Product details
Overview
S25FL256LAGMFI000 from Infineon is a 256-Mbit serial NOR flash memory with quad SPI interface, 3.0–3.6 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 S25FL256LAGMFI000 datasheet, S25FL256LAGMFI000 pinout, S25FL256LAGMFI000 application, or S25FL256LAGMFI000 equivalent, key selection criteria include quad I/O timing compliance, sector protection granularity, write endurance (100K cycles), and retention (20 years) at 85°C.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode for high-speed data transfer. It uses a 64-byte page programming buffer and supports uniform 4-KB sectors with individual lock/unlock capability.
The memory array is organized as 512 K × 64 bits, with dual-bank architecture enabling concurrent read-while-write operation. Erase suspend/resume and volatile status register write protection are supported.

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 |
|---|---|---|---|
| S25FL256SAGMFI010 | Same density and package, but includes built-in ECC and enhanced security registers | Required for medical/automotive functional safety compliance (ISO 26262 ASIL-B) | Select when end-equipment certification mandates error correction or secure boot features |
| MX25L25645GMI-10G | 256 Mbit, 104 MHz max clock, no VIO pin (single 3.3 V supply), 100K endurance | Lacks separate I/O voltage rail and RWW capability; simpler BOM for cost-sensitive consumer designs | Choose for price-sensitive applications where dual-rail flexibility and concurrent operation are not required |
Compared with S25FL256SAGMFI010, this part trades ECC and security registers for lower cost and identical timing performance; versus MX25L25645GMI-10G, it adds VIO separation and RWW at higher unit cost but enables more robust industrial firmware architectures.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL256LAGMFI000 supports up to 133 MHz in Quad SPI (QPI) mode, delivering 532 MB/s effective throughput. This timing is specified under VCC = 3.0–3.6 V and ambient temperature range –40°C to +85°C, with setup/hold margins verified per JEDEC JESD252A.
Does this device support execute-in-place (XIP) operation?
Yes, the device supports true XIP operation with zero-wait-state random access from any address. Internal address latching and prefetch buffers enable deterministic instruction fetch timing, eliminating the need for external RAM caching in boot loader implementations.
How many sectors does the memory array contain, and what is their size?
The 256-Mbit array contains 512 uniform sectors, each 4 KB in size. All sectors support independent program/erase operations and individual lock/unlock control via status register bits or hardware WP# pin assertion.
Is there a separate I/O voltage supply pin, and what is its valid range?
Yes, Pin 1 (VIO) provides a dedicated I/O supply rail with a valid range of 1.65 V to 3.6 V. This allows interfacing with mixed-voltage systems-for example, 1.8 V host controllers driving a 3.3 V core-without level-shifting components.
