Product details
Overview
S25FL256LAGMFA003 from Infineon is a 256-Mbit serial NOR flash memory with Quad SPI interface, 3.0 V supply voltage, 133 MHz clock frequency, and 8-pin SOIC package. It supports XIP (execute-in-place), sector erase, and deep power-down mode for low-power embedded applications including industrial controllers and IoT edge nodes.
For engineers reviewing the S25FL256LAGMFA003 datasheet, S25FL256LAGMFA003 pinout, S25FL256LAGMFA003 application, or S25FL256LAGMFA003 equivalent, key selection criteria include read latency, write endurance (100K cycles), data retention (20 years), and Quad SPI command set compliance per JEDEC JESD216B.
Technical Context
This device implements a standard SPI-compatible command set extended with Quad I/O support for 4-bit data transfers per clock cycle. It uses a 64-byte page programming buffer and features configurable 4-KB uniform sectors with individual lock bits for firmware protection.
Internal architecture includes a 256-Mbit (32 MB) array organized as 512 pages of 64 KB each, with dual-bank operation enabling concurrent read-while-write capability. The device supports both volatile and non-volatile status register configuration for boot mode and security settings.

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 |
|---|---|---|---|
| S25FL256SAGMFA000 | Same density and package but supports 166 MHz clock and enhanced security (AES-256 encryption) | Required where cryptographic firmware integrity verification is mandated (e.g., medical Class II devices) | Select when AES-based secure boot is needed; otherwise S25FL256LAGMFA003 offers cost-optimized performance |
| MX25L25645GMI-13G | 256 Mbit, 133 MHz, but uses different SFDP layout and lacks deep power-down mode (5 µA vs. 1 µA) | Suitable for cost-sensitive consumer applications where ultra-low standby current is not critical | Choose for legacy design continuity if migrating from Macronix platform; verify SFDP parser compatibility |
Compared with S25FL256SAGMFA000, the S25FL256LAGMFA003 trades hardware encryption for lower unit cost and identical core timing, while versus MX25L25645GMI-13G it delivers superior power efficiency and JEDEC-standardized configuration-critical for scalable industrial firmware deployment.

FAQ
Is S25FL256LAGMFA003 compatible with standard SPI controllers?
Yes, it operates in standard SPI mode (single I/O) by default and supports all JEDEC-standard SPI commands. Quad SPI mode requires explicit enable via status register bit QE=1 and compatible host controller timing setup.
What is the maximum clock frequency supported in Quad SPI mode?
The device supports up to 133 MHz in Quad SPI mode, delivering 532 MB/s effective throughput. This is specified under VCC = 3.0–3.6 V and ambient temperature range –40°C to +85°C per datasheet Rev. 1.7.
Does this part support execute-in-place (XIP) operation?
Yes, S25FL256LAGMFA003 supports true XIP operation with zero wait-state access at 133 MHz in Quad SPI mode. Internal address latching and pipeline prefetch enable continuous instruction fetch without CPU stalls.
How is sector protection implemented on this device?
Sector protection is implemented via software-controlled status register bits (SRWD, BP0–BP3) and hardware WP# pin. Each 4-KB sector can be individually locked using block protect bits, preventing program/erase operations until unlocked via specific command sequence.
