Product details
Overview
S25FL128LAGNFB011 from Infineon is a 128-Mbit serial NOR flash memory with Quad SPI interface, 3.0 V supply voltage, and 100 MHz clock frequency. It supports XIP (execute-in-place), dual/quad I/O modes, and offers 100K program/erase cycles with 20-year data retention. Used in industrial PLC firmware storage and embedded boot code applications.
For engineers reviewing the S25FL128LAGNFB011 datasheet, S25FL128LAGNFB011 pinout, S25FL128LAGNFB011 application, or S25FL128LAGNFB011 equivalent, key selection criteria include Quad SPI timing compliance, sector protection granularity, erase suspend/resume capability, and industrial temperature range (-40°C to +105°C) support.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O commands compliant with JEDEC JESD216B. It uses a 64-byte page programming model and supports uniform 4-KB sectors and 64-KB blocks for flexible firmware partitioning.
Internal architecture includes a 128-Mbit (16 MB) array organized as 32,768 pages of 512 bytes each, with hardware write protection via WP# pin and software-controlled sector lockdown. The device operates in single, dual, or quad I/O mode without requiring external level shifters.
Key Specifications

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 |
|---|---|---|---|
| S25FL128SAGNFB010 | Same density and package, but supports 133 MHz Quad SPI and enhanced security features (AES-256 encryption) | Required where encrypted firmware delivery or faster boot time is mandated | Select when AES-256 or >100 MHz throughput is needed; otherwise S25FL128LAGNFB011 remains cost-optimized |
| MX25L12833FZNI-10G | 128 Mbit, 3 V, SOIC-8, but only supports Dual SPI (not Quad) and lacks secure silicon sector | Suitable for legacy designs without XIP or cryptographic requirements | Choose only if existing PCB layout mandates identical pinout and no Quad SPI or security is required |
Compared with S25FL128SAGNFB010, this part trades off advanced security and speed for lower unit cost and proven qualification in long-lifecycle industrial programs; versus MX25L12833FZNI-10G, it delivers essential Quad SPI bandwidth and hardware-based sector protection missing in the Macronix variant.

FAQ
Is S25FL128LAGNFB011 compatible with standard SPI controllers?
Yes. It supports standard SPI command sets (Read Status, Read Data, Page Program, Sector Erase) and is backward-compatible with legacy SPI masters. Quad I/O mode requires explicit enable via Write Enable and Status Register write; single/dual modes operate without configuration.
Does this part support execute-in-place (XIP) functionality?
Yes. The device supports true XIP operation with continuous burst reads and wrap-around addressing. When mapped into processor memory space via a memory-mapped SPI controller, code executes directly from flash without copying to RAM.
What is the purpose of the Secure Silicon Sector?
The Secure Silicon Sector is a one-time programmable 256-byte region isolated from main memory. It is used to store cryptographic keys, device-specific identifiers, or calibration constants that must remain immutable after initial programming.
Can S25FL128LAGNFB011 be used in automotive applications?
Yes. While not AEC-Q100 qualified itself, it is widely deployed in automotive ADAS ECUs where ambient temperature does not exceed +105°C and system-level qualification covers the full module. Its industrial temperature rating and 20-year data retention meet functional safety requirements for non-safety-critical boot memory.
