Product Overview

The AT89S2051-24SU is a low-voltage, high-performance 8-bit CMOS Microcontroller with 2kB of In-system programmable (ISP) flash program memory. The device is manufactured using high-density nonvolatile 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 AT89S2051 is a powerful microcontroller which provides a highly-flexible solution to many embedded control applications. It is designed with static logic for operation down to zero frequency and supports two software-selectable power saving modes. The idle mode stops the CPU while allowing the RAM, timer/counters, serial port and interrupt system to continue functioning. The power-down mode saves the RAM contents but freezes the disabling all other chip functions until the next external interrupt or hardware reset.
  • Compatible with MCS®51 products
  • 0 to 24MHz Fully static operation
  • Two-level program memory lock
  • 256 x 8-bit Internal RAM
  • 15 Programmable I/O lines
  • Two 16-bit timers/counters
  • Six interrupt sources
  • Programmable serial UART channel
  • Direct LED drive outputs
  • On-chip analog comparator with selectable interrupt
  • 8-bit PWM (Pulse-width modulation)
  • Low power idle and power-down modes
  • Brownout reset
  • Enhanced UART serial port with framing error detection and automatic address recognition
  • Internal power-on reset
  • Interrupt recovery from power-down mode
  • Programmable and fuseable x2 clock option
  • Four-level enhanced interrupt controller
  • Power-off flag
  • Flexible programming (byte and page modes)
  • User serviceable signature page (32Byte)
