Product details
Overview
S25FS128SAGNFM100 from Infineon is a 128 Mb (16 MB) serial NOR flash memory IC with SPI Multi-I/O interface, 1.8 V supply, 65-nm MIRRORBIT™ Eclipse architecture, and industrial temperature grade (–40°C to +85°C). It supports Quad I/O read at 66 MBps, 256-byte page programming, hybrid/ uniform sector erase options, and integrated hardware ECC for single-bit error correction.
For engineers reviewing the S25FS128SAGNFM100 datasheet, S25FS128SAGNFM100 pinout, S25FS128SAGNFM100 application, or S25FS128SAGNFM100 equivalent, key selection factors include DDR Quad I/O read performance (80 MBps), OTP array size (1024 bytes), AEC-Q100 Grade 3 qualification, 100,000 program-erase cycles, and BGA-24 FAB024 package compatibility.
Technical Context
This device implements a SPI-MIO (Multi-Input/Output) interface supporting standard SPI modes 0/3, Dual/Quad I/O, DDR Quad I/O, and QPI mode for XIP-capable burst wrap reads. It uses SFDP and CFI for standardized configuration discovery and integrates dedicated registers for block protection, advanced sector protection (ASP), and OTP control.
The embedded algorithm handles automatic ECC generation/correction, program/erase suspend-resume, and hybrid sector mapping-eight 4-KB + one 32-KB sectors at top/bottom address space, with remaining 64-KB sectors-or uniform 64-KB logical blocks for software compatibility.

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 |
|---|---|---|---|
| S25FS128SAGNFM010 | Same die, identical specs, but shipped in SOIC-16 package (300 mil) instead of BGA-24 | Requires different PCB layout and thermal management; not suitable for space-constrained designs | Select when board-level reworkability or socket-based prototyping is prioritized over miniaturization |
| MX25L12833FZC-10G | 128 Mb, 1.8 V, but lacks DDR mode, ASP, and OTP; max Quad I/O read = 40 MBps | Not qualified for automotive or medical use; no AEC-Q100 or IEC 62304 support | Consider only for cost-sensitive consumer applications where security and speed are secondary |
Compared with S25FS128SAGNFM010, this BGA variant offers superior board density and thermal performance; versus MX25L12833FZC-10G, it delivers higher bandwidth, certified reliability, and hardware-enforced security features essential for industrial and safety-critical systems.

FAQ
What is the maximum clock frequency supported in DDR Quad I/O mode?
The S25FS128SAGNFM100 supports up to 80 MHz clock frequency in DDR Quad I/O mode, delivering 80 MBps effective read throughput. This is specified under AC characteristics section 6.5 of the datasheet and requires proper impedance-controlled routing and termination matching on the host board.
Does this part support hardware reset via the IO3/RESET# pin?
Yes - the IO3 pin functions as an active-low hardware reset (RESET#) that asynchronously resets internal state machines and command logic. When asserted, it halts ongoing program/erase operations and returns the device to standby mode, independent of SPI clock or CS# state.
How is the OTP array protected after programming?
The 1024-byte OTP array can be permanently locked using the Program OTP Lock Bits command (0x98). Once locked, further writes to the OTP region are disabled at the hardware level, and read access remains enabled unless ASP password protection is separately applied to restrict readout.
Can this flash be used in a 3.3 V system?
No - the S25FS128SAGNFM100 is strictly a 1.8 V core device with absolute maximum VCC rating of 2.0 V. Operation above 2.0 V risks permanent damage. Level-shifting circuitry is required for interfacing with 3.3 V SPI controllers, and voltage translation must preserve timing margins for SCK and I/O signals.
