Introduction
844A is next member of new generation of Windows
95/98/Me/NT/2000/XP based B+K PRECISION universal
programmers. Programmer is built to meet the demands of the
development labs and field engineers to universal, but portable
programmer.
844A is a small, fast and powerful programmer of all kinds of
programmable
devices.
Using
build-in
in-circuit
serial
programming (ISP) connector the programmer is able to
program ISP capable chips in-circuit.
844A isn't only a programmer, but also tester of TTL/CMOS
logic ICs and memories.
It provides a very competitive price and excellent hardware
design for reliable programming. Great "value for money".
Very fast programming due to high-speed FPGA driven
hardware and support of IEEE1284 (ECP/EPP) high-speed
parallel port. Surely faster than competitors in this category.
844A interfaces with the IBM PC, AT or above, portable or
desktop personal computers through any standard parallel
(printer) port (no special interface card needed). Therefore you
can take programmer and move it to another PC without
assembly/disassembly of PC.
844A
has
40
powerful
TTL
pindrivers
provide
H/L/pull_up/pull_down and read capability for each pin of
socket. Advanced pindrivers incorporate high-quality high-
speed circuitry to deliver signals without overshoot or ground
bounce for all supported devices. Pin drivers operate down to
1.8V so you'll be ready to program the full range of today's
advanced low-voltage devices.
The programmer performs device insertion test (wrong
device position in socket) and contact check (poor contact pin-
to-socket) before it programs each device. These capabilities,
supported by signature-byte check help prevent chip damage
due to operator error.
Programmer's hardware offers enough resources for self test,
that control program is any time be able to check pindrivers,
present and correct level of all voltages, check the timing and
communication between programmer and PC.
