Summary
The application note discusses the differences between CY14B256LA in the latest 0.13u technology and STK14C88-3 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.
CY14B256LA is pin compatible and can replace the STK14C88-3 device with no changes or minimum changes to the
firmware. The value of VCAP in the existing design needs to be considered while replacing the part.
