ADUC831BSZ

ADuC831 is a fully integrated 247KSPS data acquisition system incorporating a high performance self-calibrating multichannel 12bit ADC, dual 12bit DACs and programmable 8bit 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. 62Kbytes of non-volatile flash/EE program memory are provided on-chip. 4Kbytes of non-volatile Flash/EE data memory, 256bytes RAM and 2Kbytes of extended RAM are also integrated on-chip. Typical application includes optical networking laser power control, base station systems, precision instrumentation, smart sensors, transient capture systems and DAS and communications systems.

• DC performance of ±1LSB INL and AC performance of 71dB SNR
• DMA controller for high speed ADC-to-RAM capture
• Two 12bit (monotonic) voltage output DACs, dual output PWM/Ʃ-Δ DACs
• On-chip temperature sensor function ±3°C and on-chip voltage reference
• 8051 compatible instruction set (16MHz max), dual data pointer and extended 11bit stack pointer
• On-chip peripherals: TIC, UART, I2C® and SPI® serial I/O, WDT, PSM
• Specified for 3V, 5V operation and normal, Idle, power-down modes
• Power down of 20A at 3V
• 52 lead MQFP package
• Operating temperature range from -40°C to 125°C
