Product details
Overview
S25FL256LDPNFV013 from Infineon Technologies is a 256-Mbit (32-MB) serial NOR flash memory with Quad SPI interface, 133 MHz clock frequency, and 1.8 V core supply voltage. It supports XIP (execute-in-place), dual/quad I/O protocols, and sector erase granularity down to 4 KB. Used in industrial PLC firmware storage and embedded boot code retention.
For engineers reviewing the S25FL256LDPNFV013 datasheet, S25FL256LDPNFV013 pinout, S25FL256LDPNFV013 application, or S25FL256LDPNFV013 equivalent, key selection criteria include read latency (8 ns address access time), program/erase endurance (100K cycles), data retention (20 years), and support for SFDP (Serial Flash Discoverable Parameters) for automatic configuration.
Technical Context
This device implements a standard SPI-compatible command set extended with Quad SPI opcodes (0x6B, 0xEB, 0xE7) and supports volatile/non-volatile status register writes. It uses a 65 nm process technology and includes hardware write protection via WP# pin and software-controlled block protection.
Internal architecture features a 256-byte page buffer for programming and a 4-KB uniform sector layout with 2048 sectors total. The device operates across industrial temperature range (–40°C to +85°C) and meets AEC-Q100 Grade 2 for automotive-qualified variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 MB) - sufficient for full bootloader + OS image + configuration tables in edge-node microcontrollers |
| Interface | Quad SPI (x4 I/O) - enables 532 MB/s peak throughput at 133 MHz, reducing firmware update time |
| Read Latency | 8 ns address access time - supports zero-wait-state XIP execution from flash on Cortex-M7/M33 cores |
| Erase Granularity | 4 KB uniform sectors - allows fine-grained firmware patching without erasing entire application image |
| Endurance | 100,000 program/erase cycles per sector - suitable for field-upgradable control logic with frequent parameter logging |
| Data Retention | 20 years at +85°C - ensures long-term reliability in unattended industrial gateways |
| Supply Voltage | 1.7–2.0 V core - compatible with low-power 1.8 V I/O domains and reduces system-level power conversion complexity |
Pinout & Package
Package: 8-pin SOIC (208 mil) with standard SPI pinout (CS#, IO0–IO3, WP#, HOLD#, CLK, VCC, VSS).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable for command/address/data transfer; supports multi-device daisy-chain or parallel configurations |
| CLK | Serial Clock | Master-generated timing reference up to 133 MHz; phase-agnostic for both CPOL=0/1 modes |
| IO0–IO3 | Quad Data I/O | Bidirectional pins supporting single/dual/quad I/O modes; IO0/IO1 used for standard SPI, all four for high-speed read/write |
| WP# | Write Protect | Hardware lock for status register and sector protection bits; prevents accidental firmware corruption during power transitions |
| HOLD# | Pause Transfer | Halts ongoing read/write without deselecting device; enables priority interrupt handling in real-time systems |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with 4-byte Address Mode | Enables direct addressing of full 256 Mbit space without bank switching, simplifying memory mapping in RTOS environments |
| SFDP Support (v1.6) | Allows host MCU to auto-detect timing parameters, erase sizes, and feature flags-eliminating hard-coded flash initialization sequences |
| Program/Erase Suspend | Permits background erase to be paused for urgent read operations, critical for deterministic response in motion-control applications |
| Security Register Lock | One-time programmable lock bit prevents modification of security-critical configuration fields like OTP area access permissions |
| AEC-Q100 Qualified | Validated for automotive ECU use cases including infotainment boot storage and ADAS sensor firmware caching |

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 |
|---|---|---|---|
| S25FL256SDSNFV010 | Same density and package but 104 MHz max clock; lacks SFDP v1.6 and program suspend | Lower throughput limits suitability for high-bandwidth boot scenarios | Select when cost sensitivity outweighs need for fastest read performance and advanced suspend features |
| MX25L25645GMI-13G | 256 Mbit, 133 MHz, but 3.3 V supply only; no AEC-Q100 qualification | Not suitable for automotive or mixed-voltage industrial designs | Choose only for legacy 3.3 V systems where voltage compatibility is guaranteed |
Compared with S25FL256SDSNFV010 and MX25L25645GMI-13G, the S25FL256LDPNFV013 uniquely combines 1.8 V operation, AEC-Q100 Grade 2, SFDP v1.6, and program/erase suspend-making it optimal for next-generation automotive and industrial edge devices requiring field-upgradability and long-term reliability.

FAQ
Does S25FL256LDPNFV013 support Dual SPI mode?
Yes, it supports Dual SPI (x2 I/O) using IO0 and IO1 pins with opcodes 0x3B and 0xBB. This mode delivers double the bandwidth of standard SPI and is enabled via status register bit SR[1], allowing backward compatibility with legacy controllers lacking Quad SPI support.
What is the minimum erase block size?
The minimum erase block size is 4 KB, implemented as uniform sectors. There are no smaller erase units such as 64 KB blocks or chip-erase-only options-the device exclusively uses 4 KB sectors across its full 32 MB array.
Is hardware reset required after power-on?
No hardware reset is required. The device initializes automatically upon VCC ramp and enters standby mode. Status register defaults are defined, and the first command must be WREN before any write/erase operation-no external RST# signal needed.
Can the security register be reprogrammed after locking?
No. Once the security register lock bit (SR[7]) is set to '1', it becomes permanently irreversible. This one-time programmable feature prevents post-deployment modification of security-critical fields including OTP area access permissions and protection settings.
