The picture below shows the ‘ISPnano-MUX8’ programmer…
Sequential multiplexing…
The sequential multiplexing approach supports programming of only one UUT at a time which means
that the programming time for a panel of e.g. 2 / 4 / 8 PCBs which will be significantly longer than if an
individual programmer was used for each channel. However, for many programming applications, the
programming time is very short anyway or is not the most important factor in the system, so this
multiplexed approach would work very well.
Multiplexing of programming signals…
The programming signals for each programming channel are multiplexed using high-quality analogue
switches to each UUT in turn. The power signals (TVCC, VPP and EXT-VCC) are all individually
switched to each UUT using relays. This approach allows the power to each UUT to be individually
controlled and measured and means that only a single UUT is then powered on at any point in time
making it possible to detect short circuits and other faults for an individual UUT.
Operating the programmer in ‘Standalone Mode’….
The ISPnano-MUX programmers are capable of operating in 'Standalone Mode' where any one of
64 independent 'Programming Projects' can be executed via a remote command. The programmer
also features a 4-wire TTL Remote Control interface making it ideal for interfacing to any ATE or In-
Circuit Tester (ICT). A special 'Start Signal' can be used to detect when a Test Fixture lid has been
closed and thereby automatically start a programming operation.
