UEP 50
Multiprogramming System - Universal EPROM Programmer 48 pin


Find out how to use BeeProg programmer in High Volume Production Application.

The UEP 50 programmer is extremely fast and totally reliable universal programmer that support 30.008 chips by actual version of software (March. 2014).

The UEP 50 programmer is basically intended as powerfull engineering programmer, useable also as a single-site programmer in volume production.

What about multiprogrammer and requirements for multiprogramming?

Check please the application note optimal solution for multiprogramming about multiprogramming basics.

By operating multiple UEP 50 programmers simultaneously you can use them in high volume production environment - other words, using more UEP 50 programmers you can get a universal, up to 4 programming sites multiprogrammer with 48-pin DIP ZIF sockets, connects to PC by USB port. It is important to mention, there is a concurrent multiprogramming system - each programmer works independently and each programmer can program different chip, if necessary.

Benefits of the UEP 50 multiprogramming solution:

  1. In generally, the UEP 49+ multiprogramming system take advantage of all benefits of UEP 50 programmer.


  2. BeeProg programmer is a high performance universal programmer supporting 30.008 chips and growing. We add new devices at a rate of about 4,000 devices/year and new software update is released monthly at least. Most gang programmers have limited number of supported devices, because they haven't universal hardware. It also takes very long time for device update and the cost could be high. The abilities to add new devices for BeeProg multiprogramming system is as unlimited because of BeeProg's universal hardware and the software updates are free of charge.


  3. BeeProg programmer is extremely fast. It is faster than most gang programmers. Therefore the multiprogramming solution based on the UEP 50 programmer can program more chips in a day than a traditional gang multiprogrammer.


  4. Asynchronous (Concurrent) programming is more efficient than the synchronous (gang) programming of traditional gang programmers. In the concurrent multiprogramming mode each site operate independently. The programming starts as soon as a device is inserted into ZIF socket. Before the last device is loaded, the first device is already programmed and ready for removal. Operator is busy removing and inserting chips, so both the operator and programmer are running continuously at maximum efficiency. In standard gang programmer operation, the operator is idle while chips are being programmed, and the programmer is idle while chips are being removed and new chips inserted. Therefore for the medium programming times you can easily do the job of an 8-gang programmer with 2-4 of UEP 50 programmers.


  5. We provide a wide range of socket converters (programming adapters), therefore there exist none problem to program also chips in the special packages. The very big sockets can be supported, such as PLCC84, TQFP176, etc. Most gang programmers are designed with narrow spacing between sockets.


  6. The special software (PG4UWMC = PG4UW Multiprogramming control) is available for controlling of the BeeProg programmers in the UEP 50 multiprogramming mode. There is used a project file to control the BeeProg multiprogramming. Project file contains user data, chip programming setup information, chip configuration data, auto programming command sequence, etc. Therefore the operator error is minimized, because the project file is normally created and proofed by engineering and then given to the operator. The optional protected mode can be set for project file to avoid a unwanted changes of the project file.

PG4UW Multiprogramming control software is standard part of PG4UW software delivery.


  1. Hands-free operation. Asynchronous (concurrent) operation allows a chip to begin programming immediately upon insertion of a chip. The operator merely removes the finished chip and inserts a new chip. Operator training is therefore minimized.


  2. Service is easy. If one unit breaks down, the rest of the system is still running while having the defective unit serviced. You cannot do this with standard gang multiprogrammers.

Recommendations for BeeProg multiprogramming system:

  • use enough powerful PC, min. Pentium 4; 1GHz (2GHz recommended)
  • use OS Microsoft Windows NT/2000/XP (XP recommended)
  • use external 1/4 USB HUB rater, than connect the programmers to the USP port of the PC
  • we've tested many USB hubs and we got best result with the Cypress chips based USB hubs. If you have doubts, we can provide suitable USB hub, just ask.
  • don't use USB 1.1 interface/hub/components
