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, I2C compatible SPI and Standard UART Serial Port I/O are provided for multiprocessor interfaces and I/O expansion. Normal, idle, and power-down operating modes for both the MCU core and analog converters allow flexible power management schemes suited to low power applications. The part is specified for 3 V and 5 V operation over the industrial temperature range and is available in a 52-lead, plastic quad flatpack package. Applications

* Intelligent Sensors Calibration and Conditioning

* Battery-Powered Systems (Portable PCs, Instruments,

Monitors)

* Transient Capture Systems

* DAS and Communications Systems

* Control Loop Monitors (Optical Networks/Base Stations)
