The AT89C55WD-24PU is an 8-bit microcontroller based on the 8051 core architecture, manufactured by Microchip Technology. It features 20KB of reprogrammable Flash memory with 10,000 write/erase cycles and 256 bytes of internal RAM. The device operates at a clock frequency of up to 24MHz and supports a supply voltage range of 4V to 5.5V. It includes 32 programmable I/O lines, three 16-bit timer/counters, eight interrupt sources, and a full-duplex UART/USART serial channel. An internal oscillator and hardware watchdog timer are integrated. The microcontroller is packaged in a 40-pin PDIP (0.600", 15.24mm) for through-hole mounting, with dimensions 52.58mm x 13.97mm x 4.826mm. It is designed for embedded control applications requiring moderate memory and I/O, and supports low-power idle and power-down modes. The device is RoHS3 compliant and lead-free.
