Overview

The S25FL064LABMFI011 is a 64Mbit (8MB) CMOS 3.0V Flash memory device utilizing 65-nm floating gate technology. It supports SPI, Quad I/O, and QPI interfaces with clock speeds up to 108 MHz to provide high-performance execute-in-place (XiP) capability for embedded systems.

Why Choose This Part

This device offers high-speed data transfer rates and flexible sector architecture with uniform 4KB sector erases for efficient memory management. It includes advanced security features such as individual block locking and password protection to prevent unauthorized modification of critical code.

Applications

Firmware Storage
Primary storage for bootloaders, operating systems, or application firmware in embedded systems requiring high reliability.
Execute-in-Place (XiP)
Utilizing high-speed Quad SPI (QPI) at 108 MHz to execute code directly from flash memory, reducing the need for large internal RAM.
Data Logging
Recording system events or sensor data into the 64Mbit non-volatile array with flexible 4KB, 32KB, and 64KB erase granularity.
Parameter Storage
Saving configuration settings and user preferences in the four 256-byte security regions located outside the main memory array.

Getting Started

Interface this memory to a microcontroller SPI or QSPI peripheral using standard 2.7V to 3.6V logic levels. Development can be accelerated using the Infineon (formerly Cypress) FL-L Flash memory driver library and evaluating performance on an STK-like development platform that supports 8-SOIC 209-mil footprints.
