The EMP-21 Device Programmer:
$649.95 retail Buy
June 17,2002

The next generation in device programmers is here. The
EMP-21 is the world’s first universal device programmer that
uses both USB and the Parallel Port. With a starting base of
over 4000
devices supported and Windows based software this programmer is
a great renovation of the EMP-20. While utilizing the USB port will
increase transfer times, the choice whether to connect to your PC
via either USB or by the Parallel Port, is completely up to you.
Needham’s all new “automated one touch” system allows you to blank
check, erase, program, verify or any combination of these functions
with the ease of pushing a button.The low profile, lightweight
design of the EMP-21 makes it ideal for any desktop or briefcase,
proving useful for programming devices in the field. Plus the
comparatively inexpensive cost of the EMP-21 lends well to a wide
variety of budgets and with the absence of a fan or power switch,
wear and tear is almost nonexistent.

SPEED
The EMP-21 uses the new USB I/O
scheme, so transfer times are greatly improved.

PORTABILITY

The EMP-21 is extremely portable, you can pack it up and take it
with you anytime you wish. At only 10 1/2" x 6 1/2" x 1 1/4", with a
2" high power transformer, the EMP-21 fits into a briefcase or
toolbox with ease. The programmer, parallel and usb cable,
transformer, and Family
Modules, together weigh in at less than five pounds!

STABILITY

The EMP-21 carries a 1 year warranty on all parts and labor,
and a 30 day money-back guarantee (restocking fee may apply)

The EMP-21 is static-protected at the ZIF Socket, Family Module
socket, parallel and usb port, and power connector. The static
protection on the parallel port also protects the parallel port on
the EMP-21 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-21; no fan, not
even a power switch. The only moving part on the EMP-21 is the
Family Module, and that only moves when you switch device
families.

FAMILY
MODULES

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.
