MSM65344A
8-Bit Microcontroller with A/D Converter (with LCD Driver)
GENERAL DESCRIPTION
The MSM65344A is a high performance 8-bit microcontroller that employs OKI original CPU
core nX-8/50. The MSM65344A includes 12K-byte program memory, 384-byte data memory,
LCD driver, timer, PWM, serial I/O, and 8-bit A/D converter. Also available is the MSM65P344,
which replace the on-chip program memory with one-time PROM.

Description
8-bit input-output port (port 0):
Each of bits 0 to 7 can be configured to be an input
or an output by the direction register of port 0
(P0DIR).
In addition to the basic function as an input-output
port, a secondary function is allocated to each of
P0.0 through P0.7. Refer to the next table.
3-bit input-output port (port 1):
Each of bits 1.2 to 1.4 is configured to be input or
output by the direction register of port 1 (P1DIR).
In addition to the basic function as an input-output
port, a secondary function is allocated to each of
P1.2 through P1.4. Refer to "PIN DESCRIPTION
(Secondary Function)".
6-bit input port (port 3):
Each of P3.0 to P3.5 functions as analog input
channel of A/D converter.
8-bit input-output port (port 4):
8-bit input-output port.
7-bit input-output port (port 5):
Each of bits 5.0 to 5.6 can be configured to be an
input or an output by the direction register of
port 5 (P5DI).
1-bit input port (port 6.0):
1-bit input port.
1-bit output port (port 6.1):
Pulled high when reset is done. If this pin is set to
the "0" level during reset, this IC goes into a test
mode, disabling execution of the user program.
6-bit input-output port (port 6):
6-bit input-output port.
8-bit input-output port (port 7):
Each of bits 7.0 to 7.7 can be configured to be an
input or an output by the direction register of
port 7 (P7DIR).
In addition to the basic function as the input-output
port, a secondary function is allocated to each of
P7.4 through P7.7. Refer to the next table.
