4-Bit Microcontroller with Built-in RC Oscillation Type A/D Converter and LCD Driver
GENERAL DESCRIPTION
The MSM64162A is a low power 4-bit microcontroller that employs Oki's original CPU core nX4/20. The MSM64162A has 2-channel RC oscillation type A/D converter, LCD driver for up to 80 segments, and buzzer output port. It is best suited for applications such as low power, high precision thermometers and hygrometers.

Program Memory Map Address 000H is the instruction execution start address by the system reset. The CZP area from address 010H to address 01FH is the start address for the CZP subroutine of 1-byte call instruction. The start address of interrupt subroutine is assigned to the interrupt address from address 020H to 03DH. The user area has 2016 bytes of address 000H to address 07DFH. No program can be stored in the test program area.

Data Memory Map The data RAM area (128 nibbles) is shared by the stack area. The stack is a memory starting from address 7FFH toward the low-order addresses where 4 nibbles are used by Subroutine Call Instruction and 8 nibbles are used by an interrupt. The addresses 080H to 0FFH of BANK 0 and the addresses 700H to 77FH of BANK 7 are not assigned as the data memory, so access to these addresses has no effect. Moreover, it is impossible to access BANK 1 to BANK 6.

MSM64162A
FUNCTIONAL DESCRIPTION
* A/D converter (ADC) The MSM64162A has a built-in 2-channel RC oscillation type A/D converter. The A/D converter is composed of a 2-channel oscillation circuit, Counter A (CNTA0-4, a 4.8-digit decade counter), Counter B (CNTB0-3, a 14-bit binary counter), and A/D Converter Control Registers 0 and 1 (ADCON0, ADCON1). By counting oscillation frequencies that vary depending on a resistor or capacitor connected to the RC oscillation circuit, the A/D converter converts resistance values or capacitance values to corresponding digital values. By using a thermistor or humidity sensor as a resistance, a thermometer or a hygrometer can be constructed. By applying a separate sensor to each channel of the 2-channel RC oscillation circuit, it is also possible to extend measure ranges or measure at two places. * LCD driver (LCD) The MSM64162A has a built-in LCD driver for 24 outputs. The LCD driver consists of 21 4-bit display registers (DSPR0-20), the Display Control Register (DSPCON), a 24-output LCD driver circuit, and a bias generation circuit (BIAS). The bias generation circuit for LCD driver (BIAS) generates bias voltages for the LCD driver by rising or dropping the power supply voltage by externally installing capacitors. Alternatively, it generates bias voltages by rising the constant voltage (VSS1 = -1.2 V) generated by the voltage regulator for LCD driver. Which way is to be used is specified by mask option. There are three types of driving methods: 1/4 duty, 1/3 duty and 1/2 duty. Software selects the duty mode. A mask option can select either a common driver or a segment driver for each LCD driver pin. A mask option can also specify assignment of each bit of the display register to each segment. All the display registers must be selected by a mask option. L16 to L23 of the LCD driver can be configured to be output ports by a mask option. The relationship between the duty, the bias method, and the maximum segment number follows: 1/4 duty 1/3 bias method ------- 80 segments 1/3 duty 1/3 bias method ------- 63 segments 1/2 duty 1/2 bias method ------- 44 segments * Buzzer driver (BD) The MSM64162A has a built-in buzzer driver with 2 buzzer output frequencies and 4 buzzer output modes. Each buzzer output is selected by the Buzzer Control Register (BDCON) and the Buzzer Frequency Control Register (BFCON). * Capture circuit (CAPR) The MSM64162A captures 32 Hz to 256 Hz output of the time base counter at the falling of Port 0.0 or 0.1 (P0.0 or P0.1) to "L" level when the pull-up resistor input is chosen, or at the rising to "H" level when the pull-down resistor input is chosen. The capture circuit is composed of the Capture Control Register (CAPCON) and the Capture Registers (CAPR0, CAPR1) that fetch output from the time base counter. * Watchdog timer (WDT) The MSM64162A has a built-in watchdog timer to detect CPU malfunction. The watchdog timer is composed of a 6-bit watchdog timer counter (WDTC) to count a 16 Hz output and a watchdog timer control register (WDTCON) to reset WDTC.

* Clock generation circuit (2CLK) The clock generation circuit (2CLK) in the MSM64162A contains a 32.768 kHz crystal oscillation circuit, a 400 kHz RC oscillation circuit, and a clock control port. This circuit generates the system clock (CLK) and the time base clock (32.768 kHz). The system clock drives the CPU while the time base clock drives the time base counter and the buzzer driver. Via the contents of the frequency Control Register (FCON), the system clock can be switched between 32.768 kHz (the output of the crystal oscillation circuit) and 400 kHz (the output of the RC oscillation circuit). Note: The oscillation frequency of the RC oscillation circuit varies depending on the value of an external resistor (ROS), operating power supply voltage (VDD), and ambient temperatures (Ta). * Time base counter (TBC) The MSM64162A has a built-in time base counter (TBC) that generates clocks to be supplied to internal peripheral circuits. The time base counter is composed of 15 binary counters. The count clock of the time base is driven by the oscillation clock (32.768 kHz) of the crystal oscillation circuit. The output of the time base counter is used for the buzzer driver, the system reset circuit, the watchdog timer, the time base interrupt, the sampling clocks of each port, and the capture circuit. * I/O port Input-output ports (P2, P3) (8 bits)
Input port (P0) (4 bits) Output port (P1) (4 bits)
: Pull-up (pull-down) resistor input or highimpedance input, CMOS output or NMOS open drain output: these can be specified for each bit; external 0 interrupt : Pull-up (pull-down) resistor input or highimpedance input; external 1 interrupt : CMOS output or NMOS open drain output
* Interrupt (INTC) The MSM64162A has 9 interrupt sources (9 vector addresses), of which two are external interrupts from ports and seven are internal interrupts. Of the nine interrupt sources, only the watchdog interrupt cannot be disabled (non-maskable interrupt). The other eight interrupts are controlled by the master interrupt enable flag (MI) and the interrupt enable registers (IE0, IE1 and IE2). When an interrupt condition is met, the CPU branches to a vector address corresponding to the interrupt source. * Battery check circuit (BC) The battery check circuit (BC) detects the level of the supply voltage by comparing the voltage generated by an external supply-voltage dividing resistor (RBLD) with the internal reference voltage (Vrb).

Notes for Mounting the Surface Mount Type Package The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).
