Product Details
| 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 instructionset 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 managementschemes suited to low power applications. The part isspecified for 3 V and 5 V operation over the industrial temperaturerange and is available in a 52-lead, plastic quadflatpack package. |
