aMTP777 is a 4K-byte 8-bit MCU based Voice controller IC with embedded voice storage memory. Voice data is stored in an external multiprogrammable SPI flash with 4-bit ADPCM compression at different sampling rate. 10-bit/8-bit PCM is also available to improve sound quality. There are upto nineteen programmable I/O pins. Key trigger and Parallel CPU trigger mode can be configured according to different application requirement.
This IC can also be used as a LED driver to control LED flashing and dimming.
