This version: Sep. 27,1999
Previous version: Jun. 22,1999
4-Bit Microcontroller with Built-in RC Oscillation Type A/D Converter and LCD Driver
GENERAL DESCRIPTION
The ML64P168 is a one-time-programmable ROM-version product, which has one-time PROM (OTP)
as internal program memory. On the other hand, the ML64168 is a mask ROM-version product, which
has mask ROM as internal program memory.
Unlike the mask ROM-version product (ML64168), the ML64P168 cannot be supplied in the form of a
chip.
The ML64P168 has two operation modes, microcontroller operation mode and PROM mode. The
microcontroller operation mode is used to operate the ML64P168 like a ML64168 and the PROM
mode is used to program or read the PROM.
The ML64P168 is a low power 4-bit microcontroller incorporating the Oki’s original CPU core nX4/30.
The ML64P168 provides a minimum instruction execution time of 4.3µs (@700kHz).
The ML64P168 contains 8160-byte program memory, 512-nibble data memory, three 4-bit input-output
ports, 4-bit input port, 4-bit output port, 2-channel RC oscillation type A/D converter, LCD driver for
up to 120 segments, and buzzer output port.
APPLICATION
The ML64P168 is best suited for low power, high precision thermometers and hygrometers.

Voltage Regulator for LCD Driver (selectable by mask option)
The LCD panel display is stable regardless of temporary supply voltage drop, because the
voltage generated by the voltage regulator for LCD driver is supplied to the bias voltage
generator as a reference voltage.
LCD Operating Voltage

Data Memory Map
Half the BANK 7 of 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 5.

ML64P168
FUNCTIONAL DESCRIPTION
CPU Peripheral Function
∙ A/D converter ( ADC )
The ML64P168 has a built-in two-channel RC oscillation A/D converter. The A/D converter is
composed of a two-cannel 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 cannel of
the 2-channel RC oscillation circuit, it is also possible to extend measure ranges or measure at two
places.
∙ Serial port ( SIOP )
The ML64P168 has an 8-bit synchronous serial port. Receive/transmit operation of the serial port is
performed simultaneously and the serial transfer clock can select either internal or external mode.
Direction of transfer data can be big endian or little endian. Each pin of the serial port is assigned as
secondary functions of P3.3 and P4.0 to P4.2. Setting each bit of SIN,SOUT, SPR and SCLK of
P33CON and P40CON to P42CON to “1” makes each pin valid.
∙ LCD driver ( LCD )
The ML64P168 has a built-in LCD driver for 34 outputs.
The LCD driver consists of 31× 4-bit display registers ( DSPR0-30 ), the Display Control Register
( DSPCON ), a 34-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 ( VDD1 = 1.2V ) 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: 1/4duty, 1/3duty and 1/2duty. 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.
L26 to L33 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:
1/4duty, 1/3 bias method ----------- 120 segments
1/3duty, 1/3 bias method ----------- 93 segments
1/2duty, 1/2 bias method ----------- 64 segments
∙ Buzzer driver ( BD )
The ML64P168 has a built-in buzzer driver with 15 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 ML64P168 captures 32Hz to 256Hz output of the time base counter at the falling of Port 0.0 or
Port 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 ML64P168 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 16Hz output and a watchdog
timer control register ( WDTCON ) to reset WDTC.
∙ Clock generation circuit ( 2CLK )
The clock generation circuit ( 2CLK ) in the ML64P168 contains a 32.768kHz crystal oscillation
circuit, a 700kHz RC oscillation circuit, and a clock control port. This circuit generates the system
clock ( CLK ) and the time base clock ( 32.768kHz ).
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 32.768kHz ( the output of the crystal oscillation circuit ) and 700kHz ( 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 ML64P168 has a built-in time base counter ( TBC ) that generates clocks to be supplied to
internal peripheral circuit. The time base counter is composed of 15 binary counters, and a 1/10
frequency dividing circuit. The count clock of the time base is driven by the oscillation clock
( 32.768kHz ) 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, P4 )
: 3 ports × 4bits
Pull-up ( pull-down ) resistor input or high-impedance input, CMOS output or NMOS open
drain output: these can be specified for each bit; external 0 interrupt
Input port ( P0 )
: 1 port × 4bits
Pull-up ( pull-down ) resistor input or high-impedance input; external 1 interrupt
Output port ( P1 )
: 1 port × 4bits
CMOS output or NMOS open drain output

∙ Interrupt ( INTC )
The ML64P168 has 10 interrupt sources ( 10 vector address ), of which two are external interrupts
from ports and eight are internal interrupts.
Of the ten interrupt sources, only the watchdog timer 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.
∙ 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).
