The AT89C2051-24SI is a low-voltage, high-performance CMOS 8-bit microcontroller based on the industry-standard 8051 architecture. Manufactured by Microchip Technology, it integrates 2KB of reprogrammable Flash memory with 10,000 write/erase cycles endurance and 128 bytes of internal RAM. The device operates over a supply voltage range of 2.7V to 6V and supports fully static operation from 0 Hz to 24 MHz.
Key peripherals include 15 programmable I/O lines, two 16-bit timer/counters, a full-duplex UART serial port, six interrupt sources, and an on-chip precision analog comparator. The microcontroller also features direct LED drive outputs and low-power idle and power-down modes for energy-sensitive applications.
The AT89C2051-24SI is housed in a 20-lead SOIC package (0.295" width, 7.50mm) with surface mount mounting. It is designed for embedded control applications requiring a compact, cost-effective solution with a rich set of integrated peripherals. The device is compatible with the MCS-51 instruction set, enabling easy migration from existing 8051-based designs.
