GENERAL DESCRIPTION  
Specified for 3 V and 5 V Operation  
Normal, Idle, and Power-Down Modes  
Power-Down: 20 A @ 3 V  
The ADuC831 is a fully integrated 247 kSPS data acquisition  
system incorporating a high performance self-calibrating multi-  
channel 12-bit ADC, dual 12-bit DACs, and programmable  
8-bit MCU on a single chip.  
APPLICATIONS  
Optical Networking—Laser Power Control  
Base Station Systems  
Precision Instrumentation, Smart Sensors  
Transient Capture Systems  
DAS and Communications Systems  
The microcontroller core is an 8052, and therefore 8051-  
instruction-set compatible with 12 core clock periods per machine  
cycle. 62 kBytes of nonvolatile Flash/EE program memory are  
provided on-chip. Four kBytes of nonvolatile Flash/EE data  
memory, 256 bytes RAM and 2 kBytes of extended RAM are  
also integrated on-chip.  
Pin compatible upgrade to existing ADuC812 systems  
that require additional code or data memory. Runs  
from 1 MHz–16 MHz to external crystal.  
The ADuC831 also incorporates additional analog functionality  
with two 12-bit DACs, power supply monitor, and a band gap  
reference. On-chip digital peripherals include two 16-bit Σ-∆  
DACs, dual output 16-bit PWM, watchdog timer, time interval  
counter, three timers/counters, Timer 3 for baud rate generation  
and serial I/O ports (I2C, SPI and UART).  
The ADuC832 is also available. Functionally is the same  
as the ADuC831, except the ADuC832 runs from a 32 kHz  
external crystal with on-chip PLL.  
On-chip factory firmware supports in-circuit serial download and  
debug modes (via UART), as well as single-pin emulation mode  
via the EA pin. The ADuC831 is supported by QuickStart™ and  
QuickStart Plus development systems featuring low cost software  
and hardware development tools. A functional block diagram of  
the ADuC831 is shown above with a more detailed block diagram  
shown in Figure 1.

The part is specified for 3 V and 5 V operation over the extended  
industrial temperature range, and is available in a 52-lead plastic  
quad flatpack package and in a 56-lead chip scale package.
