Product Summary
The ADUC812BS is a fully integrated 12-bit data acquisition system incorporating a high performance self-calibrating multichannel ADC, two 12-bit DACs and programmable 8-bit(8051-compatible) MCU on a single chip. The programmable 8051-compatible core of ADUC812BS is supported by 8K bytes Flash/EE program memory, 640 bytes Flash/EE data memory and 256 bytes data SRAM on-chip. Normal, idle and power-down operating modes for both the MCU core and analog converters allow for flexible power management schemes suited to low power applications. The part is specified for 3 V and 5 V operation over the industrial temperature range and is available in a 52-lead, plastic quad flatpack package.
