The AT89C55WD-24JU is an 8-bit microcontroller built on the industry-standard 8051 core. It integrates 20KB of reprogrammable Flash memory and 256 bytes of RAM, operating over a 4V to 5.5V supply range. Fully static logic allows the clock to be stopped or run down to 0Hz; the specified maximum clock frequency is 24MHz.
The device includes 32 programmable I/O lines, three 16-bit timer/counters, a programmable serial channel, and a hardware watchdog timer. It supports UART/USART communication and an eight-source interrupt architecture. Two software-selectable power-saving modes, Idle and Power-down, are available. The Flash endurance is rated at 10,000 write/erase cycles.
Packaged in a 44-pin PLCC with J-Lead packaging, the AT89C55WD-24JU is intended for surface-mount assembly and requires no external oscillator when using the internal clock. The operating temperature range is -40°C to 85°C, making it suitable for industrial applications.
It operates from 4V to 5.5V.
It comes in a 44-pin PLCC (J-Lead) surface-mount package (supplier package 44-PLCC, 16.6x16.6mm).
The operating temperature range is -40°C to +85°C.
Yes, it is RoHS3 compliant per the manufacturer page.
It uses an 8051-compatible 8-bit core.
It has 20KB of reprogrammable Flash memory (20K x 8) with 10,000 write/erase cycles per the datasheet.
Yes, it includes a hardware watchdog timer.
