The EMP-11 programmer is our first low-cost offering with Windows Support. With a low voltage capability like the EMP-30 it gives you the ability to program newer chips, but being the same size as the EMP-10 makes this unit extremely portable. Supporting more than 2,100 devices, including EPROMs, FLASH, 8051-style micros, Microchip PICs, and hundreds of other specialty devices the EMP-11 is also a great cost alternative to the EMP-20. To change device families, simply change or flip any one of the four Family Modules. Relays and discrete DAC-controlled analog drivers provide power and ground connections.


The EMP-11 uses the same parallel port I/O scheme as the EMP series programmers, for an extremely fast communication.

The EMP-11 is extremely portable; since it doesn't occupy a bus card in your PC, you can pack it up and take it with you anytime you wish. At only 1.5"x5"x8", with a 2" high power transformer, the EMP-11 fits into a briefcase or toolbox with ease. The programmer, parallel cable, transformer, and Family Modules, together weigh in at less than three pounds!


  • The EMP-11 carries a 1 year warranty on all parts and labor, and a 30 day money-back guarantee (restocking fee may apply)
  • The EMP-11 is static-protected at the ZIF Socket, Family Module socket, parallel port, and power connector. The static protection on the parallel port also protects the parallel port on the EMP-11 from the 12 volts of a serial port.
  • It's case is made of tough .125" thick ABS plastic.
  • There is almost nothing to wear out on the EMP-11; no fan, not even a power switch. The only moving part on the EMP-11 is the Family Module, and that only moves when you switch device families.
  • Compliant, for sale into the European Community.


Family modules are not an entirely new idea. They have been used in other programmers from time to time, to inexpensively route power and ground to the device. When you're programming devices fairly slow, then straight, slide-in connectors are just fine. However, the EMP-10 and EMP-20 program at speeds near the theoretical maximums of some devices, so the digital signals traveling to the device must be clean, and the power and ground lines must be solid. Slide-in connectors can experience noise problems and higher resistance. The connectors that the EMP-10 and EMP-20 use are the same snap-in SIMM connectors that you may have holding the DRAM in your PC.

The purpose of Family modules is to allow us to use a few high quality pin drivers, instead of using a cheaper pin driver on each pin on the ZIF socket. This translates to cleaner, more manageable waveforms, at a much lower price.


To use the EMP-11, you must have the following:

  • Operating System: An IBM-Compatible PC, Windows 95 or above, with 16Mb of RAM
  • Hard Drive Space: At least 40Mb of free space
  • Interface: A standard parallel port
  • Power: 12-16 Volts @ 1 Amp, AC or DC


  • A standard parallel port cable
  • A 40-Pin ZIF socket for DIP parts
  • An AC 110V transformer ( a 220V transformer at additional cost is available upon request)
  • All Family modules are included with the EMP-11, in a small carrying wallet
