IFXS25FS128SAGNFI101

Overview

The S25FS128SAGNFI101 is a 128Mbit non-volatile NOR Flash memory IC featuring high-speed Quad SPI and QPI interfaces. Operating from a low-voltage 1.7V to 2V supply, it achieves clock speeds up to 133 MHz for efficient data throughput. This device is housed in a space-saving 8-WSON package, making it suitable for compact embedded designs requiring reliable code storage and execution.

Why Choose This Part

This memory offers a high-performance 133 MHz clock rate, supporting Quad I/O and QPI modes for significantly faster read performance than standard SPI. The 1.8V supply range reduces power consumption in mobile and battery-operated systems, while the WSON-8 package provides a minimal footprint for dense PCB layouts. Low standby current of 25uA and a deep power-down mode of 6uA ensure long battery life in idle states.

Applications

Getting Started

To interface with this device, ensure your MCU or SoC supports 1.8V I/O levels or use appropriate level shifters, as it is not 3.3V tolerant. Implement standard SPI or Quad SPI drivers, taking care to configure the dummy cycles correctly for 133 MHz operation. For evaluation, use an Infineon Semper Flash development kit or a universal flash programmer that supports the 5x6mm WSON-8 footprint.
