Product details
Overview
S25FL256LDPNFN013 from Cypress Semiconductor is a 256 Mbit (32 Mbyte) serial NOR flash memory with SPI Multi-I/O interface, supporting SDR/DDR Quad I/O and QPI modes up to 133 MHz clock rate, 66 MB/s read throughput, 4 KB uniform sector erase, and 100,000 program-erase cycles. It operates from 2.7 V to 3.6 V across –40°C to +105°C and is used in boot code storage for industrial microcontrollers.
For engineers reviewing the S25FL256LDPNFN013 datasheet, S25FL256LDPNFN013 pinout, S25FL256LDPNFN013 application, or S25FL256LDPNFN013 equivalent, key selection criteria include quad-mode timing compliance, SFDP register support, security region configuration, and industrial temperature-grade endurance validation.
Technical Context
The S25FL256LDPNFN013 implements a 65 nm floating gate architecture with a 256-byte page programming buffer and supports burst wrap, continuous XIP, and QPI read modes. Its Serial Flash Discoverable Parameters (SFDP) table enables automatic host configuration of read commands and timing parameters.
Erase operations are fully uniform-4 KB sectors, 32 KB half-blocks, 64 KB blocks-and both program and erase suspend/resume functions are implemented in hardware. Security includes four 256-byte non-volatile security regions, individual sector lock, and power supply lock-down protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
Package: 16-pin SOIC 300 mil (SO3016), Pb-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable for command latching; must be held low for entire command sequence including address and data phases. |
| SCK | Serial Clock Input | Edge-triggered clock for all SPI modes; supports up to 133 MHz SDR or 66 MHz DDR; phase/polarity modes 0 and 3 supported. |
| SI / IO0 | Serial Input / I/O0 | Single-bit data input in standard SPI; becomes bidirectional I/O0 in Dual/Quad modes; internal pull-up enabled by default. |
| SO / IO1 | Serial Output / I/O1 | Single-bit data output in standard SPI; becomes bidirectional I/O1 in Dual/Quad modes; supports high-speed Quad I/O read bursts. |
| WP# / IO2 | Write Protect / I/O2 | Hardware write protect when CR1V[1]=0; functions as IO2 in Quad mode; internal pull-up allows NC if unused. |
| IO3 / RESET# | I/O3 or Hardware Reset | Configurable: IO3 in Quad/QPI mode; RESET# when CR2V[7]=1 and CS# high; internal pull-up permits NC in most designs. |
| VDD | Power Supply | 2.7–3.6 V core and I/O supply; decoupling capacitor required within 10 mm of pin per layout guidelines. |

Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Enables 4-bit-wide command/address/data transfers with single-cycle instruction overhead - reduces command latency vs. standard SPI. |
| Serial Flash Discoverable Parameters (SFDP) | JEDEC JESD216B-compliant parameter table stored in dedicated address space; allows automatic host driver initialization without hard-coded timing values. |
| Program & Erase Suspend/Resume | Permits interrupting active program or erase to service higher-priority reads; resumes from exact byte offset - critical for real-time firmware updates. |
| Uniform 4 KB Sector Erase | Eliminates need for erase block management software; enables fine-grained firmware patching and secure over-the-air update partitioning. |
| Non-Volatile Security Regions | Four 256-byte regions outside main array store keys, certificates, or calibration data; protected independently via SRP bits and power-lockdown. |
Applications
| Industrial PLC Firmware Storage | Automotive ADAS Boot Memory |
|---|---|
