AT89C51ED2-SLSUM Description

Short technical summary and product information.

The Microchip AT89C51ED2-SLSUM is an 8-bit microcontroller built on the high-performance 80C51 core architecture. It features 64KB of on-chip Flash program memory, 2KB of RAM, and an additional 2KB EEPROM block for data storage. The device supports a maximum internal code execution frequency of 60MHz and external code execution up to 40MHz, with a supply voltage range of 2.7V to 5.5V.

 

This microcontroller includes a rich set of peripherals including three 16-bit timer/counters, five PWM channels, a watchdog timer, and a full-duplex enhanced UART with dedicated baud rate generator. It also provides an SPI interface for serial communication and a programmable counter array for high-speed output, compare/capture, and PWM generation. The device integrates a power-on reset and power-fail detection circuit.

 

The AT89C51ED2-SLSUM is housed in a 44-pin PLCC (J-Lead) package measuring 16.6mm x 16.6mm, designed for surface mount assembly. It operates over the industrial temperature range of -40°C to 85°C, making it suitable for demanding environments. The device is RoHS3 compliant and lead-free.
