Our AT89C2051 and AT89C51 programmers date from the 1990's - they are very straightforward, work perfectly well under linux or windows, and we still sell replacements. To help our previous customers we offer full technical info

Erase, Program and verify an AT89C2051 in one easy operation!

Introduction to 8051 Programming With AT89C2051 (Guest Starring: Arduino): The 8051 (also known as MCS-51) is an MCU design from the 80's that remains popular today. Modern 8051-compatible microcontrollers are available from multiple vendors, in all shapes and sizes, and with a wide range of peripherals. In this instructab.

PG2051 - A Programmer for the Atmel AT89C2051, from AirBorn Electronics

The AT89C2051 is a 20 pin 8051 compatible microprocessor (including serial port) with 2k of FLASH memory, available from Atmel (see www.atmel.com). The PG2051 erases, programs, and verifies AT89C2051 chips in 6 seconds. As the AT89C2051 devices are FLASH, they can be reprogrammed as often as needed.

The PG2051 is driven by sending it a (standard) Intel hex file through its serial port. This means it can be driven by any operating system - all that is necessary is that the host has a serial port to send the data to the programmer (at 9600 baud) - the programmer will do the rest.

The programmer features a test switch which allows the owner to check if an AT89C2051 is blank, working, programmed or failed in just one second - without needing the PC connected. Daag rajesh khanna full movie free download.

OPERATION:

The PG2051 is a development programmer for the ATMEL AT89C2051. The AT89C2051 programmer is fast, small and simple to use. 2051

The programmer may be connected to a PC or other host by a serial cable. The data to be downloaded to the programmer is transmitted in Intel Hex format. The programmer will erase & program, verify, write protect and security protect as it receives the file, according to the settings on its Dip switches.

In normal use device programming consists of:
Insert an 89C2051	- (Manual Test if desired)	Mode COM1:9600,N,8,2
Download intel hex file	- (Causes programming)	Copy Myfile.hex COM1
Watch LEDs	- (Indicates success)

The PG2051 can be used stand-alone by inserting an 89C2051 and operating the Manual test switch, in this mode it indicates Tested, Blank and Verified checksum conditions.

2021 Programming Language Trends

The AirBorn Electronics programmer described here connects to a Serial port, works under any operating system, and programs in 6 seconds by just copying the hex file to the COM port.
There is also a programmer design available from Atmel that you can build yourself - although it does not share these features.
