Product Overview

The AT89C51ED2-RLTUM is a 1-chip 8-bit high performance CMOS Flash version of the 80C51 CMOS Microcontroller with a 64kB flash memory block for code and for data and 2048 bytes of EEPROM for non-volatile data storage. The flash memory can be programmed in parallel or serial mode using the ISP capability or using software. The programming voltage is internally generated from the standard VCC pin. This device retains all of the features of the Atmel 80C52 and adds a programmable counter array, 1792 bytes of XRAM, a hardware watchdog timer, SPI interface, keyboard, a more versatile serial channel that facilitates multiprocessor communication (EUART) and a speed improvement mechanism (X2 Mode).
  • 80C52 Compatible - 8051 instruction compatible
  • Integrated power monitor (POR/PFD) to supervise internal power supply
  • ISP (In-System Programming) using standard VCC power supply
  • 2048-byte Boot ROM contains low level flash programming routines and a default serial loader
  • High-speed architecture
  • 64kB On-chip flash program/data memory
  • On-chip 1792-byte expanded RAM (XRAM)
  • On-chip 2048-byte EEPROM block for data storage (AT89C51ED2 Only)
  • 100K Writing cycles
  • Dual data pointer
  • Variable length MOVX for slow RAM/peripherals
  • Improved X2 mode with independent selection for CPU and each peripheral
  • Keyboard interrupt interface on port P1
  • SPI interface (master/slave mode)
  • 8-bit Clock prescaler
  • 16-bit Programmable counter array
  • Asynchronous port reset
  • Full-duplex enhanced UART with dedicated internal baud rate generator
  • Low EMI (inhibit ALE)
  • Hardware watchdog timer (one-time enabled with reset-out), power-off flag
