GENERAL DESCRIPTION

The MSM6641, powered by a single battery, is a 4-bit microcontroller fabricated in OKI’s low voltage CMOS technology. A remote-control output generator built into this device provides remote-control output.

The MSM6641 is best suited to remote-control applications.

FEATURES

? Operating range

Operating voltage : 1.5 V (MSM6641)

3.0 V (MSM6641E)

Operating frequency : 1 MHz

Operating temperature : –20 to +70°C

? Memory space

ROM : 4096 words × 17 bits

RAM : 64 words × 4 bits

? Minimum instruction execution time : 16 μs

? I/O port

Input port : 2 ports x 4 bits

1 port x 1 bit

Output port : 2 ports x 4 bits

1 port x 1 bit

? Remote-control output port : 1

The remote-control output circuit consists of a carrier generator, a guide pulse and data pulse generator, and an output waveform controller. The remote control output can be provided by setting the control registers.

? Key-On Wake-Up function

Oscillation can be stopped to turn off microcontroller operation. Application of predetermined input levels to the input ports turns on oscillation and microcontroller operation.

? Halt release timers : 4

Timer frequencies are selectable.

? Watchdog timers : 2

? Clock : 1 MHz ceralock resonator

? Power supply voltage : 1.5 V/3.0 V (mask option)

? Package:

24-pin plastic SOP (SOP24-P-430-K) (Product name : MSM6641-￥￥GS-K, MSM6641E-xxGS-K) Chip
