CION Module/DIMM240 boundary scan I/O digital module is serially controlled via TAP to CION ASIC chips. Enables testing of all signal and voltage supply pins of JEDEC Std. compliant DIMM240 sockets for DDR2-SDRAM. Is plugged into a respective socket, whereby the interface stages’ voltages are adapted automatically. Several boards of the same or different types can be cascaded in a daisy chain configuration. All channels can be independently switched as Input/Output/Tristate. Provides special safety mechanisms. Is supported by all JTAG/boundary scan controllers of ScanBooster and Scanflex families, as well as the Cascon integrated boundary scan software platform system.
