GENERAL DESCRIPTION

The ADuC812 is a fully integrated 12-bit data acquisition

system incorporating a high performance self-calibrating

multichannel ADC, two 12-bit DACs and programmable 8-bit

(8051-compatible) MCU 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. 32 Program-

mable I/O lines, I²C-compatible, SPI and Standard UART

Serial Port I/O are provided for multiprocessor interfaces and

I/O expansion.

32 Programmable I/O lines

High Current Drive Capability—Port 3

Nine Interrupt Sources, Two Priority Levels

POWER

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 for flexible power man-

agement schemes suited to low power applications. The part is

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

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

package.
