Product Overview

The AT89C55WD-24JU is a low-power, high-performance 8-bit CMOS Microcontroller with 20kB of flash programmable read only memory and 256byte of RAM. The device is manufactured using high-density nonvolatile memory technology and is compatible with the industry standard 80C51 and 80C52 instruction set and pin out. The on-chip flash allows the program memory to be user programmed by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with flash on a monolithic chip, the AT89C55WD is a powerful microcomputer which provides a highly flexible solution.
  • Compatible with MCS®51 products
  • 10,000 Write/Erase cycles Endurance
  • 0 to 33MHz Fully static operation
  • Three-level program memory lock
  • 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
