clock that is a multiple of the oscillation clock (HCLK) is used to operate the CPU and peripheral functions. * Main clock mode In this mode, the main clock, with the oscillation clock (HCLK) frequency divided by 2 is used to operate the CPU and peripheral functions. In the main clock mode, the PLL multiplier circuit is inactive. * Sub-clock mode In this mode, the sub-clock, with the sub-clock (SCLK) frequency divided by 4 is used to operate the CPU and peripheral functions. In the sub-clock mode, the main clock and PLL multiplier circuit are inactive. * CPU Intermittent Operating Mode In this mode, the CPU is operated intermittently while high-speed clock pluses are supplied to peripheral functions, thereby reducing power consumption. In this mode, intermittent clock pulses are supplied only to the CPU while it is accessing a register, internal memory, or peripheral function. * Standby Mode In this mode, the low-power consumption control circuit stops supplying the clock to the CPU (sleep mode) or the CPU and peripheral functions (timebase timer mode) or stops the oscillation clock itself (stop mode) , thereby reducing power consumption. * PLL sleep mode The PLL sleep mode is activated to stop the CPU operating clock in the PLL clock mode. Components excluding the CPU operate on the PLL clock. * Main sleep mode The main sleep mode is activated to stop the CPU operating clock in the main clock mode. Components excluding the CPU operate on the main clock. * Sub-sleep mode The sub-sleep mode is activated to stop the CPU operating clock in the sub-clock mode. Components excluding the CPU operate on the divided-by-four sub-clock. * Timebase timer mode The timebase timer mode causes the operation of functions, excluding the oscillation clock, timebase timer, and watch timer, to stop. All functions other than the timebase timer and watch timer are inactivated. * Watch mode and main watch mode The watch mode and main watch mode operates the watch timer only. The sub-clock operates but the main clock and PLL multiplier circuit stop. * Stop mode The stop mode causes the oscillation to stop. All functions are inactivated. Note : Because the stop mode turns the oscillation clock off, data can be retained by the lowest power consumption.

2. I/O Ports
(1) Outline of I/O ports Each I/O port outputs data from the CPU to the I/O pins or inputs signals from the I/O pins to the CPU as directed by the port data register (PDR) . Each CMOS I/O port can also designate the direction of a data flow (input or output) at the I/O pins in bit units using the port data direction register (DDR) . Or N-channel open-drain port can designate the direction of a data flow (input or output) at the I/O pins in bit units using the port data register (PDR) .

8. I2C
The I2C (Inter IC Bus) interface is a simple structure bidirectional bus consisting of two wires : a serial data line (SDA) and a serial clock line (SCL) . Among the devices connected with these two wires, information is transmitted to one another. By recognizing the unique address of each device, it can operate as a transmitting or receiving device in accordance with the function of each device. Among these devices, the master/slave relation is established. The I2C interface can connect two or more devices to the bus provided the upper limit of the bus capacitance does not exceed 400 pF. It is a full-fledged multi-master bus equipped with collision detection and communication adjustment procedures designed to avoid the destruction of data if two or more masters attempt to start data transfer simultaneously. The communication adjustment procedure permits only one master to control the bus when two or more masters attempt to control the bus so that messages are not lost or the contents of messages are not changed. Multimaster means that multiple masters attempt to control the bus simultaneously without losing messages. This I2C interface includes MCU standby mode wake-up function, and a CRC-8 calculator that performs automatic Packet Error Code (PEC) generation and verification.

9. MI2C
The Multi-address I2C (Inter IC Bus) interface is a simple structure bidirectional bus consisting of two wires : a serial data line (SDA) and a serial clock line (SCL) . Among the devices connected with these two wires, information is transmitted to one another. By recognizing the unique address of each device, it can operate as a transmitting or receiving device in accordance with the function of each device. Among these devices, the master/slave relation is established. The Multi-address I2C interface can connect two or more devices to the bus provided the upper limit of the bus capacitance does not exceed 400 pF. It is a full-fledged multi-master bus equipped with collision detection and communication adjustment procedures designed to avoid the destruction of data if two or more masters attempt to start data transfer simultaneously. This macro provides 6 addresses to implement the multi-address function. The communication adjustment procedure permits only one master to control the bus when two or more masters attempt to control the bus so that messages are not lost or the contents of messages are not changed. Multimaster means that multiple masters attempt to control the bus simultaneously without losing messages. This Multi-address I2C interface includes MCU standby mode wake-up function, and a CRC-8 calculator that performs automatic Packet Error Code (PEC) generation and verification.

