MLC0xx series
MLC331B

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.
