ZL7PRG PCB - circuit board of the '51 family microcontroller programmer with Flash memory in DIP20 / 40 enclosures

Printed circuit board programmer ZL7PRG.
Using the ZL7PRG programmer, you can program most of the '51 family of microcontrollers with flash memory and EPROM delivered in 20 or 40 lead casings. Programmer performance was tested on the following systems: D87C51, D87C52, AT89C51, AT89S51, AT89C51RC, AT89C52, AT89S52, AT89S53, AT89C55, AT89C55WD, AT89C1051, AT89C1051U, AT89C2051, AT89C4051 and AT89S8252. For programming microcontrollers in 20-pin casings, an adapter-grommet is necessary.
The programmer's operation is controlled by a user-friendly software that can work under the care of Windows operating systems (including NT, 2000 and XP). One of the advantages of the control program is the lack of necessity to install it, which makes the ZL7PRG easily portable and can also be used in maintenance work. The perfect complement to the laboratory for readers of the book "Microcontrollers 8051 in practice".
