ADUC812BSZ

ADuC812 is a fully integrated 12bit data acquisition system incorporating a high performance self-calibrating multichannel ADC, dual DAC and programmable 8bit MCU (8051 instruction set compatible) on a single chip. The programmable 8051 compatible core is supported by 8K bytes flash/EE program memory, 640bytes flash/EE data memory and 256bytes data SRAM on-chip. Additional MCU support functions include Watchdog Timer, Power Supply Monitor and ADC DMA functions. Thirty-two programmable I/O lines, I2C compatible SPI and Standard UART Serial Port I/O are provided for multiprocessor interfaces and I/O expansion. Typical application includes intelligent sensors calibration and conditioning, battery-powered systems (Portable pcs, instruments, monitors), transient capture systems, DAS and communications systems and control loop monitors (optical networks/base stations).
