Product details
Overview
S25FL128LAGNFV013 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0–3.6 V supply voltage, 100 MHz clock frequency, and uniform 256-byte programming page size. It supports XIP (execute-in-place) operation in embedded microcontroller boot applications.
For engineers reviewing the S25FL128LAGNFV013 datasheet, S25FL128LAGNFV013 pinout, S25FL128LAGNFV013 application, or S25FL128LAGNFV013 equivalent, key selection criteria include read latency, sector erase granularity, write endurance (100k cycles), data retention (20 years), and industrial temperature range (–40°C to +85°C).
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with Quad I/O (QPI) mode for high-speed data transfer. It features a 64-MB address space mapped across 256 uniform sectors of 64 KB each, with configurable 4-KB subsectors for flexible firmware update management.
The memory uses stacked-gate NOR architecture with charge-trap technology, enabling single-bit error correction (ECC) support via external controller and hardware reset recovery. Write protection is implemented via status register bits and hardware WP# pin.
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 |
|---|---|---|---|
| CY15B104QN-PSOC | 4-Mbit FRAM with unlimited endurance and 15 ns read latency; no erase cycles required | Better suited for frequent parameter logging; lacks XIP support and sector-based firmware update capability | Select when write cycle count dominates over code storage density and XIP is not required |
| MX25L12833FZNI-10G | Same 128-Mbit capacity, but 1.8 V core voltage and 133 MHz max clock; different SOIC-8 pinout (pin 3 = RESET#) | Requires level-shifting for 3.3 V systems; supports faster clock but incompatible WP#/HOLD# pin mapping | Choose only if migrating from Macronix platform with existing PCB layout and 1.8 V I/O infrastructure |
Compared with CY15B104QN-PSOC and MX25L12833FZNI-10G, S25FL128LAGNFV013 offers optimal balance of XIP-ready 3.3 V operation, industrial temperature qualification, and proven firmware update architecture-making it preferred for MCU boot memory where code density, reliability, and ecosystem compatibility are critical.

FAQ
Is S25FL128LAGNFV013 compatible with standard SPI controllers?
Yes, it supports standard SPI modes (0,3) at up to 80 MHz and includes legacy single/dual I/O protocols. Quad SPI (QPI) mode requires explicit enable command but is backward-compatible with SPI host initialization sequences. No external level shifters are needed for 3.3 V SPI controllers.
Does this part support execute-in-place (XIP) operation?
Yes, S25FL128LAGNFV013 supports true XIP operation with ≤8 ns initial read latency in fast-read mode. The memory's uniform sector architecture and QPI interface allow direct instruction fetch by ARM Cortex-M and RISC-V MCUs without intermediate buffering.
What is the minimum erase block size for firmware updates?
The smallest erasable unit is a 4 KB subsector, enabled via status register configuration. Full 64 KB sector erase is default, but subsector erase allows targeted updates of configuration tables or patch regions without disturbing adjacent firmware sections.
How is data retention affected by operating temperature?
Data retention is specified at 20 years minimum at +85°C and extends beyond 30 years at +25°C. Accelerated life testing per JEDEC JESD22-A117 confirms retention compliance across the full –40°C to +85°C industrial range without derating.
