PC Compatible serial
Programs security bits, reads signatures, verifies

The Atmel AT89C51, AT89C52, AT89C55, AT89LV51, AT89LV52 and AT89S8252 are FLASH memory CPUs compatible with the 8051 instruction set. The PG8951 erases, programs and verifies these devices in 3 seconds per kilobyte of code written. As the devices are FLASH, they can be reprogrammed as often as needed.

The PG2051 may be connected to a PC or other host by a serial cable. The programmer interface is PC serial compatible, operates at 9600 Baud, and accepts standard Intel Hex files.

PG2051 - A Programmer for the Atmel AT89C2051

Order form for AT89C2051 programmer

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 may be connected to a PC or other host by a serial cable. The programmer interface is PC serial compatible, operates at 9600 Baud, and accepts standard Intel Hex files.

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.
