Product details
Overview
S25FS128SAGMFI100 from Infineon is a 128 Mb (16 MB) serial NOR flash memory IC with SPI Multi-I/O interface, operating at 1.8 V supply, supporting DDR Quad I/O read up to 80 MBps, hybrid and uniform sector erase options, and integrated hardware ECC for single-bit error correction. It targets boot code storage in industrial microcontroller systems requiring AEC-Q100 Grade 2 qualification (–40°C to +105°C).
For engineers reviewing the S25FS128SAGMFI100 datasheet, S25FS128SAGMFI100 pinout, S25FS128SAGMFI100 application, or S25FS128SAGMFI100 equivalent, key selection criteria include its 1.8 V operation, 80 MBps DDR Quad I/O throughput, OTP array size, sector protection granularity, and WSON 6 × 8 mm package compatibility with legacy S25FL-S footprints.
Technical Context
This device implements Infineon's Eclipse architecture with 65-nm MIRRORBIT™ technology, enabling high-density, low-voltage NOR flash operation. It supports both SDR and DDR SPI modes, with configurable 24-/32-bit addressing and SFDP/CFI for runtime configuration discovery.
The command set includes suspend/resume for program and erase operations, hybrid sector layout (eight 4-KB + one 32-KB sectors), and advanced sector protection (ASP) with password-controlled read access - all managed via status and configuration registers accessible over SPI.

| 4 (VSS) | Ground | Signal and power return path; connects to PCB ground plane beneath exposed pad for thermal stability |
| 5 (VCC) | Power Supply | 1.8 V core and I/O supply; requires local 1 µF ceramic decoupling adjacent to pin |
| 6 (SI / IO0) | Serial Input / I/O0 | Command/data input in SDR; bidirectional I/O0 in multi-I/O; supports address/command latching on rising SCK edge |
| 7 (SCK) | Serial Clock | Input clock driving all SPI transactions; supports modes 0 and 3; max 133 MHz for SDR, 80 MHz for DDR |
| 8 (IO3 / RESET#) | I/O3 / Reset | Multi-function pin: I/O3 in Quad mode; active-low hardware reset that clears internal state and exits DPD mode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Cypress S25FL128SAGMFI100 | Same pinout, identical command set, but lacks DDR mode support and has lower max read rate (66 MBps Quad I/O only) | Not suitable for XIP-critical designs requiring DDR bandwidth; acceptable where cost sensitivity outweighs performance | Select only if DDR capability is unnecessary and legacy S25FL-S footprint reuse is mandatory |
| Winbond W25Q128JVSIM | 1.8 V operation, same density, but uses standard SPI (no DDR) and lacks ASP; OTP size is 512 bytes | Lower security assurance for boot code; limited sector protection granularity increases risk of accidental firmware corruption | Prefer for cost-driven consumer IoT where AEC-Q100 or 20-year retention is not required |
Compared with S25FL128SAGMFI100 and W25Q128JVSIM, the S25FS128SAGMFI100 delivers unique DDR bandwidth, ASP with password control, and 1024-byte OTP - making it the only choice for AEC-Q100 Grade 2 automotive boot memory requiring both speed and secure partitioning.

FAQ
What is the maximum clock frequency supported in DDR mode?
The S25FS128SAGMFI100 supports DDR Quad I/O operation up to 80 MHz clock frequency, delivering 80 MBps effective read bandwidth. This is specified in the AC characteristics section (Rev. *O, Table 6-5) and validated across the full –40°C to +105°C temperature range with 1.8 V supply.
Does this part support 32-bit addressing for devices >16 MB?
Yes - the S25FS128SAGMFI100 supports both 24-bit and 32-bit addressing modes via the Extended Address Register (EAR), enabling seamless migration paths to higher-density FS-S family members while retaining identical command structure and footprint.
How is the OTP array accessed and protected?
The 1024-byte OTP array is accessed via dedicated JEDEC-standard One-Time Program commands (0x4B, 0x42). Once programmed, bits cannot be reset; protection is enforced by hardware - no software or register-based override exists, ensuring cryptographic key immutability after initial programming.
Can the device enter deep power-down mode during active SPI communication?
No - deep power-down (DPD) mode is entered only via explicit 0xB9 command and requires CS# to remain asserted for ≥100 ns after command completion. Any SPI activity during DPD entry aborts the transition; recovery requires CS# deassertion followed by 100 µs delay before issuing release command (0xAB).
