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, I
2
C-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 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.