11. Comparator
This comparator circuit monitors voltage of up to three batteries and automatically controls electric discharge. Either parallel discharge or sequential discharge can be selected. * Parallel discharge control In parallel discharge control, all batteries are allowed to discharge when power is not being supplied from the AC adapter. * If power is being supplied from the AC adapter, the permission/prohibition of discharge for batteries is controlled by software. * Sequential discharge control In sequential discharge control, the comparator controls discharge in a specified order, while monitoring intermittent interruption of power, voltage level, and mount/dismount of batteries, when power is not being supplied from the AC adapter. * If power is being supplied from the AC adapter, the permission/prohibition of discharge for batteries is controlled by software. * Up to three batteries can be controlled, and the order of discharge can be selected. * The affect of intermittent interruption of power is automatically filtered. * Mount/dismount of batteries is automatically detected and discharge is controlled. * Battery voltage is monitored, and if battery voltage is below the specified voltage, a change over to the next battery is automatically done.

14. A/D converter
The A/D (Analog to Digital) converter converts the analog voltage input to an analog input pin (input voltage) to a digital value. The converter has the following features : * The minimum conversion time is 6.13 s (for a machine clock of 16 MHz; includes the sampling time) . * The minimum sampling time is 3.75 s (for a machine clock of 16 MHz) . * The converter uses the RC-type successive approximation conversion method with a sample and hold circuit. * A resolution of 10 bits or 8 bits can be selected. * Up to twelve channels for analog input pins can be selected by a program. * Various conversion modes : - Single conversion mode : Selectively convert one channel. - Scan conversion mode : Continuously convert multiple channels. Maximum of 12 selectable channels. - Continuous conversion mode : Repeatedly convert specified channels. - Stop conversion mode : Convert one channel then halt until the next activation. (Enables synchronization of the conversion start timing.) * At the end of A/D conversion, an interrupt request can be generated and EIOS can be activated. * In the interrupt-enabled state, the conversion data protection function prevents any part of the data from being lost through continuous conversion. * The conversion can be activated by software, 16-bit reload timer 4 (rise edge) and ADTG.

15. D/A converter
The D/A (Digital to Analog) converter is used to generate an analog output from an 8-bit digital input. By setting the enable bit in the D/A control register (DACR) to 1, it will enable the corresponding D/A output channel. Hence, setting this bit to 0 will disable that channel. If D/A output is disabled, the analog switch inserted to the output of each D/A converter channel in series is turned off. In the D/A converter, the bit is cleared to 0 and the direct-current path is shut off. The above is also true in the stop mode. The output voltage of the D/A converter ranges from 0 V to 255/256 x AVCC. The D/A converter output does not have the internal buffer amplifier. The analog switch ( = 100 ) is inserted to the output in series. To apply load to the output externally, estimate a sufficient stabilization time. Table below lists the theoretical values of output voltage of the D/A converter. Value written to DA07 to DA00 and DA17 to DA10 Theoretical value of output voltage 00H 01H 02H : FDH FEH FFH 0/256 x AVCC ( = 0 V) 1/256 x AVCC 2/256 x AVCC : 253/256 x AVCC 254/256 x AVCC 255/256 x AVCC

