Infineon Technologies S25FL256LAGMFV000

Overview

S25FL256LAGMFV000 from Infineon is a 256-Mbit serial NOR flash memory IC with quad SPI interface, 3.0 V supply voltage, 133 MHz clock frequency, and uniform 4-KB sector erase capability. It serves as non-volatile program/data storage in microcontroller-based embedded systems requiring fast read access and reliable code execution.

For engineers reviewing the S25FL256LAGMFV000 datasheet, S25FL256LAGMFV000 pinout, S25FL256LAGMFV000 application, or S25FL256LAGMFV000 equivalent, key selection criteria include quad I/O read throughput, sector protection granularity, write endurance (100K cycles), data retention (20 years), and industrial temperature range support.

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O mode for high-speed data transfer. It supports continuous read, wrap-around burst, and configurable dummy cycle insertion to align with host timing requirements.

Internal architecture includes a 256-Mbit array organized as 512 pages of 64 KB each, with hardware-controlled sector protection and volatile/non-volatile status register configuration. Write operations are managed via command protocol with built-in write enable latch and busy flag polling.

FAQ

Is S25FL256LAGMFV000 qualified for automotive applications?

No. This variant is rated for industrial temperature range (–40°C to +85°C) and lacks AEC-Q100 qualification. For automotive use, Infineon recommends S25FL256SAGMFV001, which carries AEC-Q100 Grade 2 certification and additional security features required by automotive OEMs.

Does this device support execute-in-place (XIP) operation?

Yes. The device supports XIP mode via continuous read commands with wrap-around burst capability and configurable dummy cycles, enabling direct CPU instruction fetch from flash without RAM loading-reducing system memory footprint and boot latency.

What is the minimum erase block size supported?

The smallest erasable unit is a uniform 4-KB sector. There is no smaller erase granularity; 64-KB block erase is also supported but not required for partial firmware updates. Sector erase time is typically 0.5 seconds per sector.

Can HOLD# and WP# pins be used simultaneously in quad mode?

Yes. In quad SPI mode, HOLD# and WP# function as IO3 and IO2 respectively, and retain their dedicated hardware roles: HOLD# suspends active transfers, while WP# controls sector protection. Both operate independently without conflict during normal operation.
