Note: (4) Due to the inclusion of the decoder IC on board the module the WE and CE write controlled timings will vary. When utilizing the
CE controlled write operation all the hold timings must be extended by the worst case propagation delay of the decoder. For a
WE controlled write operation CE must be a minimum 125ns to accommodate the additional setup time required.
