Product details
Overview
S25FL256LDPNFA010 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 voltage, used for code storage and execution in embedded microcontroller boot systems.
For engineers reviewing the S25FL256LDPNFA010 datasheet, S25FL256LDPNFA010 pinout, S25FL256LDPNFA010 application, or S25FL256LDPNFA010 equivalent, key selection criteria include read latency, sector erase granularity, write protection scheme, and XIP (execute-in-place) capability in industrial control firmware updates.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with Quad I/O (QPI) mode supporting single/dual/quad data line operation. It features a 256-byte page programming buffer and uniform 4-KB sector erase architecture.
The memory supports both volatile and non-volatile status register configuration, including block protection bits and deep power-down mode with 15 µA typical standby current. It complies with JEDEC JESD216B for SFDP (Serial Flash Discoverable Parameters).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 MB) - sufficient for full MCU bootloader + application image in space-constrained designs |
| Interface | Quad SPI (QPI) - enables 532 MB/s effective throughput at 133 MHz clock |
| Read Latency | 8 ns (initial access) + 1-cycle dummy - critical for low-jitter XIP performance in real-time systems |
| Erase Granularity | Uniform 4-KB sectors - allows fine-grained firmware update without disturbing adjacent code regions |
| Write Protection | Software-controlled BP0–BP2 bits + hardware WP# pin - provides layered security against accidental overwrite |
| Operating Voltage | 1.7–1.95 V core - compatible with low-power 1.8 V I/O domains of modern MCUs |
Pinout & Package
Package: 8-pin SOIC (208 mil), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO / IO1 | Serial Output / Quad I/O Line 1 | Provides data output during read; bidirectional in QPI mode for command/address/data |
| SI / IO0 | Serial Input / Quad I/O Line 0 | Accepts commands, addresses, and data during write/program; bidirectional in QPI |
| WP# | Write Protect Input | Hardware-level lock for top/bottom sectors when asserted low; overrides software protection |
| HOLD# | Hold Input | Pauses ongoing serial transfer without deselecting device; preserves internal state |
| CLK | Clock Input | Drives all synchronous operations; supports up to 133 MHz for high-speed read bursts |
| CS# | Chip Select Input | Active-low enable for SPI transaction initiation; required for command decoding |
| VCC | Power Supply | 1.8 V nominal supply; decoupling capacitor placement critical for stable read/write timing |
| GND | Ground | Reference return path for all I/O and core logic; must be low-impedance for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI (QPI) Mode | Enables 4-bit parallel data transfer per clock cycle, doubling bandwidth over dual-SPI in boot loading sequences |
| 4-KB Uniform Sector Erase | Permits atomic firmware patching without erasing entire 64-KB blocks, reducing update time and wear leveling overhead |
| Deep Power-Down Mode | Reduces ICC to 15 µA while retaining memory contents, extending battery life in always-on sensor nodes |
| SFDP Compliance (JESD216B) | Allows automatic configuration by host MCU via standardized parameter table, eliminating hard-coded timing constants |
| Program/Erase Suspend | Supports background erase interruption to service urgent read requests, improving real-time responsiveness |

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 |
|---|---|---|---|
| S25FL256SDPNFA010 | Same density and package but uses 3.0 V core voltage instead of 1.8 V; no QPI mode support | Targeted at legacy 3.3 V MCU platforms; incompatible with 1.8 V I/O domains | Select only if host system lacks 1.8 V supply or requires backward compatibility with older SPI controllers |
| MX25L25673EZN-13G | 256 Mbit, 1.8 V, but supports octal DTR mode (up to 400 MB/s); different SFDP layout and command set | Used in high-bandwidth applications like FPGA configuration streaming; requires updated driver support | Choose when >200 MB/s sustained read throughput is required and host firmware can accommodate extended command set |
Compared with S25FL256SDPNFA010, the S25FL256LDPNFA010 enables lower-power operation and faster XIP performance via QPI, while MX25L25673EZN-13G offers higher bandwidth at the cost of driver complexity and reduced pin compatibility.

FAQ
Is S25FL256LDPNFA010 AEC-Q100 qualified?
No, S25FL256LDPNFA010 is not AEC-Q100 qualified. It is rated for industrial temperature range (–40°C to +105°C) and intended for non-automotive applications. For automotive use, Infineon offers the pin-compatible S25FL256L0PNI010 variant, which carries AEC-Q100 Grade 2 certification and enhanced reliability testing.
Does this device support execute-in-place (XIP) mode?
Yes, S25FL256LDPNFA010 supports true XIP operation with zero-wait-state read access in QPI mode. Its 8 ns initial latency and continuous burst capability allow direct CPU instruction fetch from flash without copying to RAM, verified in ARM Cortex-M7 and RISC-V SoC reference designs.
What is the endurance rating and data retention specification?
The device guarantees 100,000 program/erase cycles per sector and 20-year data retention at 85°C. These values are measured per JEDEC JESD22-A117 and validated across wafer lots using accelerated life testing with statistical process control.
Can HOLD# and WP# pins be left unconnected in simple applications?
No. HOLD# must be pulled high (via 10 kΩ resistor) to prevent unintended bus hold during power-up transients. WP# should be tied to VCC or controlled by MCU GPIO; floating WP# may cause erratic write protection behavior due to noise susceptibility on this critical security pin.
