Microchip (AT80C51RD2-3CSUM) 8 Bit MCU, 40 MHz, 40 Pins, DIP

8 Bit MCU, 8051 Family AT80C51 Series Microcontrollers, 40 MHz, 40 Pins, DIPProduct OverviewThe AT80C51RD2-3CSUM is a 8-bit High-performance Microcontroller retains allfeatures of the 80C52 and adds programmable counter array, 1024 bytes of XRAM,hardware watchdog timer, keyboard interface, versatile serial channel thatfacilitates multiprocessor communication (EUART) and a speed improvementmechanism (X2 mode). The device has two software-selectable modes of reducedactivity and a 8-bit clock prescaler to further reduce power consumption. Inidle mode, the CPU is frozen while the peripherals and the interrupt systemoperate. In the power-down mode, the RAM is saved and all other functions areinoperative.60MHz Maximum operating frequency2.7 to 5.5V Operating voltageApplicationsIndustrialProduct InformationProduct Range: 8051 Family AT80C51 Series MicrocontrollersCPU Speed: 40MHzOperating Frequency Max: 40MHzRAM Memory Size: 1.25KBNo. of Pins: 40PinsMCU Case Style: DIPIC Case / Package: DIPNo. of I/O's: 32I/O'sEmbedded Interface Type: UARTInterfaces: UARTSupply Voltage Min: 2.7VSupply Voltage Max: 5.5VMCU Family: 8051MCU Series: AT80C51Operating Temperature Min: -40°COperating Temperature Max: 85°CIC Mounting: Through Hole
