The AT89C51ED2-SMSUM is an 8-bit microcontroller based on the 80C51 core, manufactured by Microchip Technology. It operates at up to 60 MHz and features 64KB of on-chip Flash program memory, 2KB of RAM, and 2KB of EEPROM for data storage.
The device includes 50 general-purpose I/O lines, three 16-bit timer/counters, a full-duplex UART, an SPI interface, and five PWM channels. It also integrates a power-on reset (POR), programmable watchdog timer (WDT), and in-system programming (ISP) support via standard VCC.
The microcontroller operates over a supply voltage range of 2.7V to 5.5V and an industrial temperature range of -40°C to 85°C. It is RoHS3 compliant and has an MSL rating of 1 (unlimited). The device is housed in a 68-lead PLCC package with J-leads for surface mount assembly.
With its rich peripheral set and high-speed 8051 architecture, the AT89C51ED2-SMSUM is suitable for embedded control applications requiring moderate processing power, multiple I/Os, and serial communication. The on-chip EEPROM and Flash memory enable firmware updates and data logging.
