Product details
Overview
S25FL128LDPMFV003 from Infineon is a 128-Mbit serial NOR flash memory with 3.0 V supply voltage, 133 MHz Quad SPI interface, uniform 256-byte programmable sectors, and hardware write protection. It serves as non-volatile program/data storage in microcontroller-based boot code and firmware update systems.
For engineers reviewing the S25FL128LDPMFV003 datasheet, S25FL128LDPMFV003 pinout, S25FL128LDPMFV003 application, or S25FL128LDPMFV003 equivalent, key selection criteria include sector architecture compatibility, Quad SPI timing compliance, write-protect granularity, and industrial temperature operation (–40°C to +105°C).
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended Quad I/O mode supporting single/dual/quad read commands. It uses a 4-byte address space with configurable dummy cycles and supports volatile/non-volatile status register writes.
Internal architecture includes a 128 Mbit (16 MB) array organized as 32,768 sectors of 256 bytes each, with erase suspend/resume capability and 100K program/erase cycle endurance. The device complies with JEDEC JESD216B for SFDP parameter table support.

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 |
|---|---|---|---|
| S25FL128SAGMFV000 | Same density and package but uses 1.8 V core voltage with dual-power supply (VCC/VCCQ); supports octal DTR mode up to 200 MHz | Targeted at low-power, high-throughput applications where host supports dual-voltage I/O and octal interface | Select when migrating to energy-efficient designs with bandwidth-demanding firmware streaming |
| MX25L12833FZNI-10G | 128 Mbit density, 3.3 V supply, 104 MHz Quad SPI, no SFDP support, different sector protection scheme | Lacks JEDEC-standardized configuration; requires custom driver integration and manual timing setup | Choose only if legacy design reuse mandates identical pinout and minimal BOM change without SFDP dependency |
Compared with S25FL128SAGMFV000, the S25FL128LDPMFV003 offers simpler 3.3 V-only power architecture and guaranteed SFDP compliance; versus MX25L12833FZNI-10G, it delivers standardized initialization and finer 256-byte sector granularity for secure OTA updates.

FAQ
Is S25FL128LDPMFV003 compatible with standard SPI controllers?
Yes, it supports standard SPI modes (0,3) for basic read/write/erase operations. Full Quad SPI functionality requires host controller support for extended command sets (0x6B, 0xEB, 0x38) and proper dummy cycle configuration per JEDEC JESD216B.
What is the minimum erase block size supported?
The device supports uniform 256-byte sector erase as the smallest erasable unit. There is no smaller sub-sector or page-erase capability; all erase operations target complete 256-byte sectors.
Does this part support execute-in-place (XIP) operation?
No, S25FL128LDPMFV003 does not support true XIP. While Quad SPI enables fast linear reads, code execution requires copying to RAM. The device lacks internal prefetch buffers or cache controllers needed for direct execution.
How is hardware write protection configured?
Hardware write protection is enabled by pulling the WP# pin low. This locks all sectors unless the status register's Block Protect bits are cleared via software command - a two-step process requiring both WP# deassertion and register write.
