Product details
Overview
S25FL128LAGMFA013 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 page programming. It serves as non-volatile program/data storage in microcontroller boot code applications.
For engineers reviewing the S25FL128LAGMFA013 datasheet, S25FL128LAGMFA013 pinout, S25FL128LAGMFA013 application, or S25FL128LAGMFA013 equivalent, key selection criteria include 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 support, enabling up to 400 MB/s effective throughput via four bidirectional data lines. It features a 64-KB uniform sector architecture with configurable 4-KB subsectors for flexible firmware update partitioning.
Internal address decoding supports sequential read across sectors without external address management. The memory includes hardware write protection via WP# pin and software-controlled block protection using status register bits SRWD, BP2–BP0.

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 |
|---|---|---|---|
| S25FL128SAGMFA000 | Same density and package, but supports octal DTR interface (up to 200 MHz DDR) and has different status register layout | Required for designs needing >400 MB/s read bandwidth or DDR timing compliance | Select only if octal DTR interface and higher bandwidth are mandatory; not drop-in compatible due to command set differences |
| MX25L12833FZNI-10G | 128 Mbit, 3.3 V, SOIC-8, but uses standard SPI (no QPI) and has slower 80 MHz max clock | Suitable for cost-sensitive applications where boot time is non-critical and QPI is unused | Choose when legacy SPI controller compatibility is required and bandwidth <320 MB/s is acceptable |
Compared with S25FL128SAGMFA000, this part trades octal DTR bandwidth for broader QPI compatibility and simpler command mapping; versus MX25L12833FZNI-10G, it delivers 25% higher read throughput and finer erase granularity at modest cost premium.

FAQ
What is the maximum clock frequency supported in Quad SPI mode?
The S25FL128LAGMFA013 supports up to 100 MHz in Quad SPI (QPI) mode, delivering up to 400 MB/s effective throughput. This frequency is specified under standard load conditions with proper PCB layout and termination, and remains stable across the full industrial temperature range (–40°C to +85°C).
Does this device support execute-in-place (XIP) operation?
Yes, the device supports XIP mode via continuous read commands, allowing microcontrollers to execute code directly from flash without loading into RAM. XIP requires stable clocking and proper cache coherency handling on the host side, and is validated for use with Infineon's XMC and AURIX microcontrollers.
How is hardware write protection implemented on this part?
Hardware write protection is controlled by the WP# pin: when held low, it locks all sectors configured as protected in the status register. Protection granularity is selectable per 64-KB sector or 4-KB subsector, and WP# must be externally pulled high to enable write/erase operations unless intentional lockdown is required.
What packaging and RoHS compliance status does this part have?
This part is supplied in an 8-pin SOIC-208 package with matte tin lead finish and is fully RoHS 2011/65/EU compliant. It meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) and is qualified for lead-free reflow soldering per IPC/JEDEC J-STD-020D.2.
