Atmel AT83C51SND1C / AT89C51SND1C Handbook
The AT8xC51SND1C family combines a C51‑core microcontroller with a hard‑wired MPEG‑I/II‑Layer 3 (MP3) decoder, providing audio playback, volume and tone control, and a rich set of peripheral interfaces. It includes 64 KB of Flash, 2 KB of RAM, and a 4 KB boot flash for in‑system programming via USB or UART.
The document details pin assignments, signal descriptions for ports, timers, audio, USB, MMC, UART, SPI, TWI, ADC, keypad, external memory and system control, as well as electrical characteristics, package options (TQFP80, PLCC84) and typical applications such as MP3 players, car audio, and home multimedia.
