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.
Applications
- Optical networking—laser power control
- Base station systems
