SH6614 - 4K 4-Bit Microcontroller

General Description

SH6614 (SH6614B, SH6614C) 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 d.
