Hot-selling and scarce ADUC812BSZ 12-Bit ADC with Embedded Flash MCU MQFP-52 spot stock

Product Descriptions

The ADuC812 is a fully integrated 12-bit data acquisition systemincorporating a high performance self-calibrating multichannelADC, dual DAC, and programmable 8-bit MCU (8051 instruction set compatible) on a single chip .

The programmable 8051 compatible core is supported by 8Kbytes Flash/EE program memory, 640 bytes Flash/EE datamemory, and 256 bytes data SRAM on-chip .

Additional MCU support functions include Watchdog Timer,Power Supply Monitor, and ADC DMA functions. Thirty-twoprogrammable I/O lines, I²C compatible SPI and StandardUART Serial Port I/O are provided for multiprocessor interfacesand I/O expansion .

Normal, idle, and power-down operating modes for both theMCU core and analog converters allow flexible power management schemes suited to low power applications . The part isspecified for 3 V and 5 V operation over the industrial temperature range and is available in a 52-lead, plastic quadflatpack package, and in a 56-lead, chip scale package .
