AT89S52 8-bit Microcontroller

Fr 7,000.00

AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the indus- try-standard 80C51 instruction set and pinout.



  • It is a high-performance CMOS microcontrollers with Flash Technology
  • The unit operates at a wide range of 4 – 5.5 volts, so it is a low power IC.
  • The device supports In-system Programming both page and byte mode for the Flash memory.
  • The operational frequency of CPU is up to 33MHz but can be altered for saving energy.
  • The module has a quick programming time with 10,000 read/write cycles.
  • The Random Access memory is organized in 256×8 bits.
  • The serial communication takes place through a full duplex UART module.
  • It comes with a reset option, three 16-bit timers and eight interrupts.
  • AT89S52 has two power modes, i.e., idle mode in which  stops processing unit stops while other peripheral keep working and power-down mode that halts oscillator and other functions and save RAM contents.


  • Multiple DIY Projects
  • Very good choice if you are learning ATmel
  • Projects requiring Multiple I/O interfaces and communications
  • Replacement for Arduino Module
