Atmel Microcontroller AT89S51 MCU (8-Bit)

The AT89S51 is a low-power, high-performance CMOS 8-bit microcontroller with 4K bytes of In-System Programmable Flash memory. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 instruction set and pinout. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with In-System Programmable Flash on a monolithic chip, the Atmel AT89S51 is a powerful microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications.

 In addition, the AT89S51 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 oscillator, disabling all other chip functions until the next external interrupt or hardware reset.

  5. Three-level Program Memory Lock
  6. 128 x 8-bit Internal RAM
  7. 32 Programmable I/O Lines
  8. Two 16-bit Timer/Counters
  9. Six Interrupt Sources
  10. Full Duplex UART Serial Channel
  11. Low-power Idle and Power-down Modes
  12. Interrupt Recovery from Power-down Mode
  13. Watchdog Timer
  14. Dual Data Pointer
  15. Power-off Flag
  16. Fast Programming Time
  17. Flexible ISP Programming (Byte and Page Mode)
