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 (I²C, 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.

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.

Product Details

Development system for evaluation of the ADuC831, 8-Channel 12-Bit ADC + Dual 12-Bit DAC + 62K-Byte Flash MCU.

The QuickStart Kits for the ADuC8x-series (8052-core) Precision Analog Microcontrollers feature serial-port download/debug capability and an assembly-source debugging environment.

ADI also provides a non-intrusive emulation POD called the USB-EA-CONVZ allowing assembly & C-source debugging.

It can be ordered separately.
