Basic Concepts of Micro Controller Programming- AT89c 2051 Microcontroller Programmer
This is Simple to use & low cost, yet powerful flash microcontroller programmer for the Atmel 89 series. It will Program, Read and Verify Code Data, Write Lock Bits, Erase and Blank Check. All fuse and lock bits are programmable. This programmer has sensible onboard firmware and connects to the serial port. It can be used with any type of computer and requires no special hardware. All that is needed is a serial communication port which all computers have.
All devices have sign bytes that the programmer reads to automatically identify the chip. No need to select the device type, just plug it in and go. All devices also have a number of lock bits to provide various levels of software and programming protection. These lock bits are fully programmable using this programmer. Lock bits are helpful to protect the program to be read back from microcontroller only allowing cancel to reprogram the microcontroller.
The programmer combines to a host computer using a standard RS232 serial port. All the programming ‘knowledge’ is built into the programmer so you do not need any special hardware to run it. The programmer comes with window based software for easy programming of the devices.
Atmel AVR Micro Programme

The programmer is fitting for programming the three popular 20-pin Atmel processors, the 89C1051, 89C2051 and the new 89C4051 with 4 k of program memory. It is a new arrival in the Atmel family of powerful yet inexpensive MCS51-compatible microcontrollers with flash memory (PEROM): the 89C4051 boasts 4 kB
of program memory. And also the program memory capacity all members of the family has the features:– 128 bytes RAM– 15 I/O port bits– 2 16-bit timer/counters– Interrupt architecture with two priorities and five vectors–and it is Programmable full-duplex serial port– Precision analog comparator– Integrated clock/oscillator circuit.
