Microchip Technology's AT80C51RD2-3CSUM is an 8-bit microcontroller built around the robust 80C51 CPU core, operating at a maximum clock frequency of 40MHz. This CMOS device features 1280 bytes of on-chip data RAM and a ROM-less architecture, requiring external program memory. It offers 32 general-purpose I/O lines, three timers, and a watchdog timer. Peripheral support includes POR (Power-On Reset), PWM, and an EUART for serial communication. The microcontroller operates within a supply voltage range of 5.0V to 5.5V and has an operating temperature range of -40°C to +85°C. The AT80C51RD2-3CSUM is housed in a 40-pin PDIP package, suitable for through-hole mounting. This component finds application in industrial automation, consumer electronics, and automotive systems.
