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, and in a 56-lead, chip scale package.
