CY14B101PA is a 3V (2.7V-3.6V) device so keeping VCC=3.3V is alright.
As long as logic levels on the nvSRAM's IO pins are maintained , device will work without any issue. When connecting a 5V IO logic standard with 3V logic IO standard, the VIL, VIH and VOL, VOH specs must be properly verified for its compatibility for the logic leveles between the two devices. If logic levels falls within device range, devices will work without any issue.
As long as VCC stays within 2.7V to 3.6V, device will work properly. 3.2V is ok for the nvSRAM.
I dont see any issue with this configuration. If you are anticipating any spific condition where you think it may be an issue then please let me know, I can review and let you know the impact if any. Otherwise it ok to use nvSRAM in above configuration as you have mentioned.
