This application note provides details for migrating from the CY14B256L/STK14D88 parts to the CY14B256LA.
Cypress CY14B256LA is a 3 V, 256 Kbit (32 K x 8) nvSRAM in 0.13 u technology. This part is a pin to pin functional equivalent of CY14B256L/STK14D88 (0.25 u) and is superior in endurance and data retention. However, the older technology part has a lower capacitor range for VCAP and hence applications using lower values of capacitor would need a capacitor change when migrating to the newer technology part.
This application note highlights the differences between the CY14B256L/STK14D88 and the CY14B256LA and the parameters of significance that must be considered while migrating.
