Product Description

The ADuC812 is a fully integrated 12-bit data acquisition system incorporating a high-performance self-calibrating multichannel ADC, dual DAC, and programmable 8-bit MCU (8051 instruction set compatible) on a single chip. The programmable 8051 compatible core is supported by 8K bytes Flash/EE program memory, 640 bytes Flash/EE data memory, and 256 bytes data SRAM on-chip. Additional MCU support functions include Watchdog Timer,

Power Supply Monitor, and ADC DMA functions. Thirty-two programmable I/O lines, I2 C compatible SPI, and Standard UART Serial Port I/O are provided for multiprocessor interfaces and I/O expansion.
