Introduction
844USB is next member of new generation of Windows 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.
844USB 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. 844USB isn't only a programmer, but also a static
RAMs tester.
844USB provides very competitive price with excellent hardware design for reliable
programming. Nice "value for money" in this class.
844USB provides very fast programming due to high-speed FPGA driven hardware and USB
2.0 full speed port.
844USB interfaces with the IBM PC Pentium compatible or higher, portable or desktop
personal computers through USB port , what is important for new, LPT-port-less computers
(notebooks for example).
844USB 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.
844USB programmer performs programming verification at the marginal level of supply
voltage, which, obviously, improves programming yield, and guarantees long data retention.
844USB programmer is driven by an easy-to-use control program with pull-down menu, hot
keys and on-line help. Selecting of device is performed by its class, by manufacturer or
simply by typing a fragment of vendor name and/or part number.
Standard device-related commands (read, blank check, program, verify, erase) are boosted
by some test functions (insertion test, signature-byte check), and some special functions
(autoincrement).
All known data formats are supported. Automatic file format detection and conversion during
load of file.
The rich-featured
autoincrement function enables to assign individual serial numbers to
each programmed device - or simply increments a serial number, or the function enables to
read serial numbers or any programmed device identification signatures from a file.
