The AT89C55WD-24JU is a low-power, high-performance CMOS 8-bit microcontroller with 20K bytes of Flash programmable memory and 256 bytes of RAM. It is based on the industry-standard 8051 core and is compatible with MCS-51 products. The device operates at a maximum frequency of 24MHz over a supply voltage range of 4V to 5.5V. It includes 32 programmable I/O lines, three 16-bit timer/counters, a full-duplex serial port (UART/USART), eight interrupt sources, and a hardware watchdog timer. The microcontroller supports low-power idle and power-down modes, with interrupt recovery from power-down. The Flash memory has an endurance of 10,000 write/erase cycles. The AT89C55WD-24JU is packaged in a 44-lead PLCC (J-Lead) surface-mount package measuring 16.66mm x 16.662mm x 4.064mm. It is rated for operation from -40°C to 85°C. This device is suitable for a wide range of embedded control applications requiring a reliable 8-bit MCU with reprogrammable memory.
