80C528/83C528
DESCRIPTION
The 8XC528 single-chip 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The 8XC528 has the same instruction set as the 80C51. Three versions of the derivative exist: ROM
multi-source, two-priority-level, nested interrupt structure, two serial interfaces (UART and I2C-bus), and on-chip oscillator and timing circuits. In addition, the 8XC528 has two software selectable modes of power reduction -- idle mode and power-down mode. The idle mode freezes the CPU while allowing the RAM, timers, serial port, and interrupt system to continue functioning. The power-down mode saves the RAM contents but freezes the oscillator, causing all other chip functions to be inoperative.

PIN DESCRIPTION
PIN NO. MNEMONIC VSS VDD P0.0-0.7 DIP 20 40 39-32 SDIL 21 42 41-34 LCC 22 44 43-36 QFP 16 38 37-30 TYPE I I I/O NAME AND FUNCTION Ground: circuit ground potential. Power Supply: +5V power supply pin during normal operation, Idle mode and Power-down mode. Port 0: Port 0 is an open-drain, bidirectional I/O port. Port 0 pins that have 1s written to them float and can be used as high-impedance inputs. Port 0 is also the multiplexed low-order address and data bus during accesses to external program and data memory. In this application, it uses strong internal pull-ups when emitting 1s. Port 1: Port 1 is an 8-bit bidirectional I/O port with internal pull-ups, except P1.6 and P1.7 which have open drain. Port 1 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 1 pins that are externally pulled low will source current because of the internal pull-ups. (See DC Electrical Characteristics: IIL). Port 1 can sink/source one TTL (4 LSTTL) inputs. T2 (P1.0): Timer/counter 2 external count input (following edge triggered). T2EX (P1.1): Timer/counter 2 trigger input. SCL (P1.6): I2C serial port clock line. SDA (P1.7): I2C serial port data line. Port 2: Port 2 is an 8-bit bidirectional I/O port with internal pull-ups. Port 2 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 2 pins that are externally being pulled low will source current because of the internal pull-ups. (See DC Electrical Characteristics: IIL). Port 2 emits the high-order address byte during fetches from external program memory and during accesses to external data memory that use 16-bit addresses (MOVX @DPTR). In this application, it uses strong internal pull-ups when emitting 1s. During accesses to external data memory that use 8-bit addresses (MOV @Ri), port 2 emits the contents of the P2 special function register. Port 3: Port 3 is an 8-bit bidirectional I/O port with internal pull-ups. Port 3 pins that have 1s written to them are pulled high by the internal pull-ups and can be used as inputs. As inputs, port 3 pins that are externally being pulled low will source current because of the pull-ups. (See DC Electrical Characteristics: IIL). Port 3 also serves the special features of the SC80C51 family, as listed below: RxD (P3.0): Serial input port TxD (P3.1): Serial output port INT0 (P3.2): External interrupt INT1 (P3.3): External interrupt T0 (P3.4): Timer 0 external input T1 (P3.5): Timer 1 external input WR (P3.6): External data memory write strobe RD (P3.7): External data memory read strobe Reset: A high on this pin for two machine cycles while the oscillator is running, resets the device. An internal diffused resistor to VSS permits a power-on reset using only an external capacitor to VDD. After a watchdog timer overflow, this pin is pulled high while the internal reset signal is active. Address Latch Enable: Output pulse for latching the low byte of the address during an access to external memory. In normal operation, ALE is emitted at a constant rate of 1/6 the oscillator frequency, and can be used for external timing or clocking. Note that one ALE pulse is skipped during each access to external data memory. Program Store Enable: The read strobe to external program memory. When the device is executing code from the external program memory, PSEN is activated twice each machine cycle, except that two PSEN activations are skipped during each access to external data memory. PSEN is not activated during fetches from internal program memory. External Access Enable: EA must be externally held low during RESET to enable the device to fetch code from external program memory locations 0000H to 7FFFH. If EA is held high during RESET, the device executes from internal program memory unless the program counter contains an address greater than 7FFFH. EA is don't care after RESET. Crystal 1: Input to the inverting oscillator amplifier and input to the internal clock generator circuits. Crystal 2: Output from the inverting oscillator amplifier.

