CMOS 8-Bit Microcontroller
GENERAL DESCRIPTION
The OKI MSM80C48/MSM80C49/MSM80C50 are 8-bit, low-power, high-performance micro-
controllers implemented in silicon-gate complementary metal-oxide semiconductor technology.
Integrated within these chips are 8K/16K/32K bits of mask program ROM, 512/1024/2048 bits
of data RAM, 27 I/O lines, built-in 8 bit timer/counter, and oscillator. Program memory and data
paths are byte wide. Eleven new instructions have been added to the NMOS version's instruction
set, thereby optimizing power down, port data transfer, decrement and port float functions.
Available in 40-pin plastic DIP (RS) or 44-pin plastic flat packages QFP (GSK).

PIN DESCRIPTIONS (Continued)
Symbol
XTAL1
(Crystal 1)
Type
I
Description
One side of the internal crystal oscillator. An external clock can also be input.
XTAL2
(Crystal 2)
O Other side of the internal crystal oscillator.
VCC — Power supply pin
VDD — Standby control input. Normally, "1" level. When set to "0" level, oscillation is
stopped and prosessor goes into standby mode.
VSS — GND
Note: A minimum of two machine cycles are required in RESET pulse duration under the
specified power supply and stable oscillator frequency.
