Product details
Overview
S25FL128LDPMFV001 from Infineon is a 128-Mbit serial NOR flash memory with quad SPI interface, 3.0–3.6 V supply, 133 MHz read clock, and uniform 256-byte sector erase capability. It serves as non-volatile program/data storage in microcontroller boot loaders and FPGA configuration systems.
For engineers reviewing the S25FL128LDPMFV001 datasheet, S25FL128LDPMFV001 pinout, S25FL128LDPMFV001 application, or S25FL128LDPMFV001 equivalent, key selection factors include quad I/O read bandwidth, sector-erase granularity, write-protection flexibility, and industrial temperature range support.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O mode for high-speed data transfer. It supports both single and quad I/O read commands, with configurable dummy cycles and latency tuning for timing alignment.
Erase operations are supported at sector (256 B), block (4 KB, 32 KB, 64 KB), and chip level. Write protection is implemented via status register bits and hardware WP# pin, enabling flexible security partitioning across memory regions.

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 |
|---|---|---|---|
| S25FL128SAGMFV001 | Same density and voltage, but uses newer 65 nm process; 10% lower active current (18 mA vs. 20 mA) | Identical pinout and command set; optimized for battery-powered portable medical devices | Select when power efficiency outweighs cost sensitivity in portable designs |
| MX25L12833FZNI-10G | 133 MHz max read speed same, but only supports dual I/O (not quad); lacks program/erase suspend | Lower bandwidth limits suitability to non-real-time embedded controllers | Choose only if quad I/O and suspend features are not required and BOM cost is primary constraint |
Compared with S25FL128SAGMFV001, this part trades minor power savings for higher cost; versus MX25L12833FZNI-10G, it delivers essential quad I/O bandwidth and suspend functionality needed for deterministic boot and runtime update scenarios.
