Product details

Overview

S25FL256LAGNFM013 from Infineon is a 256-Mbit serial NOR flash memory with quad SPI interface, 3.0 V supply voltage, 133 MHz read clock frequency, and uniform 4-KB sector erase capability. It serves as non-volatile program/data storage in microcontroller-based embedded systems requiring code XIP execution and firmware update support.

For engineers reviewing the S25FL256LAGNFM013 datasheet, S25FL256LAGNFM013 pinout, S25FL256LAGNFM013 application, or S25FL256LAGNFM013 equivalent, key selection criteria include quad I/O read bandwidth, sector protection granularity, write endurance (100K cycles), data retention (20 years), and industrial temperature range (-40°C to +85°C) compliance.

Technical Context

This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O mode supporting single/dual/quad read commands. It features a 64-byte page programming buffer and supports both volatile and non-volatile status register configuration for write protection and latency tuning.

Memory organization comprises 512 uniform 4-KB sectors and 32 64-KB blocks, enabling flexible firmware partitioning. The device uses CMOS floating-gate technology with on-chip charge pump for erase/program operations and includes hardware reset and deep power-down modes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial NOR flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S25FL256SAGNFM000	Same density and package but lacks secure silicon sector and program/erase suspend	Not suitable for OTA security-critical applications requiring key binding or real-time interrupt handling during flash ops	Select when cost sensitivity outweighs security and suspend functionality needs
MX25L25645GMI-13G	256 Mbit, 133 MHz quad SPI, but only 10K write cycles and 10-year retention at +85°C	Lower endurance and retention limit use in long-lifecycle industrial deployments	Prefer for consumer-grade products with shorter field life and lower update frequency

Compared with S25FL256SAGNFM000, this part adds secure silicon and suspend capability for robust OTA; versus MX25L25645GMI-13G, it delivers 10× higher endurance and double the data retention-critical for infrastructure-class deployments.

FAQ

What is the maximum clock frequency supported in quad SPI read mode?

The S25FL256LAGNFM013 supports up to 133 MHz in quad I/O read mode, delivering 532 MB/s effective throughput. This frequency is specified under industrial temperature conditions with proper signal integrity layout, including controlled impedance traces and matched trace lengths for all four IO lines.

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

Yes, the device supports true XIP operation with zero wait-state access at 133 MHz in quad mode. Internal address latching and pipeline prefetch enable deterministic instruction fetch timing, eliminating the need for external RAM caching in boot-critical paths.

How is sector protection configured-hardware or software?

Sector protection is configurable via both hardware (WP# pin assertion) and software (status register bits BP0–BP3). Hardware protection locks sectors during power-up; software protection allows dynamic locking/unlocking of any 4-KB sector through SPI commands without requiring WP# assertion.

Is the secure silicon sector reprogrammable?

No, the 256-byte secure silicon sector is one-time programmable (OTP). Once written, its contents cannot be erased or modified. It is intended for permanent storage of cryptographic keys, device IDs, or calibration constants that must remain immutable across the product lifecycle.
