Product Overview

The AT89C5131A-RDTUM is a 1-chip 8-bit high-performance flash version of the 80C51 Microcontroller with full-speed USB functions. This device retains the features of the Atmel 80C52 and adds 1024 bytes of on-chip expanded ERAM, dual data pointer, 16-bit up...
  • 80C52X2 Core (6 clocks per instruction)
  • 16/32kB On-chip flash EEPROM in-system programming through USB
  • 3kB Flash EEPROM for bootloader
  • 1kB EEPROM data - Byte and page (128 bytes) erase and write
  • 1024-byte On-chip expanded RAM (ERAM)
  • Integrated power monitor (POR/PFD) to supervise internal power supply
  • USB 1.1 and 2.0 Full speed compliant module with interrupt on transfer completion
  • 100ms to 3s at 8MHz Programmable hardware watchdog timer (one-time enabled with reset-out)
  • Keyboard interrupt interface on port P1 (8 bits)
  • 400kBps TWI (Two Wire Interface)
  • SPI interface (master/slave mode)
  • 34 I/O pins
  • 4 Direct-drive LED outputs with programmable current sources (2-6-10mA typical)
  • 4-level Priority interrupt system (11 sources)
  • Idle and power-down modes
  • 0 to 24MHz On-chip oscillator with analogue PLL for 48MHz synthesis
  • Industrial temperature range