16. LPC interface
The LPC (Low Pin Count) interface consists of an LPC bus interface, universal parallel interface (UPI x 4 channels) , gate address A20 function and LPC data buffer array. By using the LPC bus interface and UPI, data can be exchanged with an external host CPU synchronously via an external LPC bus. * LPC bus interface The LPC bus interface provides direct access of host CPU to UPI. * It supports I/O read and I/O write cycle only. Other cycle types will be ignored. * It supports LPC clock running at 33 MHz. * Universal parallel interface, UPI x 4 channels The UPI is used to exchange parallel data to serial data in LPC bus with host CPU. * An 8-bit data will be transmitted or received. * A buffer function is available for independent input and output. * The I/O buffer status can be output externally through LPC bus interface. * Gate address A20 function for UPI channel 0 The GA20 (Gate Address A20) is intended to implement the memory management in a PC architecture. This allows the access to the extended memory needed by the operating system. On-chip logic is provided to speed up the generation of GA20. * Data buffer array The data buffer array is consisted of 32 bytes UP data register and 16 bytes DOWN data register to speed up the data transfer between MCU and external host through LPC bus.

17. Serial IRQ controller
The serial IRQ controller consists of a 6-channel serial IRQ control circuit and an LPC clock monitor / control circuit. By using this serial IRQ controller, host interrupt requests can be transferred serially through a single signal wire (SERIRQ) , synchronized with the LPC clock. 6-channel serial IRQ control circuit * The 6-channel serial IRQ control circuit consists of a serial interrupt control register (SICR) , 4 serial interrupt frame number registers (SIFR1 to SIFR4) , a protocol state machine and a serial interrupt data latch and output control. * For channel 0A, 0B and 1 to 3, if SICR : OBE bit (OBF controlled enable bit) = 0, then serial IRQ can be controlled by software setting of SICR : IRR bit. If SICR : OBE bit = 1, then software control is disabled and serial IRQ is controlled by OBF flag (Output buffer full flag) from LPC UPI0 to UPI3. * For channel 4, serial IRQ can be controlled by software setting of SICR : IRR bit. * For channel 0A and 0B, additional enable bit (SICR : EN0A/0B bit) can be used to latch and keep the OBF0 or IRR0A/0B bit status. * The serial interrupt data latch transfers serial IRQs serially according to their frame number. The frame number for channel 0A is fixed to "IRQ1", for channel 0B is fixed to "IRQ12", and the frame number for channel 1 to channel 4 are software programmable (IRQ1 to IRQ15, and IRQ21 to IRQ31) by setting the SIFR1 to SIFR4. * By monitoring the SERIRQ and the LPC clock pin, the protocol state machine can detect the START frame condition. Then it starts counting the DATA frame and transfers its serial IRQs through SERIRQ. Finally it can switch to continuous/quiet mode operation by determine the STOP frame condition. * The serial interrupt output control support both continuous and quiet mode operation. In continuous mode operation, only the host can initiate the serial IRQs transfer; In quiet mode operation, both the host and slave (e.g. the serial IRQ controller) can initiate the serial IRQs transfer. LPC clock monitor / control circuit * The LPC clock monitor / control circuit consists of a clock-run monitor / control circuit. By monitoring the clockrun pin (CLKRUN) , the clock monitor / control circuit can determine whether the host has stopped LPC clock in quiet mode operation or not. If LPC clock is stopped and the controller wants to initiate the serial IRQs transfer, then it can request the host to restart the LPC clock by controlling the CLKRUN pin.

19. Parity generator
The parity generator is a simple circuit that generates odd / even parity based on the input data. It consists of a parity generator data register (PGDR) , an odd / even parity generation logic and a parity generator control status register (PGCSR) . An 8-bit data can be loaded into PGDR, then the parity generator will generate odd / even parity based on the input data. Either odd or even parity can be generated by setting the PGCSR. For odd parity generation, if the number of "1"s in the PGDR is even number, then the parity bit in PGCSR will be set to "1", otherwise the parity bit will be set to "0". For even parity generation, if the number of "1"s in the PGDR is even number, then the parity bit in PGCSR will be set to "0", otherwise the parity bit will be set to "1". Table shows some examples of odd / even parity generation.

24. ROM correction function
When an address matches the value set in the address detection register, the instruction code to be loaded into the CPU is forced to be replaced with the INT9 instruction code (01H) . When executing a set instruction, the CPU executes the INT9 instruction. The ROM correction function is implemented by processing using the INT9 interrupt routine. The device contains two address detection registers, each provided with a compare enable bit. When the value set in the address detection register matches an address and the interrupt enable bit is "1", the instruction code to be loaded into the CPU is forced to be replaced with the INT9 instruction code.

