S25FS512SAGNFI011

Product Overview

The Infineon Technologies S25FS512SAGNFI011, from the FS-S series, is a non-volatile NOR flash memory IC with 512 Mbit capacity and a 64M x 8 organization. It uses a serial SPI interface supporting Quad I/O and QPI operation at a clock frequency of 133 MHz. The device operates from a 1.7 V to 2 V supply and is specified for ambient temperatures from -40°C to 85°C. It uses an 8-WSON (6x8) surface-mount package with an exposed pad.

Key Features

• 512 Mbit non-volatile flash memory organized as 64M x 8.
• NOR flash technology with SPI Quad I/O and QPI interface.
• 133 MHz clock frequency.
• 1.7 V to 2 V supply voltage range.
• -40°C to 85°C (TA) operating temperature range.
• Surface-mount 8-WSON (6x8) package with 8-WDFN exposed pad.

Applications

• Embedded systems that retain firmware, boot code, or configuration data when power is removed.
• Data-logging subsystems that store records through a serial SPI interface within a 1.7 V to 2 V supply range.
• Memory expansion for embedded host processors that access code or data through a serial flash interface.

Design & Procurement Notes

Designers should confirm that the host controller supports SPI Quad I/O and QPI signaling before selecting this device, since those interface modes determine how the data pins are used. The 133 MHz clock frequency calls for attention to trace length, loading, and signal integrity on the serial bus. The 1.7 V to 2 V supply range requires a regulated local supply and appropriate decoupling, and the -40°C to 85°C ambient rating should be checked against the expected operating environment. The 8-WSON (6x8) surface-mount package with an exposed pad requires a compatible land pattern, soldering process, and pad thermal connection.
