AN100 - Replacing SRAM with FM1608B, FM16W08, FM1808B, or FM18W08

Introduction

Cypress offers a range of F-RAM devices in different densities that are pin-compatible with the industry standard SRAMs. Parallel F-RAM devices may be used as battery-backed SRAM replacements. This application note highlights the design considerations that you need to review before finalizing your design, when you choose FM1608B/FM16W08 (64-Kbit (8 K x 8) F-RAMs) and FM1808B/FM18W08 (256-Kbit (32 K x 8) F-RAMs).
