Product details
Overview
S25FL256LDPMFV001 from Infineon is a 256-Mbit serial NOR flash memory with quad SPI interface, 133 MHz clock frequency, 3.0–3.6 V supply voltage, and 100,000 program/erase cycles endurance. It operates in industrial temperature range (−40°C to +85°C) and is used in boot code storage for microcontroller-based edge IoT gateways.
For engineers reviewing the S25FL256LDPMFV001 datasheet, S25FL256LDPMFV001 pinout, S25FL256LDPMFV001 application, or S25FL256LDPMFV001 equivalent, key selection criteria include quad I/O timing compliance, sector protection granularity, reset recovery time, and WSON-8 package thermal performance in space-constrained embedded designs.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O (QPI) mode supporting single/dual/quad read commands. 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 bits.
It supports volatile and non-volatile configuration registers for latency tuning, dummy cycle control, and security lock bits. The internal state machine handles all erase and program sequencing without external timing constraints.
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 |
|---|---|---|---|
| Cypress S25FL256SAGMFV001 | Same die, legacy Cypress branding; identical electrical specs and timing parameters | No functional difference; supported by same Infineon software tools and programming adapters | Select when maintaining legacy BOM continuity or sourcing from pre-Infineon inventory channels |
| Winbond W25Q256JWEIQ | 256 Mbit, 1.8 V core, different command set (no QPI mode), 80 MHz max clock | Lacks quad I/O mode and industrial temp grade; requires voltage translation in 3.3 V systems | Only suitable if design already uses Winbond's SFDP-compatible toolchain and does not require QPI bandwidth |
Compared with S25FL256SAGMFV001, this part offers identical functionality under Infineon's unified support model; versus W25Q256JWEIQ, it delivers higher throughput, broader temperature operation, and hardware write protection architecture better suited for safety-critical boot storage.

FAQ
Is S25FL256LDPMFV001 pin-compatible with earlier S25FL256Lxxx variants?
Yes, it maintains identical WSON-8 pinout and electrical characteristics with prior S25FL256L revisions. No PCB redesign is required when migrating from S25FL256LDPMFV000 or S25FL256LDPMFV002, as confirmed by Infineon's migration advisory document AN512927.
Does this device support execute-in-place (XIP) operation?
Yes, S25FL256LDPMFV001 supports XIP mode via quad I/O read commands. Its 133 MHz clock and low-latency command pipeline allow direct instruction fetch by ARM Cortex-M and RISC-V cores without local RAM buffering.
What security features are implemented in hardware?
Hardware security includes OTP lock bits for permanent configuration locking, volatile/non-volatile status register protection, and WP#-enabled top/bottom 4-KB sector write protection. No cryptographic acceleration engine is integrated; security relies on access control and physical write disable.
Can this flash be programmed using standard SPI host controllers?
Yes, it operates in standard SPI mode (single I/O) for basic read/write/erase, but quad I/O mode requires MCU peripherals supporting QPI protocol extensions. Standard SPI controllers can initialize and verify, but full bandwidth requires QPI-capable hardware like STM32H7 or NXP i.MX RT1170.
