Product details
Overview
S25FL128LAGMFI013 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3V supply voltage, 100 MHz clock frequency, and 1.2V I/O voltage compatibility. It supports XIP (execute-in-place), sector erase, and deep power-down mode for low-power embedded applications including industrial HMIs and automotive infotainment boot storage.
For engineers reviewing the S25FL128LAGMFI013 datasheet, S25FL128LAGMFI013 pinout, S25FL128LAGMFI013 application, or S25FL128LAGMFI013 equivalent, key selection criteria include quad SPI timing compliance, 1.8V/3.0V I/O flexibility, sector protection granularity, and AEC-Q100 Grade 3 qualification for extended temperature operation.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with enhanced quad I/O (QPI) mode enabling 4-bit data transfers per clock cycle. It uses uniform 4-KB sectors and 64-KB blocks for erase operations, with hardware write protection via WP# pin and software-controlled status register locking.
The memory array is organized as 16,384 pages of 256 bytes each, supporting byte-level read and program operations. Internal ECC corrects single-bit errors during read, and the device includes a 64-byte one-time programmable (OTP) area for secure configuration storage.
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 |
|---|---|---|---|
| MX25L12833FZNI-10G | 128 Mbit, 3V, 104 MHz max clock; no AEC-Q100 qualification; 1.8V I/O only | Targeted at commercial-grade consumer electronics, not automotive or extended-temp industrial use | Select if cost-sensitive and operating within 0°C–70°C ambient with no automotive compliance requirement |
| S25FL128SAGMFI001 | Same density and package; supports octal DTR mode (up to 400 MHz); AEC-Q100 Grade 2 (−40°C to +125°C) | Used where higher bandwidth or wider temperature margin is needed, e.g., ADAS domain controllers | Choose when future-proofing for higher-speed interfaces or requiring Grade 2 thermal range |
Compared with MX25L12833FZNI-10G, S25FL128LAGMFI013 provides automotive qualification and dual-voltage I/O; versus S25FL128SAGMFI001, it trades octal DTR bandwidth for lower cost and simpler controller support while retaining Grade 3 operation.

FAQ
Is S25FL128LAGMFI013 pin-compatible with earlier S25FL128L variants?
Yes, it maintains identical 8-pin SOIC package and pinout with S25FL128LxxxFI0xx parts. The 'A' suffix denotes updated process and enhanced ECC implementation, but electrical and mechanical compatibility is preserved for drop-in replacement in existing designs.
Does this device support XIP (execute-in-place) mode?
Yes, S25FL128LAGMFI013 supports XIP operation in both standard SPI and QPI modes. The memory array is directly accessible by the host MCU's bus interface when configured with appropriate prefetch and cache settings, eliminating need for RAM loading.
What is the purpose of the 64-byte OTP area?
The 64-byte one-time programmable area stores immutable data such as unique device identifiers, cryptographic keys, or calibration constants. Once programmed, bits can only be changed from '1' to '0', ensuring tamper resistance for security-critical parameters.
How does deep power-down mode affect wake-up time?
In deep power-down mode, wake-up latency is 35 µs maximum after CS# deassertion. This enables rapid resumption of firmware reads during periodic sensor polling or communication bursts without sacrificing ultra-low standby current.
