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 RAM

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,.

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.
