4-Bit Microcontroller with Built-in Dual-Slope Type A/D Converter and LCD Driver
GENERAL DESCRIPTION
The MSM64167 is a low power 4-bit microcontroller that employs Oki's original CPU core nX4/20. The MSM64167 contains a dual-slope type A/D converter with a 4-channel input, LCD driver for up to 108 segments, and buzzer output port. The MSM64167 is best suited for applications such as low power, high precision thermometers, barometers, 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 4064 bytes of address 000H to address 0FDFH. No program can be stored in the test program area.

Data Memory The data memory area consists of 8 banks and each bank has 256 nibbles (256 4 bits). The data RAM is assigned to BANK 7 and peripheral ports are assigned to BANK 0.

Data Memory Map Half 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 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.

FUNCTIONAL DESCRIPTION
CPU Peripheral Functions * A/D converter (ADC) The MSM64167 has a 4-channel input dual-slope type A/D converter. In dual-slope A/D conversion, the relationship between integral voltage and time is given by: Vin/Vr = t1/t2 where, t1 = given time for which an analog input voltage is integrated Vr = reference voltage Vin = voltage resulted from charging for t1 t2 = time required to discharge the voltage, from Vr to Vin From the above equation, Vin is found. The range of Vin is -0.8 0.4 V. The A/D converter resolution time is programmable. The A/ D converter has a preamplifier for amplifying a microvoltage. It is suited to applications such as thermometers, pressure gauges, and hygrometers. * LCD driver (LCD) The MSM64167 has a built-in LCD driver for 31 outputs. The LCD driver consists of 31 4-bit display registers (DSPR0-30), the Display Control Register (DSPCON), a 31-output LCD driver circuit, and a bias generation circuit (BIAS). 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. L0 to L7 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 ------- 108 segments 1/3 duty 1/3 bias method ------- 84 segments 1/2 duty 1/2 bias method ------- 58 segments * Port (P0, P1, P2) The MSM64167 has three input-output ports (P0, P1, P2) with 4 bits each. Each bit of the ports can be configured to be (1) an input or output, (2) pull-up/pull-down resistor input or high impedance input, and (3) NMOS open drain output or CMOS output. A change in the input level of each pin of P0 and P1 generates an external interrupt 0 request, and a change in the input level of each pin of P2 generates an external interrupt 1 request. The serial port function and the timer function are assigned as the secondary functions. * Buzzer driver (BD) The MSM64167 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). * Serial port (SIOP) The MSM64167 has a serial port (SIOP). The serial port is a synchronous/asynchronous selectable serial communication port. The transmit section and the receive section are independent of each other, which allows simultaneous operation of transmission and receiving.

MSM64167
* Watchdog timer (WDT) The MSM64167 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. * Timer (TM) The MSM64167 contains a 16-bit timer (TM). The timer has three operation modes: auto-reload mode, capture mode, and clock frequency measuring mode. It counts at 32.768 kHz or 700 kHz or by an external clock. The timer is used for pulse generation, time measurement, etc., and is also used as an A/D conversion counter at A/D conversion and as a baud rate generator at serial communication. * Clock generation circuit (2CLK) The MSM64167 has a clock generation circuit (2CLK) that generates clocks of two types: lowspeed and high-speed. The circuit consists of a 32.768 kHz crystal oscillation circuit, a 700 kHz RC oscillation circuit, and a clock control section. This circuit generates the system clock (CLK), crystal oscillation clock (32.768 kHz), and RC oscillation clock (700 kHz). The system clock is the basic operation clock of the CPU, and the crystal oscillation clock is the basic operation clock of the time-base counter and the buzzer driver. The crystal oscillation clock and RC oscillation clock are supplied to the timer to become a timer clock. The system clock frequency is switched between 32.768 kHz (output of the crystal oscillation circuit) and 700 kHz (output of the RC oscillation circuit) based on the contents of the frequency control register (FCON). Note: The oscillation frequency of the RC oscillation circuit varies depending on the value of external resistor (ROS), operating voltage (VSS2), and ambient temperature (Ta). * Time base counter (TBC) The MSM64167 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 timer, the watchdog timer, the time base interrupt, the sampling clocks of each port, and the LCD driver. * Interrupt (INTC) The MSM64167 has ten interrupt sources (10 vector addresses), of which two are external interrupts from ports and eight are internal interrupts. Of the ten interrupt sources, only the watchdog interrupt cannot be disabled (non-maskable interrupt). The other nine 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.

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).
