Product details
Overview
S25FL128LDPMFI003 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0–3.6 V supply voltage, 133 MHz clock frequency, and uniform 4-KB sector erase capability. It operates in industrial temperature range (−40°C to +85°C) and supports XIP (execute-in-place) for embedded boot code storage in microcontroller-based systems.
For engineers reviewing the S25FL128LDPMFI003 datasheet, S25FL128LDPMFI003 pinout, S25FL128LDPMFI003 application, or S25FL128LDPMFI003 equivalent, key selection criteria include quad I/O timing compliance, sector protection granularity, write suspend/resume support, and industrial-grade reliability for firmware storage in edge nodes and programmable logic controllers.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with enhanced Quad SPI (QPI) mode enabling 4-bit data transfers per clock cycle. It features configurable write protection via software and hardware means, including top/bottom sector locking and volatile/non-volatile status register settings.
The memory array is organized as 256 K × 16 bits, supporting byte, word, and page programming with typical 8-ms page program time. Erase operations include chip-erase (typ. 40 s), sector-erase (typ. 0.5 s), and block-erase (typ. 1.5 s), all verified under JEDEC JESD22-A117 stress testing.

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 |
|---|---|---|---|
| S25FL128SAGMFI001 | Same density and package, but uses legacy SPI (no QPI mode); max clock 80 MHz | Lacks quad-mode bandwidth; unsuitable for XIP boot with tight latency budgets | Select when cost sensitivity outweighs performance needs and QPI is unused in target design |
| MX25L12833FZNI-10G | 128 Mbit, 104 MHz max clock, no program/erase suspend, no security register | No suspend capability limits real-time responsiveness; no hardware security for sensitive data | Choose only for non-critical consumer applications where certification and security are not required |
Compared with S25FL128SAGMFI001 and MX25L12833FZNI-10G, the S25FL128LDPMFI003 delivers higher bandwidth via QPI, real-time suspend/resume for deterministic interrupt latency, and hardware-enforced security-making it optimal for industrial and safety-aware firmware storage.

FAQ
Is S25FL128LDPMFI003 AEC-Q100 qualified?
No. This part is rated for industrial temperature (−40°C to +85°C) and is not AEC-Q100 qualified. For automotive applications requiring qualification, Infineon offers the S25FL128LDPNFI003 variant with AEC-Q100 Grade 3 certification and extended reliability testing.
Does this device support Dual Transfer Rate (DTR) mode?
No. The S25FL128LDPMFI003 supports standard SPI, Dual SPI, and Quad SPI (QPI) modes only. DTR functionality is not implemented; maximum data rate is achieved using QPI at 133 MHz with 4-bit transfers per clock cycle.
Can the security register be permanently locked?
Yes. The 512-byte security register can be permanently locked via the non-volatile security lock bit (SEC bit) in the configuration register. Once set, the register becomes read-only and cannot be unlocked or rewritten without device replacement.
What is the minimum VCC voltage for reliable operation?
The absolute minimum VCC is 2.7 V per datasheet Absolute Maximum Ratings, but functional operation is guaranteed only from 3.0 V to 3.6 V. Below 3.0 V, timing margins degrade and program/erase operations may fail or yield unpredictable results.
