Pin compatible upgrade to existing ADuC812 systems
that require additional code or data memory. Runs
from 1 MHz–16 MHz to external crystal.
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.

GENERAL DESCRIPTION
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.
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.
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 (I
2
C, SPI and UART).
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.