Use Scenario: Storing bootloader and safety-critical firmware images in programmable logic controllers requiring field-upgradable code with tamper resistance. IC Role / Device Role / Timing Role: Primary non-volatile boot memory mapped to ARM Cortex-M7's XIP interface; delivers 66 MB/s Quad I/O reads to meet <500 µs boot latency target. Use Value: Uniform 4 KB erase enables atomic firmware patching; security regions store cryptographic keys isolated from main array to prevent extraction during physical attack. | Use Scenario: Holding boot code and sensor fusion algorithms for automotive camera ECU operating at 105°C ambient under hood. IC Role / Device Role / Timing Role: NOR flash directly interfaced to TI TDA4VM SoC via QPI; supports simultaneous read while programming for dual-bank OTA updates. Use Value: Industrial Plus temperature rating (–40°C to +105°C) and 100K cycle endurance ensure 15-year vehicle lifecycle compliance without refresh. |
| Medical Imaging System Configuration | Smart Grid RTU Data Logging |
Use Scenario: Storing calibration tables, DICOM metadata templates, and FPGA configuration bitstreams in portable ultrasound devices. IC Role / Device Role / Timing Role: Secondary SPI flash paired with main MCU; accessed via DDR Quad I/O at 66 MHz to sustain >40 MB/s streaming read for real-time image reconstruction buffers. Use Value: SFDP register auto-detection eliminates manual timing tuning across production batches; 20-year data retention guarantees calibration integrity over device lifetime. | Use Scenario: Recording time-stamped grid event logs and firmware revision history in outdoor-mounted remote terminal units exposed to wide thermal cycling. IC Role / Device Role / Timing Role: Non-volatile logging memory with wear-leveling handled by host MCU; uses 4 KB sector erase to minimize write amplification on frequent timestamp updates. Use Value: Program suspend/resume allows log writes to yield to urgent SCADA polling interrupts; deep power-down current ≤2 µA extends battery backup runtime. |
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 |
|---|---|---|---|
| S25FL256SAGMFV000 | Same density and pinout; FL-S family; 90 nm process; max 104 MHz SCK; no DDR mode; 64 KB erase only. | Lacks DDR and SFDP; lower max clock limits read bandwidth to 52 MB/s; no program suspend/resume. | Select only if legacy FL-S footprint compatibility is mandatory and DDR/XIP performance not required. |
| MX25L25645GMI-10G | 256 Mbit, 3.3 V; supports QPI and 133 MHz, but no DDR; 100K cycles; no security regions; SFDP v1.5 only. | Missing security regions and pointer lock-down; no industrial-plus temp grade; limited SFDP parameter coverage. | Choose for cost-sensitive consumer applications where security and extended temperature are not mandated. |
Compared with S25FL256SAGMFV000 and MX25L25645GMI-10G, the S25FL256LDPNFN013 uniquely delivers DDR Quad I/O, full SFDP v1.6 support, program/erase suspend, and certified industrial-plus temperature operation - making it the only option meeting functional safety boot requirements in ISO 26262 ASIL-B systems.

FAQ
What package type does S25FL256LDPNFN013 use?
S25FL256LDPNFN013 uses a 16-pin SOIC 300 mil (SO3016) package with Pb-free finish and RoHS compliance. This package matches industry-standard footprints for drop-in replacement in existing PCB layouts designed for legacy SPI flash devices.
Does S25FL256LDPNFN013 support execute-in-place (XIP) operation?
Yes, S25FL256LDPNFN013 supports continuous XIP mode using Fast Read, Dual I/O, Quad I/O, or QPI commands. Its 66 MB/s Quad I/O read rate and burst wrap addressing enable deterministic instruction fetch latency suitable for Cortex-M and RISC-V cores.
How is security implemented in S25FL256LDPNFN013?
Security is implemented via four dedicated 256-byte non-volatile security regions outside the main array, individual sector lock bits, and power supply lock-down protection for Regions 2/3 and the pointer region. Protection is enforced by status register bits SRP0/SRP1 and requires password entry for unlock.
Can S25FL256LDPNFN013 replace older S25FL128L or S25FL064L devices?
Yes, S25FL256LDPNFN013 is footprint- and command-compatible with S25FL1-K and S25FL-P families. Pinout, voltage range, and basic SPI commands match, but users must validate DDR timing, SFDP parser behavior, and security register initialization in host firmware.
