Datasheet

Infineon S25FL256S Series Flash Memory, 256MB Memory Size, 133MHz Maximum Clock Frequency - S25FL256SAGNFI001

This flash memory provides non-volatile storage for embedded systems requiring high-density serial access. It operates as an SPI-based NOR device designed for surface-mounted applications within automotive and industrial settings, supporting large-capacity code and data retention across a wide operating temperature range.

Features and Benefits:

• 256MB capacity enables storage of extensive firmware images
• SPI interface supports synchronous transfers up to 133MHz
• 2.7V-3.6V supply range suits varied power architectures
• NOR cell organisation with 14.5ns random access reduces code fetch latency
• WSON 8mm 8-pin package facilitates compact surface mounting
• AEC‑Q100 qualification addresses automotive-grade reliability demands

Applications

• Suitable for ECU firmware and boot code storage in vehicles
• Ideal for industrial controllers requiring extended-temperature components
• Used with telematics units for large logging and update storage
• Can be used for secure boot and code execution in embedded systems
• Appropriate for mass storage in consumer devices with constrained board space

What word and bit organisation does it use for addressing?

The memory is organised as 256Mx1 bit with options including 128M, 256M and 64M words to accommodate different addressing schemes.

How many pins and what mounting approach are required on the PCB?

It uses an 8-pin WSON package intended for surface-mount soldering to the board.

What timing behaviour should designers expect for synchronous operation?

The device implements synchronous SPI timing, permitting clocked transfers at frequencies up to 133MHz for deterministic data throughput.

What environmental temperature range can it reliably operate within?

It is specified to function across an industrial range from -40°C to 85°C for harsh-environment deployment.
