SH66P51A - OTP 2K 4-bit Microcontroller

Description

SH66P51A is dedicated to infrared remote control transmitter with LCD applications.

This chip integrates the SH6610C 4-bit CPU core with SRAM, OTP ROM, one 8-bit timer, one base timer, LCD driver, programmable input/output driving buffers, carrier synthesizer, and voltage regulator.

Features

  • SH6610C-based single-chip 4-bit micro-controller.
  • OTP ROM: 2K X 16 bits.
  • RAM: 128 X 4 bits (Data RAM).
  • Operation voltage: 1.8V - 3.6V (Typically 3.0V).
  • 18 CMOS bi-directional I/O pins PORTA - PORTE; PORTC shared with LCD SEG1 - 4 PORTD shared with LCD SEG5 - 8 PORTE shared with OSCXI, OSCXO.
  • 4-level subroutine nesting (including interrupts).
  • One 8-bit auto re-load timer/counter.
  • One 8-bit base timer.
  • Warm-up timer.