ROM CODE PROTECTION
By setting a mask programmable security bit, the ROM content in the 83C528 is protected, i.e., it cannot be read out by any test mode or by any instruction in the external program memory space. The MOVC instructions are the only ones which have access to program code in the internal or external program memory. The EA input is latched during RESET and is `don't care' after RESET (also if security bit is not set). This implementation prevents reading from internal program code by switching from external program memory to internal program memory during MOVC instruction or an instruction that handles immediate data. Table 2 lists the access to the internal and external program memory by the MOVC instructions when the security bit has been set to logical one. If the security bit has been set to a logical 0 there are no restrictions for the MOVC instructions.
TIMER 2
Timer 2 is functionally equal to the Timer 2 of the 8052AH. Timer 2 is a 16-bit timer/counter. These 16 bits are formed by two special function registers TL2 and TH2. Another pair of special function register RCAP2L and RCAP2H form a 16-bit capture register or a 16-bit reload register. Like Timer 0 and 1, it can operate either as a timer or as an event counter. This is selected by bit C/T2N in the special function register T2CON. It has three operating modes: capture, autoload, and baud rate generator mode which are selected by bits in T2CON.
program has to reload the watchdog timer within periods that are shorter than the programmed watchdog timer internal. This time interval is determined by an 8-bit value that has to be loaded in register T3 while at the same time the prescaler is cleared by hardware. Watchdog timer interval = [256 * (T3)] 2048 on * chip oscillator frequency
BIT-LEVEL I2C INTERFACE
This bit-level serial I/O interface supports the I2C-bus. P1.6/SCL and P1.7/SDA are the serial I/O pins. These two pins meet the I2C specification concerning the input levels and output drive capability. Consequently, these pins have an open drain output configuration. All the four modes of the I2C-bus are supported: - master transmitter - master receiver - slave transmitter - slave receiver The advantages of the bit-level I2C hardware compared with a full software I2C implementation are: - the hardware can generate the SCL pulse - Testing a single bit (RBF respectively, WBF) is sufficient as a check for error free transmission. The bit-level I2C hardware operates on serial bit level and performs the following functions: - filtering the incoming serial data and clock signals - recognizing the START condition - generating a serial interrupt request SI after reception of a START condition and the first falling edge of the serial clock - recognizing the STOP condition - recognizing a serial clock pulse on the SCL line - latching a serial bit on the SDA line (SDI) - stretching the SCL LOW period of the serial clock to suspend the transfer of the next serial data bit
WATCHDOG TIMER T3
The watchdog timer consists of an 11-bit prescaler and an 8-bit timer formed by special function register T3. The prescaler is incremented by an on-chip oscillator with a fixed frequency of 1MHz. The maximum tolerance on this frequency is -50% and +100%. The 8-bit timer increments every 2048 cycles of the on-chip oscillator. When a timer overflow occurs, the microcontroller is reset and a reset output pulse of 16 x 2048 cycles of the on-chip oscillator is generated at pin RST. The internal RESET signal is not inhibited when the external RST pin is kept low by, for example, an external reset circuit. The RESET signal drives port 1, 2, 3 into the high state and port 0 into the high impedance state. The watchdog timer is controlled by one special function register WDCON with the direct address location A5H. WDCON can be read and written by software. A value of A5H in WDCON halts the on-chip oscillator and clears both the prescaler and timer T3. After the RESET signal, WDCON contains A5H. Every value other than A5H in WDCON enables the watchdog timer. When the watchdog timer is enabled, it runs independently of the XTAL-clock. Timer T3 can be read on the fly. Timer T3 can only be written if WDCON contains the value 5AH. A successful write operation to T3 will clear the prescaler and WDCON, leaving the watchdog enabled and preventing inadvertent changes of T3. To prevent an overflow of the watchdog timer, the user
INTERNAL DATA MEMORY
The internal data memory is divided into three physically separated segments: 256 bytes of RAM, 256 bytes of AUX-RAM, and a 128 bytes special function area. These can be addressed each in a different way. - RAM 0 to 127 can be addressed directly and indirectly as in the 80C51. Address pointers are R0 and R1 of the selected register bank. - RAM 128 to 255 can only be addressed indirectly as in the 80C51. Address pointers are R0 and R1 of the selected register bank. - AUX-RAM 0 to 255 is indirectly addressed in the same way as external data memory with the MOVX instructions. Address pointers are R0, R1 of the selected register bank and DPTR. An access to AUX-RAM 0 to 255 will not affect ports P0, P2, P3.6 and P3.7. An access to external data memory locations higher than 255 will be performed with the MOVX DPTR instructions in the same way as in the 8051 structure, so with P0 and P2 as data/address bus and P3.6 and P3.7 as write and read timing signals. Note that these external data memory cannot be accessed with R0 and R1 as address pointer.

- setting Read Bit Finished (RBF) when the SCL clock pulse has finished and Write Bit Finished (WBF) if there is no arbitration loss detected (i.e., SDA = 0 while SDO = 1) - setting a serial clock Low-to-High detected (CLH) flag - setting a Bus Busy (BB) flag on a START condition and clearing this flag on a STOP condition - releasing the SCL line and clearing the CLH, RBF and WBF flags to resume transfer of the next serial data bit - generating an automatic clock if the single bit data register S1BIT is used in master mode. The following functions must be done in software: - handling the I2C START interrupts - converting serial to parallel data when receiving - converting parallel to serial data when transmitting - comparing the received slave address with its own - interpreting the acknowledge information
- guarding the I2C status if RBF or WBF = 0. Additionally, if acting as master: - generating START and STOP conditions - handling bus arbitration - generating serial clock pulses if S1BIT is not used. Three SFRs control the bit-level I2C interface: S1INT, S1BIT and S1SCS.

