... Application Note Abstract This application note provides information for converting from CY14E256L/STK14C88 parts to the CY14E256LA. It lists the parameter differences between the parts and the design considerations when converting existing applications from CY14E256L/STK14C88 to CY14E256LA. Introduction Cypress CY14E256LA is a 5V, 32Kb x 8, 256 Kbit nvSRAM in 0 ...

... Parameters The CY14E256LA is a drop in replacement for CY14E256L/STK14C88 and will require minimum changes in the application board. However, the differences in parameters should be considered before replacing one part with the other. differences in parameters between CY14E256L/STK14C88 and CY14E256LA. Table 5. Parameter Comparison Parameter Description DC Parameters ...

... Software STORE, the first time the board is powerd up. October 5, 2009 STORE Cycles The NV STORE cycles endurance in CY14E256LA is lower than the endurance in the older 0.8u technology. However, this would not affect in most applications since all nvSRAMs – have infinite read/write endurance and the NV STORE ...

... Power up Recall Related Improvements Additional parameters are specified in CY14E256LA such as HSB Output Disable Voltage (V Time (t ), and HSB High Active Time (t LZHSB definition of the additional specs in power up. Also, note that HSB remains low until the end of the power up in the new part. ...

... CY14E256L/STK14C88 in the 0.8u technology. Several parameters related to HSB and power up have improved / specified in the new device enabling faster device response, greater data security and ease of design. CY14E256LA is pin compatible and can replace the CY14E256L/STK14C88 device with no changes or minimum changes to the firmware. The value the existing design needs to be considered while replacing the part ...
