Introduction
864 is a universal programmer that supports programmable
integrated circuits or devices manufactured in various
technologies. Powerful internal pin-driver electronics controls
logic levels, pull-up/pull-down, clock, ground, one power supply
and two programming supplies and is able to read all 48 pins
independently. This advanced design gives 864 the ability to
handle almost every programmable device in DIL package up
to 48 pins without any adapters and/or family modules. This
design philosophy allows B+K PRECISION to easily add new
devices to the device list, giving you the freedom to implement
the optimum device in your designs.
864 is also a tester of TTL/CMOS logic circuits and various
memories. Furthermore, it can generate user-definable test
pattern sequences. 864 is a true universal and a true low-cost
programmer, providing the best "value for money" in today's
market.
864 works with the IBM PC Pentium compatible or higher,
portable or desktop personal computers. No special interface
card is required to connect to the PC since 864 uses the
standard parallel printer port. The 864 control program also
supports bi-directional protocols for the parallel connection to
the PC printer port providing fast and reliable communication
speed.
The programmer has on-board intelligence and is controlled by
powerful Microcontroller system and support devices. 864 has
been designed for multitasking operating systems and is
able
to
perform
time-critical
programming
sequences
independently of the PC operating system status and without
being interrupted by any other parallel process running on the
PC. Consequently, 864 works without any problem on systems
running Windows 95/98/Me/NT/2000/XP.
864 performs device insertion test (wrong or backward
position) and contact check (poor contact pin-to-socket) before
it programs any device. These capabilities, supported by
current limit protection and signature-byte check, help prevent
chip damage due to operator error.
Built-in protection circuits help prevent damage of the target
device due to mains supply fluctuations, communication errors
or if the PC operating system fails. In the event of such errors
the 864 performs independently of the PC exactly specified
special sequences so that the target device remains intact. 864
performs self test (diagnostic tests), including verification of
pin-driver voltage/level, for accurate timing of the signals
