Product details
Overview
S25FL256LAGNFI011 from Infineon is a 256-Mbit serial NOR flash memory with 3.0 V supply voltage, 133 MHz Quad SPI interface, uniform 256-byte programmable sectors, and hardware write protection. It serves as non-volatile code/data storage in microcontroller-based boot systems requiring fast read access and reliable firmware retention.
For engineers reviewing the S25FL256LAGNFI011 datasheet, S25FL256LAGNFI011 pinout, S25FL256LAGNFI011 application, or S25FL256LAGNFI011 equivalent, key selection criteria include Quad SPI timing compliance, sector protection granularity, erase suspend/resume capability, and industrial temperature range operation (–40°C to +85°C).
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended Quad I/O mode supporting single/dual/quad read commands per JEDEC JESD216B. It uses stacked-die architecture to achieve 256 Mbit density in a single package without internal interleaving.
Command execution follows SPI phase/polarity conventions (CPOL=0, CPHA=0), and supports volatile status register writes for temporary configuration changes. The memory array is organized into 512 uniform sectors of 256 KB each, enabling precise firmware update boundaries.
Key Specifications

| Interface | Quad SPI (x4 I/O) - delivers up to 532 MB/s effective throughput for sequential reads |
| Supply Voltage | 2.7 V to 3.6 V - compatible with 3.3 V logic domains and brown-out tolerant operation |
| Operating Temperature | –40°C to +85°C - qualified for industrial control and automotive body electronics |

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 |
|---|---|---|---|
| S25FL256SAGNFI010 | Same density and package, but supports octal DTR interface up to 200 MHz; lacks deep power-down mode | Better suited for high-throughput boot loading in performance-critical gateways | Select when bandwidth >532 MB/s is required and ultra-low standby current is not critical |
| MX25L25645GMI-10G | 256 Mbit, 3.3 V, but only supports dual I/O; 100,000-cycle endurance and –40°C to +105°C rating | Preferred for extended temperature automotive powertrain applications | Choose when wider temperature range is mandatory and quad interface is unnecessary |
Compared with S25FL256SAGNFI010 and MX25L25645GMI-10G, the S25FL256LAGNFI011 balances quad-speed performance, industrial temperature support, and ultra-low-power deep sleep-making it optimal for cost-sensitive, thermally constrained embedded systems requiring firmware update resilience.

FAQ
Is S25FL256LAGNFI011 compatible with standard SPI controllers?
Yes, it supports legacy SPI modes (single I/O) and is fully compliant with JEDEC JESD216B for Quad SPI operation. Standard SPI controllers can access basic functions, but Quad mode requires explicit enablement via Status Register bit 6 and appropriate command set support.
What is the minimum erase block size for firmware updates?
The device features uniform 256 KB sectors-the smallest erasable unit. There are no smaller sub-sector or page-erase capabilities; partial updates require copying modified data to a new sector before erasing the old one.
Does this part support execute-in-place (XIP) operation?
Yes, it supports XIP with low-latency continuous read mode (up to 133 MHz clock). Address wraparound and dummy cycle insertion are handled internally, enabling direct MCU instruction fetch without external buffering.
How is hardware write protection implemented on this device?
Hardware write protection is controlled by the WP# pin: when driven low, it locks all sectors except those enabled via the Status Register's Block Protect bits. Protection persists through power cycles and is independent of software commands.