26. 512K bit flash memory
The 512K bit flash memory is allocated in the FFH banks on the CPU memory map. Like masked ROM, flash memory is read-accessible and program-accessible to the CPU using the flash memory interface circuit. The flash memory can be programmed/erased by the instruction from the CPU via the flash memory interface circuit. The flash memory can therefore be reprogrammed (updated) while still on the circuit board under integrated CPU control, allowing program code and data to be improved efficiently. Note that sector operations such as "enable sector protect" cannot be used. Features of 512K bit flash memory : * 64 Kwords x 8 bits / 32 Kwords x 16 bits (16 K + 8 K + 8 K + 32 K) sector configuration * Automatic program algorithm (same as the Embedded Algorithm* : MBM29F400TA) * Installation of the deletion temporary stop/delete restart function * Write/delete completion detected by the data polling or toggle bit * Write/delete completion detected by the CPU interrupt * Compatibility with the JEDEC standard-type command * Each sector deletion can be executed (Sectors can be freely combined) . * Number of write/delete operations 10,000 times guaranteed * : Embedded Algorithm is a trademark of Advanced Micro Devices, Inc.

*1 : Set AVCC, CVCC and VCC at the same voltage. Take care so that AVR, CVRH1, CVRH2 and CVRL do not exceed VCC + 0.3 V when the power is turned on. *2 : VI and VO shall never exceed VCC + 0.3 V. VI should not exceed the specified ratings. However if the maximum current to/from an input is limited by some means with external components, the ICLAMP rating supersedes the VI rating. *3 : The maximum output current is a peak value for a corresponding pin. *4 : Applicable to pins : P00 to P07, P10 to P17, P20 to P27, P30 to P37, P47, P50 to P57, P60 to P67, P70 to P77, PA0 to PA6, PC3 to PC7, PD0 to PD3, PD6, PD7 Use within recommended operating conditions. Use at DC voltage (current) . The +B signal should always be applied a limiting resistance placed between the +B signal and the microcontroller. The value of the limiting resistance should be set so that when the +B signal is applied the input current to the microcontroller pin does not exceed rated values, either instantaneously or for prolonged periods. Note that when the microcontroller drive current is low, such as in the power saving modes, the +B input potential may pass through the protective diode and increase the potential at the Vcc pin, and this may affect other devices. Note that if a +B signal is input when the microcontroller power supply is off (not fixed at 0V) , the power supply is provided from the pins, so that incomplete operation may result. Note that if the +B input is applied during power-on, the power supply is provided from the pins and the resulting supply voltage may not be sufficient to operate the power-on reset. Care must be taken not to leave the +B input pin open. Note that analog system input/output pins other than the A/D input pins (LCD drive pins, comparator input pins, etc.) cannot accept +B signal input.

6. A/D Converter Glossary
Analog changes that are identifiable with the A/D converter. The deviation of the straight line connecting the zero transition point ("00 0000 0000" "00 0000 0001") with the full-scale transition point ("11 1111 1110" "11 1111 1111") from actual conversion characteristics. Differential linearity error : The deviation of input voltage needed to change the output code by 1 LSB from the theoretical value. Total error : The total error is defined as a difference between the actual value and the theoretical value, which includes zero-transition error/full-scale transition error and linearity error. Resolution : Linearity error :

7. Notes on Using A/D Converter
Select the output impedance value for the external circuit of analog input according to the following conditions. Output impedance values of the external circuit of 4 k or lower are recommended. When capacitors are connected to external pins, the capacitance of several thousand times the internal capacitor value is recommended to minimized the effect of voltage distribution between the external capacitor and internal capacitor. When the output impedance of the external circuit is too high, the sampling period for analog voltages may not be sufficient. * Equipment of analog input circuit model
Sampling and hold circuit Analog input Comparator R C
R : about 1.9 k C : about 32.3 pF Note : Listed values must be considered as standards.
* Error The smaller the | AVR - AVSS | is, the greater the error would become relatively.
