IFXS25FL128SAGNFI011
Overview
The S25FL128SAGNFI011 is a high-performance 128Mbit (16MB) NOR Flash memory IC featuring a Quad I/O SPI interface capable of clock speeds up to 133 MHz. It utilizes 65nm MirrorBit technology to provide high-density non-volatile storage with integrated Error Correction Code (ECC) for enhanced data reliability. This part supports both Single Data Rate (SDR) and Double Data Rate (DDR) read operations to maximize throughput in high-speed embedded systems.
Why Choose This Part
This memory IC features internal hardware ECC that automatically detects and corrects single-bit errors, significantly increasing data integrity over its 20-year retention life. It offers versatile power profiles with a standby current of 70 uA and supports Quad DDR modes for high-bandwidth data transfer using fewer pins than parallel flash.
Applications
Key Specifications
Getting Started
To interface with this device, ensure your SPI controller supports Mode 0 or Mode 3 and can handle the 2.7V to 3.6V supply range. Engineers should implement the standard JESD216B Serial Flash Discoverable Parameters (SFDP) protocol to automatically identify memory characteristics during initialization. For development, use a logic analyzer to verify the Quad I/O handshake and refer to the Infineon low-level driver (LLD) for sample C code implementation.