OSCILLATOR CHARACTERISTICS
XTAL1 and XTAL2 are the input and output, respectively, of an inverting amplifier. The pins can be configured for use as an on-chip oscillator, as shown in the Logic Symbol. To drive the device from an external clock source, XTAL1 should be driven while XTAL2 is left unconnected. There are no requirements on the duty cycle of the external clock signal, because the input to the internal clock circuitry is through a divide-by-two flip-flop. However, minimum and maximum high and low times specified in the data sheet must be observed.
IDLE MODE
In idle mode, the CPU puts itself to sleep while all of the on-chip peripherals stay active. The instruction to invoke the idle mode is the last instruction executed in the normal operating mode before the idle mode is activated. The CPU contents, the on-chip RAM, and all of the special function registers remain intact during this mode. The idle mode can be terminated either by any enabled interrupt (at which time the process is picked up at the interrupt service routine and continued), or by a hardware reset which starts the processor in the same manner as a power-on reset.
signal INT0 and INT1 must be kept low until the oscillator has restarted and stabilized. An instruction following the instruction that puts the device in the power-down mode will be executed. A reset generated by the watchdog timer terminates the power-down mode in the same way as an external RESET, and only the contents of the on-chip RAM are preserved. The control bits for the reduced power modes are in the special function register PCON.
DESIGN CONSIDERATIONS
At power-on, the voltage on VDD and RST must come up at the same time for a proper start-up. When the idle mode is terminated by a hardware reset, the device normally resumes program execution, from where it left off, up to two machine cycles before the internal reset algorithm takes control. On-chip hardware inhibits access to internal RAM in this event, but access to the port pins is not inhibited. To eliminate the possibility of an unexpected write when idle is terminated by reset, the instruction following the one that invokes idle should not be one that writes to a port pin or to external memory. Table 5 shows the state of I/O ports during low current operating modes.
RESET
A reset is accomplished by holding the RST pin high for at least two machine cycles (24 oscillator periods), while the oscillator is running. To insure a good power-up reset, the RST pin must be high long enough to allow the oscillator time to start up (normally a few milliseconds) plus two machine cycles. At power-up, the voltage on VDD and RST must come up at the same time for a proper start-up.
POWER-DOWN MODE
In the power-down mode, the oscillator is stopped and the instruction to invoke power-down is the last instruction executed. The power-down mode can be terminated by a RESET in the same way as in the 80C51 or in addition by one of two external interrupts, INT0 or INT1. A termination with an external interrupt does not affect the internal data memory and does not affect the special function registers. This makes it possible to exit power-down without changing the port output levels. To terminate the power-down mode with an external interrupt INT0 or INT1 must be switched to level-sensitive and must be enabled. The external interrupt input

NOTES: 1. Capacitive loading on Port 0 and Port 2 may cause spurious noise pulses to be superimposed on the LOW level ouput voltage of ALE, Port 1 and Port 3. The noise is due to external bus capacitance discharging into the Port 0 and Port 2 pins when these pins make a 1-to-0 transition during bus operations. In the worst cases (capacitive loading > 100pF), the noise pulse on the ALE line may exceed 0.8V. In such cases it may be desirable to qualify ALE with a Schmitt Trigger, or use an address latch with a Schmitt Trigger STROBE input. 2. Capacitive loading on Port 0 and Port 2 may cause the HIGH level output voltage on ALE and PSEN to momentarily fall below the 0.9VDD specification when the address bits are stabilizing. 3. The input threshold voltage of P1.6 and P1.7 (SIO1) meets the I2C specification, so a voltage below 0.3VDD will be recognized as a logic 0 while an input above 0.7VDD will be recognized as a logic 1. 4. Under steady state (non-transient) conditions, IOL must be externally limited as follows: 10mA Maximum IOL per port pin: Maximum IOL per 8-bit port: - Port 0: 26mA Ports 1, 2, & 3: 15mA Maximum total IOL for all output pins: 71mA If IOL exceeds the test condition, VOL may exceed the related specification. Pins are not guaranteed to sink current greater than the listed test conditions. 5. Pins of ports 1, 2, and 3 source a transition current when they are being externally driven from 1 to 0. The transition current reaches its maximum value when VIN is approximately 2V. 6. See Figures 9 through 12 for IDD test conditions. 7. IDDMAX at other frequencies can be derived from the figure below, where FREQ is the external oscillator frequency in MHz. IDDMAX is given in mA.
