SH6631A - Mask 4-bit Microcontroller

Description

SH6631A is dedicated to infrared remote control transmitter applications.

This chip integrates the SH6610C 4-bit CPU core with SRAM, program ROM, an 8-bit timer, and programmable input/output driving buffers and carrier synthesizer.

Features

  • SH6610C-based single-chip 4-bit micro-controller ROM: 1024 X 16 bits ROM RAM: 48 X 4 bits RAM (Data Memory) Operation voltage: 1.8V.
  • 3.6V (Typically 3.0V) 14 CMOS bi-directional I/O pins 4-level subroutine nesting (including interrupts) One 8-bit auto re-loadable timer/counter Warm-up timer for power-on reset Powerful interrupt sources: - Internal interrupt (Timer0). - External interrupts: PortB & PortC (Falling edge). Built-in remote control carrier synthesizer FOSC/8 or FOSC/12 by so.
