AN72390 provides details for migrating from the CY14B101QX/CY14B512QX/CY14B256QX nvSRAM parts to CY14B101QXA/CY14B512QXA/CY14B256QXA parts in applications. This application note also lists the parameter differences between the parts and the design considerations for migration when converting applications to CY14B101QXA/CY14B512QXA/CY14B256QXA.

简介

Cypress CY14B101QXA is a 3 V, 1 Mbit (128 K x 8) serial (SPI) nvSRAM in 0.13 micron technology. This part is functionally equivalent to the CY14B101QX in the same technology with a few parameter enhancements and additional features. Due to these enhancements, there are a few differences in parameters. This application note highlights the differences between the CY14B101QX and the CY14B101QXA and lists the parameters of significance that must be considered while migrating. These differences and considerations are applicable to CY14B512QXA (3 V, 64 K x 8, 512 Kbit) and CY14B256QXA (3 V, 32 K x 8, 256 Kbit) serial (SPI) nvSRAMs, which are the replacement parts for CY14B512QX and CY14B256QX devices, respectively. This application note is described with respect to CY14B101QX and CY14B101QXA in the following sections. The same description applies to CY14B512QX/CY14B256QXand CY14B512QXA/ CY14B256QXA.
