Product Overview

The AT89C55WD-24PU is a 8-bit low-power High-performance CMOS Microcontroller with 20kB of flash programmable read only memory and 256 bytes of RAM. The device is manufactured using Atmel's high-density non-volatile memory technology and is compatible with the industry standard 80C51 and 80C52 instruction set and pinout. The on-chip Flash allows the program memory to be user programmed by a conventional non-volatile memory programmer. By combining a versatile 8-bit CPU with flash on a monolithic chip, the Atmel AT89C55WD is a powerful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications. The AT89C55WD provides the following standard features 20kB of Flash, 256 bytes of RAM, 32 I/O lines, three 16-bit timer/counters, a six-vector, two-level interrupt architecture, a full-duplex serial port, on-chip oscillator and clock circuitry.
  • Compatible with MCS®-51 products
  • 20kB Reprogrammable flash memory
  • 10,000 Write/erase cycles endurance
  • Three-level program memory lock
  • 256 x 8-bit Internal RAM
  • 32 Programmable I/O lines
  • Three 16-bit timers/counters
  • Eight interrupt sources
  • Programmable serial channel
  • Low-power idle and power-down modes
  • Interrupt recovery from power-down mode
  • Hardware watchdog timer
  • Dual data pointer
  • Power-off flag
