Version:

AN6022 describes the comparison of features, capabilities, and benefits between Cypress nvSRAM and BBSRAMs.

Introduction

With lead-free initiatives being implemented globally, nvSRAMs have become a popular choice for NV RAM selection. This application note explores the advantages of nvSRAM over battery backed SRAM (BBSRAM). It provides a comparison of features, capabilities, and benefits between Cypress’s nvSRAM and the BBSRAM technology from other manufacturers.
