RENAT25SF641B-SHB-T
Overview
The AT25SF641B-SHB-T is a 64Mbit serial NOR Flash memory device designed for systems that require high-density non-volatile storage with high-speed performance. It supports Standard SPI, Dual I/O, and Quad I/O operations at clock frequencies up to 108 MHz, operating within a 2.7V to 3.6V supply range. The memory is organized as 8,192KB, making it suitable for firmware storage and code execution applications.
Why Choose This Part
This device offers high-speed Quad I/O performance which provides significantly higher throughput than standard serial flash. It features robust data protection mechanisms including memory protection bits and a hardware WP pin, plus OTP security registers for unique identification and sensitive parameters. The low 14uA standby current makes it an efficient choice for power-sensitive designs.
Applications
Key Specifications
Getting Started
Engineers can interface this device with any MCU supporting SPI, Dual SPI, or Quad SPI modes using standard serial flash drivers. Verify compatibility with the Serial Flash Discoverable Parameters (SFDP) register for simplified software integration. When designing the PCB, ensure short traces for the 108 MHz clock and place a 0.1uF decoupling capacitor close to the VDD pin of the 8-SOIC package.
