Frequently asked questions
We are running a 600 MHz memory controller — does the 33 MHz step to 633 MHz on this part require timing re-validation?
Yes. The 633 MHz clock sits 5.5% above the 600 MHz variant. Setup and hold margins at the memory controller receiver shrink proportionally, and the 1.7V to 1.9V supply band leaves less droop headroom than a wider rail would. A timing margin review against your FPGA or ASIC controller's datasheet is the safe step before committing the BOM line.
Is the CY7C1265XV18-633BZXC a guaranteed drop-in for this part?
Not on depth alone. The CY7C1265XV18-633BZXC matches on clock (633 MHz), supply voltage (1.7V), package, and temperature grade — but it is organized as 512K by 36 versus this part's 1M by 36. A board designed for 1M depth will see address wrapping on the lower-density part, which is a functional failure, not a silent swap. Confirm the memory depth your controller expects before using the CY7C1265 as a source.
