Manufacturer: OKI Electric

Overview: E2E1022-27-Y4 ¡ Semiconductor MSM80C48/49/50 MSM80C35/39/40 ¡ Semiconductor CMOS 8-Bit Microcontroller This version: Jan. 1998 MSM80C48/49/50, MSM80C35/39/40 Previous version: Nov.

General Description

The OKI MSM80C48/MSM80C49/MSM80C50 are 8-bit, low-power, high-performance microcontrollers implemented in silicon-gate plementary 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.

Key Features

  • Lower power consumption enabled by CMOS silicon gate process.
  • Completely static operation.
  • Improved power-down feature.
  • Instruction cycle : 1.36 ms (11 MHz) VCC=4.5 to 6.0 V (MSM80C48/49) 2.5 ms (6 MHz) VCC=3.5 to 6.0 V (MSM80C50).
  • 111 instructions.
  • All instructions are usable even during execution of external ROM instructions.
  • Operation facility Addition, logical operations, and decimal adjust.
  • Program memory (ROM) : 1K w.
