IFXS25FL128SAGNFI001

Overview

The S25FL128SAGNFI001 is a 128 Mbit (16 MB) non-volatile CMOS NOR Flash memory device featuring MirrorBit technology and an Eclipse architecture. It supports high-speed Quad I/O SPI and Double Data Rate (DDR) interfaces, reaching clock frequencies up to 133 MHz for efficient data throughput. This 3V device is housed in a 16-lead SOIC package and includes advanced security features like a 1024-byte OTP array and Advanced Sector Protection (ASP).

Why Choose This Part

This device leverages MirrorBit technology to provide high density and reliable performance in a compact footprint. It supports 133 MHz clock speeds and DDR modes, enabling high-bandwidth data transfers that rival traditional parallel Flash while using fewer pins. The integration of a 1024-byte OTP array and ASP offers robust security and configuration options for sensitive system data.

Applications

Getting Started

To interface with this Flash memory, ensure your microcontroller SPI peripheral is configured for Mode 0 or Mode 3 and supports the 2.7V to 3.6V supply range. Engineers should refer to the Cypress/Infineon software driver libraries for standardized low-level command sets covering read, program, and erase operations. Verification can be performed using a standard logic analyzer or SPI debugger to monitor the Quad I/O communication.
