GENERAL 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 instruc-

tion set compatible) on a single chip.

8K Bytes On-Chip Flash/EE Program Memory

640 Bytes On-Chip Flash/EE Data Memory

256 Bytes On-Chip Data RAM

16M Bytes External Data Address Space

64K Bytes External Program Address Space

8051 Compatible Core

12 MHz Nominal Operation (16 MHz Max)

3 16-Bit Timer/Counters

High Current Drive Capability—Port 3

9 Interrupt Sources, 2 Priority Levels

Power

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.

Specified for 3 V and 5 V Operation

Normal, Idle, and Power-Down Modes

On-Chip Peripherals

Normal, idle, and power-down operating modes for both the

MCU core and analog converters allow flexible power manage-

ment schemes suited to low power applications. The part is

specified for 3 V and 5 V operation over the industrial tem-

perature range and is available in a 52-lead, plastic quad

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