Product details
Overview
S25FL128LAGMFA010 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 operates in industrial temperature range (−40°C to +85°C) and supports standard, dual, and quad I/O protocols for embedded boot code and firmware storage in microcontroller-based systems.
For engineers reviewing the S25FL128LAGMFA010 datasheet, S25FL128LAGMFA010 pinout, S25FL128LAGMFA010 application, or S25FL128LAGMFA010 equivalent, key selection criteria include read latency, sector erase granularity, write endurance (100K cycles), data retention (20 years), and support for SFDP (JEDEC JESD216) for automatic configuration.
Technical Context
This device implements a 4-wire SPI bus with optional dual/quad mode operation using single- or double-data-rate transfers. It features a 64-KB uniform sector architecture with 512 sectors, configurable 4-KB subsectors, and hardware write protection via WP# pin and status register bits.
The memory supports volatile and non-volatile status register writes, deep power-down mode (10 µA typical), and reset recovery without external reset signal. Command set complies with JEDEC JESD216B for SFDP v1.6A, enabling host auto-detection of flash capabilities.

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 400 MHz) and higher endurance (300K cycles) | Targeted at high-bandwidth applications like AI edge inference accelerators requiring faster code fetch | Select when >100 MHz SPI throughput or >100K endurance is required; not drop-in due to command set extension |
| MX25L12833FZC-10G | 128 Mbit, 3.3 V, SOIC-8, but lacks SFDP v1.6A and has fixed 64 KB erase only (no 4 KB subsectors) | Suitable for cost-sensitive consumer electronics where firmware update flexibility is secondary | Choose for legacy designs with static flash configuration; verify bootloader compatibility with missing SFDP support |
Compared with S25FL128SAGMFA000, this part trades bandwidth and endurance for broader command-set compatibility and lower cost; versus MX25L12833FZC-10G, it adds subsector erase and SFDP for future-proof firmware management in industrial systems.

FAQ
Is S25FL128LAGMFA010 pin-compatible with earlier S25FL128L versions?
Yes, it maintains identical 8-pin SOIC footprint and pin functions with S25FL128LxxxFxxx variants. The 'A' suffix denotes enhanced manufacturing process and updated qualification, but electrical and mechanical interfaces remain unchanged per Infineon's migration notice AN230017.
Does this device support XIP (execute-in-place) operation?
Yes, it supports true XIP via quad SPI with continuous read mode and wrap-around addressing. Latency is 8 ns for first word after address, enabling direct MCU code execution without RAM copy, provided the host controller supports QSPI memory-mapped mode.
What is the minimum pulse width for the WP# pin to activate hardware protection?
The WP# pin requires a stable low level for ≥20 ns before the next valid command to engage sector protection. This timing is specified in the AC Characteristics table of the official datasheet Rev. 1.4, Section 7.2, and applies to both volatile and non-volatile protection modes.
Can S25FL128LAGMFA010 be used with 1.8 V I/O systems?
No, it is strictly a 3.0–3.6 V device. Its I/O pins are not 1.8 V tolerant, and internal level-shifting circuitry is absent. Interfacing with 1.8 V controllers requires external voltage translation or selection of Infineon's S25FL064K series, which supports dual-voltage operation.
