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.  
UART and SPI® Serial I/O
