DESCRIPTION
Aplus’ aMTP777 is a 4K-byte 8-bit MCU based Voice controller IC. It is fabricated with Standard
CMOS process with embedded voice storage memory. Voice data is stored in an external multi-
programmable SPI flash with 4-bit ADPCM compression at different sampling rate. 10-bit/8-bit PCM
is also available as user selectable option 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. User selectable triggering and output signal options provide
maximum flexibility to various applications. Built-in resistor controlled oscillator, 10-bit resolution
current mode D/A output and PWM direct speaker driving minimize the number of external
components. Volume control for both DAC and VOUT output is available.
