TriBoard Information
3.1
Soldered board
TriBoard TC3X4T V1.0 is the soldered board and will be available only with usable devices. Please see also chapter
.
3.2
Socketed board
TriBoard TC3X4T TH V1.0 is the socketed board and will be available in two assembly options:
– For device with PMSLE module and without PMS module (TC334 and TC324)
– For device with PMS module and without PMSLE module (TC364)
Difference between this two module is, that the PMSLE use a Switch Capacitor Regulator for the core voltage
generation which need only an external capacitor (see schematic C518, no external coil, no external p+n mosfet).
The PMS module use a Step-down Regulator which need an external p+n mosfet (see schematic Q506) and an
external coil (see schematic L503). To differentiate between the two boards have a look to C518. If assembled
then TC334 and TC324 can be used otherwise only TC364.
If you get the board with TC364 and you will use the board with TC334 or TC324 then you must remove R528, R529
and R523, assemble R541 and R542 with a resistor 0R size 0603 and assemble C518 with a capacitor 1µF size 0603
(e.g. CGA3E1X7R1E105K) otherwise the TC334 and TC324 will not work.
If you get the board with TC334 or TC324 and you will use the board with TC364 then you must remove R541, R542
and C518 and assemble R528, R529 and R523 with a resistor 0R size 0603.
The mentioned components are red marked in the following
