Product details
Overview
S25FL256LDPMFV003 from Infineon is a 256-Mbit (32-MB) serial NOR flash memory with Quad SPI interface, 133 MHz clock frequency, and 1.8 V core voltage. It supports XIP (execute-in-place), dual/quad I/O protocols, and offers 100K program/erase cycles with 20-year data retention - deployed in industrial PLC firmware storage and automotive ADAS boot code storage.
For engineers reviewing the S25FL256LDPMFV003 datasheet, S25FL256LDPMFV003 pinout, S25FL256LDPMFV003 application, or S25FL256LDPMFV003 equivalent, key selection criteria include quad-SPI timing compliance, 1.8 V VCC tolerance, sector protection granularity, erase suspend/resume capability, and JEDEC JESD216 Rev C SFDP support for auto-configuration.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended quad I/O mode compliant with JEDEC JESD216C. It uses a 64-byte page programming buffer and supports uniform 4-KB sectors and 64-KB blocks for flexible firmware partitioning.
Internal architecture includes a 32-bit address space, hardware write protection via WP# pin and status register bits, and configurable reset behavior (hardware reset via RESET# or software reset command). Erase operations are fully managed by on-die logic without host intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 MB) - sufficient for full bootloader + secure firmware image + parameter storage in Tier-1 automotive ECUs |
| Interface | Quad SPI (x4 I/O) - enables 532 MB/s effective throughput at 133 MHz, reducing boot time vs. standard SPI |
| Supply Voltage | 1.71–1.95 V - matches low-voltage SoC I/O domains and reduces power in always-on subsystems |
| Erase Endurance | 100,000 cycles per sector - supports over-the-air (OTA) update logging and dynamic configuration storage |
| Data Retention | 20 years at 85°C - validated for under-hood automotive applications per AEC-Q100 Grade 2 |
| Operating Temp | −40°C to +105°C - qualified for extended temperature range industrial control and ADAS modules |
Pinout & Package
Package: 8-pin SOIC (208-mil width), RoHS-compliant, Pb-free, moisture sensitivity level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO / IO1 | Serial Output / Quad I/O Line 1 | Bi-directional data line used for output during read and input during quad write/program |
| SI / IO0 | Serial Input / Quad I/O Line 0 | Primary input for commands, addresses, and data; also functions as bidirectional I/O in quad mode |
| WP# | Write Protect Input | Hardware-enabled sector protection; active-low signal locks status register and selected sectors |
| HOLD# | Hold Input | Pauses ongoing serial transfer without deselecting device; maintains internal state during host interrupt |
| RESET# | Hardware Reset Input | Asynchronous active-low reset that returns device to power-on state, clearing volatile status bits |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with wrap-around burst | Enables continuous 4-byte address wrap for efficient sequential code fetch in XIP mode |
| Erase suspend/resume | Allows host to pause block erase to service high-priority read requests, critical for real-time firmware updates |
| JESD216C SFDP support | Provides standardized, self-describing parameter table for automatic driver initialization without hard-coded timing values |
| Secure OTP area (512 B) | Dedicated one-time-programmable region for storing cryptographic keys or calibration data with lock-bit protection |

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 S25FL256SAGMFV000 | Same die, legacy marking; identical electrical specs but lacks updated SFDP revision C descriptor table | No impact on basic boot functionality; may require driver patch for advanced auto-configuration features | Select only if legacy design reuse mandates exact historical part number traceability |
| Winbond W25Q256JWSIQ | 3.3 V supply, different sector map (4-KB + 32-KB), no built-in OTP, lower temp grade (−40°C to +85°C) | Not suitable for under-hood automotive or extended-temp industrial use; requires voltage translation in 1.8 V systems | Consider only for cost-sensitive consumer or non-automotive embedded designs with relaxed thermal and security requirements |
Compared with S25FL256SAGMFV000, this part adds JESD216C SFDP support for robust driver portability; versus W25Q256JWSIQ, it delivers automotive-grade reliability, 1.8 V operation, and secure OTP - critical for safety-certified firmware storage.

FAQ
Is S25FL256LDPMFV003 AEC-Q100 qualified?
Yes, it is qualified to AEC-Q100 Grade 2 (−40°C to +105°C) with full test reports available upon request. Qualification covers HTOL, ESD, latch-up, and temperature cycling per automotive stress test standards.
Does this device support execute-in-place (XIP) mode?
Yes, it supports true XIP operation with zero-wait-state access at up to 133 MHz in quad I/O mode. The internal address decoder and prefetch buffer enable deterministic instruction fetch without external caching.
What is the purpose of the 512-byte OTP area?
The OTP area is factory-laser-fused and permanently locked after programming. It stores immutable data such as asymmetric key pairs, device-specific calibration constants, or secure boot root-of-trust seeds - inaccessible to firmware post-lock.
Can HOLD# and RESET# pins be left unconnected in PCB layout?
No. HOLD# must be pulled high via 10 kΩ resistor to VCC; RESET# must be actively driven or pulled high. Floating these pins risks spurious hold states or unintended resets during power ramp, violating JEDEC SPI-3 compliance.
