The ADuC831 is a fully integrated 247 kSPS data acquisitionsystem incorporating a high performance self-calibrating multi-channel12-bit ADC, dual 12-bit DACs, and programmable8-bit MCU on a single chip.The microcontroller core is an 8052, and therefore 8051-instruction-set compatible with 12 core clock periods per machinecycle. 62 kBytes of nonvolatile Flash/EE program memory areprovided on-chip. Four kBytes of nonvolatile Flash/EE datamemory, 256 bytes RAM and 2 kBytes of extended RAM arealso integrated on-chip.The ADuC831 also incorporates additional analog functionalitywith two 12-bit DACs, power supply monitor, and a band gapreference. On-chip digital peripherals include two 16-bit Σ-∆DACs, dual output 16-bit PWM, watchdog timer, time intervalcounter, three timers/counters, Timer 3 for baud rate generationand serial I/O ports (I2C, SPI and UART).On-chip factory firmware supports in-circuit serial download anddebug modes (via UART), as well as single-pin emulation modevia the EA pin. The ADuC831 is supported by QuickStart™ andQuickStart Plus development systems featuring low cost softwareand hardware development tools. The part is specified for 3 V and 5 V operation over the extendedindustrial temperature range, and is available in a 52-lead plasticquad flatpack package and in a 56-lead chip scale package.
