Specification

Overview

  • General Description

    This is an 8-bit RISC type microprocessor with low power, high speed CMOS technology. Integrated onto a single chip are on-chip Watchdog Timer (WDT), RAM, ROM, programmable real time clock/counter, internal interrupt, power down mode, ASPCM voice synthesizer(decoder), voice ROM, Current DAC and tri-state I/O. It provides a single IC solution to design an electric wall mount clock.

  • Features & Benefits

    • Operating Voltage Range

      • 2.5V~3.6V (Normal mode under 14.331MHz~17.913MHz)
      • 2.2V~3.6V (Normal mode under 447.829KHz~14.331MHz)
      • 2.2V~3.6V (Sleep/Idle/Green mode)

    • CPU

      • 8-bit RISC kernel
      • 99.9% single instruction cycle commands

    • Clock

      • 32.768 kHz clock source
      • Built-in PLL to generate main clock 3.5826 MHz x 0.125, 0.25, 0.5, 1, 2, 3, 4 or 5

    • Timer and Counter

      • Watchdog timer: Programmable free running on-chip watchdog Timer
      • TCC: 8-bit real time clock/counter (TCC) with 8-bit prescaler
      • COUNTER1: 8-bit counter with 8-bit prescaler can be an interrupt source
      • COUNTER2: 8-bit counter with 8-bit prescaler can be an interrupt source

    • Memory

      • 16K x 13 on-chip program ROM
      • 40K x 5 on-chip voice ROM (the max. timing from voice ROM enable to its data finish = 1.25μs)
      • 0.25k bytes on-chip Data RAM
      • 144 bytes common registers

    • I/O

      • Up to 26 bi-directional tri-state I/O ports (18 independent I/O)
      • I/O with internal Pull high, wake-up and interrupt functions

    • Operation Mode

      • Sleep mode: CPU, main clock and 32.768KHz clock turn off
      • IDLE mode: CPU and main clock turn off, 32.768KHz clock turn on
      • Green mode: main clock turn off, CPU and 32.768KHz clock turn on
      • Normal mode: CPU, main clock and 32.768KHz clock turn on

    • Interrupt

      • Selective signal sources and overflow interrupt
      • STACK: 8 level stack for subroutine nesting
      • 8 interrupt source: 4 external, 4 internal

    • Reset

      • Power-on reset, /POVD reset (by code option) or external /RESET pin

    • DAC

      • 8-bit current DAC
      • Can be accessed by ASPCM hardware or from DAC input register
