• 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.

Applications

• Multiple DIY Projects


• Very good choice if you are learning ATmel


• Projects requiring Multiple I/O interfaces and communications


• Replacement for Arduino Module
