Single-Chip Flash Microcontroller with MP3 Decoder and Human Interface
Description

The AT8xC51SND1C are fully integrated stand-alone hardwired MPEG I/II-Layer 3 decoder with a C51 microcontroller core handling data flow and MP3-player control. The AT89C51SND1C includes 64K Bytes of Flash memory and allows In-System Programming through an embedded 4K Bytes of Boot Flash memory. The AT83SND1C includes 64K Bytes of ROM memory. The AT80C51SND1C does not include any code memory. The AT8xC51SND1C include 2304 Bytes of RAM memory. The AT8xC51SND1C provides the necessary features for human interface like timers, keyboard port, serial or parallel interface (USB, TWI, SPI, IDE), ADC input, I2S output, and all external memory interface (NAND or NOR Flash, SmartMedia, MultiMedia, DataFlash cards).
