AT89S51-AT89S52 Development Board Programmer
Introduction 89S51/52  Development Board
The 89S51/52  Development Board and programmer can be used to develop and program 89s52 microcontroller. Low cost 89S52 development board is easily available in the market and it is a very useful tool to develop applications for students. This board has so many hardware features. The cost of 89S52 development board is very low. Low cost 89S52 Development Board is a sophisticate development board equipped with so many useful hardware. It can be connected directly to the laptops or computer with the USB cable and firmware can be updated instantly.
Atmel 89S51/52 microcontroller has 8KB inbuilt flash storage memory and comes with the 11.0592 crystal. This is the in system programmable can be programmed inside the development board so it is not removed from hardware. Interfacing 89s52 Microcontroller with Buzzer, RTC, EEPROM and LCD provision has been already given with its connectors. Board can be used to develop projects 89S51, 89S52 for students. AT89S52 development kit is full -featured development programmer board for the ATMEL AT89S52  microcontrollers and compatible with 8051 Microcontrollers which use RISC core. It has a 40 pin DIP microcontroller which is the heart of the development board.
