Product Overview

The AT89C51RC2-3CSUM is a 8-bit High-performance Microcontroller with 32kB flash. It retains all features of the 80C52 with 256 bytes of internal RAM, a 9-source 4-level interrupt controller and three timer/counters. It features a programmable counter array, an XRAM of 1024 bytes, hardware watchdog timer, keyboard interface, SPI interface, versatile serial channel that facilitates multiprocessor communication (EUART) and a speed improvement mechanism (X2 mode). We recommend implementing an external brown-out to prevent any flash/EEPROM corruption during power-on or power-off. The AT89C51RC2 is a high-performance flash version of the 80C51 8-bit microcontrollers. It contains a 16k or 32kB flash memory block for program and data. The flash memory can be programmed either in parallel mode or in serial mode with the ISP capability or with software. The programming voltage is internally generated from the standard VCC pin.
  • 80C52 Compatible
  • Variable length MOVX for slow RAM/peripherals
  • ISP (In-System Programming) using standard VCC power supply
  • Boot ROM contains low level flash programming routines and a default serial loader
  • High-speed architecture
  • On-chip 1024-byte expanded RAM (XRAM)
  • Keyboard interrupt interface on port P1
  • SPI interface (master/slave mode)
  • 8-bit Clock prescaler
  • Improved X2 mode with independent selection for CPU and each peripheral
  • Programmable counter array 5 channels
  • Asynchronous port reset
  • Full duplex enhanced UART
  • Dedicated baud rate generator for UART
  • Low EMI (inhibit ALE)
  • Hardware watchdog timer (one-time enabled with reset-out)
  • Power control modes - Idle mode, power-down mode, power-off flag
  • Commercial (0 to +70°C) and industrial (-40 to +85°C) temperature ranges
