4-Bit Microcontroller with Built-in LCD Driver and Melody Circuit
GENERAL DESCRIPTION
The MSM64155A (1.5 V)/64155AL (3.0 V) is a high-performance 4-bit microcontroller that
incorporates Oki-original CPU core nX-4/20.
The MSM64155A/64155AL has an LCD driver for up to 240 segments, an event counter, and
melody circuits. It is best suited for applications such as clocks and LCD games.
• OTP version (for program evaluation) : MSM64P155/64P155L
(The power polarity and operating voltage of the MSM64P155/64P155L are different from the
MSM64155A/64155AL. For details, refer to the "MSM64P155 User's Manual".)
1 port ¥ 2 bits (pull-down resistor input/high-impedance
input selectable
1 port ¥ 4 bits (pull-down resistor input/high-impedance
input selectable)
Note:Pins marked as (NC) are no-connection pins which are left open.

Bias output for LCD driver (–4.5 V)
For connection to capacitors that generate bias for the

Negative power supply voltage pin for internal logic
(An internally generated constant voltage is present at this pin.)
Clock oscillation pins:
Either a crystal (32.768 kHz) and a capacitor (10 to 30 pF)
are connected to these pins or a resistor (1 MW) is.
Input pins for test
System reset input pin :
Setting this pin to "H" level puts this device into a reset state.
Then, setting this pin to "L" level starts executing an instruction
from address 000H.
This pin is internally connected to V
SS1
or V
through a
SS2
pull-down resistor.

When configured for secondary functions, an external
interrupt and capture circuit trigger input are allocated.
If P2.0 to P2.3 are set to "H" level, the device enters system
reset mode.
I2-bit input port (port 3) :
Select between pull-down resistor input and high impedance
input with the port 3 control register (P3CON).
When configured for a secondary function, an external
interrupt is allocated to P3.0 and an event counter is
allocated to P3.1.

output and CMOS output with the port 6 control register
(P6CON). When configured for a secondary function, an
external interrupt is allocated.
