Product Overview

The AT89C2051-12PU is a 8-bit low-voltage, high-performance CMOS Microcomputer with 2kB of flash programmable and erasable read-only memory (PEROM). The device is manufactured using Atmel's high-density non-volatile memory technology and is compatible with the industry-standard MCS-51 instruction set. By combining a versatile 8-bit CPU with flash on a monolithic chip, the Atmel AT89C2051 is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications. The AT89C2051 provides the following standard features, 2kB of flash, 128 bytes of RAM, 15 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt architecture, a full duplex serial port, a precision analogue comparator, on-chip oscillator and clock circuitry. In addition, the AT89C2051 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes.
  • Compatible with MCS®-51 products
  • 10,000 Write/erase cycles endurance
  • Two-level program memory lock
  • 128 x 8-bit internal RAM
  • 15 Programmable I/O lines
  • Two 16-bit timer/counters
  • Six interrupt sources
  • Programmable serial UART channel
  • Direct LED drive outputs
  • On-chip analogue comparator
