SH6614D - 4K 4-Bit Microcontroller

General Description

SH6614D is a single chip microcontroller integrated with SRAM, timer and dual-tone PSG, LCD driver, and I/O port.

This chip builds in a dual-oscillator to enhance the total chip performance.

Key Features

  • SH6610C-based single-chip 4-bit microcontroller ROM: 4096 X 16 bits RAM: 512 X 4 bits Operation voltage: 2.4V.
  • 6.0V 8 CMOS bi-directional I/O pins 4-Level subroutine nesting (include interrupts) One 8-bit auto re-load timer/counter Wem-up timer for power-on reset Powerful interrupt sources: - External interrupts ( INT0 ) - Internal interrupt (Timer0) - Internal interrupt (Base Timer) - Port's falling edge interrupt: PORTB ( INT1 ) 8-bit Base timer LCD driver: 240 dots (1/8 duty 1/4 bias.
