LabProg+
verification of pin-driver voltage/level, for accurate timing of the
signals applied to the target device and for reliable
communication with the PC.
LabProg+ incorporates optimal PCB design criteria to minimize
unwanted effects at the pins of the target socket (such as
ground-bouncing and supply/programming voltage glitches). All
the inputs of the LabProg+, including the socket, are protected
against ESD and whilst inserted the target device is also
protected against ESD damage.
LabProg+ performs programming verification at the marginal
level of supply voltage which, obviously, improves
programming yield and guarantees long data retention.
The LabProg+ is driven by an easy-to-use, control program
with pull-down menus, hot keys and on-line help. You can
select the target device by its class, by manufacturer or simply
by typing a fragment of vendor name or part number. Besides
the standard device-related commands (blank check, read,
program, verify) have been implemented some test functions
(illegal bit test, insertion test), and some special functions
(production mode - start the action immediately after insertion
of device into ZIF socket). The control program permits data
manipulation within the buffer and between the buffer and
associated files, and performs automatic file format detection
and conversion.
The control program provides an auto-increment function
that enables you to assign individual serial numbers to each
programmed device, this function simply increments a serial
number in the buffer each time a new device is inserted in the
socket. Furthermore, the function enables the operator to read
serial numbers and/or any programmed device identification
signatures from a file.
Various socket converters are available for the LabProg+,
DIL to PLCC, DIL to PSOP, DIL to SOIC, DIL to TQFP and DIL
to TSOP. Software controlled pin-swapping capability together
with universal converters are what give the LabProg+ the
ability to program the target device in any package type. For
example, just one DIL44 to PLCC44 converter will allow the
LabProg+ to handle any PLCC44 target device in the current
device list. Most devices with more than 48 pins require a
simple adapter usually available from ELNEC or easily built by
the user from information provided in the file "adapters.txt"
included with the control program.
It is important to remember that in most cases new devices
require only a software upgrade since the LabProg+ has 48
true pin drivers, which can perform as required under program
