A question was asked yesterday about the scope of work/complexity of a customer moving from an ArcticLink III BX design to an ArcticLink III VX design. This chart provides an easy primer (click to embiggen)
As you can see, the scope of work is not great. The pinouts are identical, meaning there are no (read: zero) board changes required. Board changes are costly, time-consuming, and can be an expensive hurdle to overcome. The identical footprint and pinout of the BX and VX allows a change of device without any of these hurdles.
At a driver level, the existing BX driver is re-used, with additional code added to set and modify the VEE/DPO registers on the VX devices. As with all CSSP engagements, QuickLogic does provide the driver to customers should they choose, with VEE/DPO settings having been agreed upon during a calibration session with the customer.
All this adds up to the BX being a great starting point, with an immediate and easy upgrade path to a VEE and DPO-enabled ArcticLink III VX device with no risk.
