This application note provides information for migrating from CY14E256L/STK14C88 parts to the CY14E256LA.
Cypress CY14E256LA is a 5 V, 256 Kbit (32 K x 8) nvSRAM in 0.13 u technology. It is a pin to pin functional equivalent of CY14E256L/STK14C88 (0.8 u) and is a drop in replacement in most AutoStore applications. However, in an existing AutoStore inhibit application, the circuit would require change in routing of power to the VCC pin and a firmware change to disable AutoStore.
This application note highlights the differences between the CY14E256L/STK14C88 and the CY14E256LA and the parameters of significance that must be considered while migrating.
