MLC0xx series
MLC081B

General Description

MLC081B series integrates an 8-bit CPU core, SRAM, timer, D/A and system control circuits by a CMOS silicon gate technology. The ROM can store voice, melody, data table and program.

Twenty-four I/O pins can be used for keypad control, motor control, IR application, LED indicators or communication with other systems. This chip can implement a dual tone melody function with programmable envelope, which can perform harmonic music with different timbres.

This chip is very suitable for instruments, speech products, and intelligent educational toys, etc.

  • * Single chip 8-bit CPU
  • * Operation voltage: 2.4V to 5.5V
  • *Memory
    • *ROM (shared by program and data): 256K ~ 48KBytes
    • *Data RAM: 256 Bytes
  • * 24 input/output pins with wake-up function
  • *Two power-down modes for saving power consumption:
    • *Sleep mode: micro-controller no operation (main- and sub-oscillator still oscillating)
    • *Stop mode: micro-controller no operation(all oscillators stop oscillating)
  • * Two current DAC output for voice synthesizer
  • * Dual-channel melody with programmable envelope
  • * One serial input port and voltage comparator built-in
  • * Three re-loadable 16-bit timers
  • * One watchdog timer built-in
  • *Oscillator
    • *Single or dual clock operation is selected by code option
    • *Main oscillator operation at crystal or RC mode is selected by code option
    • *Crystal/Ceramic oscillator up to 4MHz @ 2.4V and 8MHz @ 3.6Voption
    • *RC oscillator up to 4MHz @ 2.4V
