Atmel 8051 AT89S52 AVR 40 Pin DIP Microcontroller

The Atmel 8051 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 industry-standard 89C51 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 AT89S52 is a powerful microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications.

Features:

• 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.
