GENERAL DESCRIPTION
The ADuC832 is a complete smart transducer front end, integrat-
ing a high performance self-calibrating multichannel 12-bit ADC,
dual 12-bit DACs, and programmable 8-bit MCU on a single chip.
The device operates from a 32 kHz crystal with an on-chip PLL
generating a high frequency clock of 16.77 MHz. This clock is, in
turn, routed through a programmable clock divider from which
the MCU core clock operating frequency is generated. The micro-
controller 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.
4 kBytes of nonvolatile Flash/EE data memory, 256 bytes RAM,
and 2 kBytes of extended RAM are also integrated on-chip.
The ADuC832 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 -
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 (SPI, I
2
C, 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 ADuC832 is supported by QuickStart
and
QuickStart Plus development systems featuring low cost software
and hardware development tools. A functional block diagram of
the ADuC832 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 a 56-lead chip scale package.
