Microchip Technology, Inc. Microcontrollers AT80C51SND1C-ROTIL

The AT80C51SND1C-ROTIL is a ROMless microcontroller based on the 8-bit C51 core, operating at a maximum frequency of 40 MHz. It features 2304 bytes of internal RAM and is designed for applications requiring audio processing, particularly as a stand-alone MP3 decoder. The device supports various audio output formats, including PCM and I¬=S, and includes a USB 1.1 controller for full-speed data transmission. The microcontroller is equipped with multiple interfaces, including SPI, TWI, and IDE, and offers two 10-bit ADC channels for analog input. It also provides general-purpose I/O capabilities, timers, and a hardware watchdog timer. The operating voltage is 3V with a typical current consumption of 25 mA at 25¬8C, and it operates within a temperature range of -40¬8C to +85¬8C. The AT80C51SND1C-ROTIL is available in a TQFP package, making it suitable for compact designs in audio applications such as PDAs, cameras, and car audio systems.
