Product details
Overview
S25FL256LDPNFV011 from Infineon is a 256-Mbit serial NOR flash memory with Quad SPI interface, 3.0–3.6 V supply voltage, 133 MHz clock frequency, and 8-pin SOIC package. It supports XIP (execute-in-place), sector erase, and deep power-down mode for low-power embedded applications.
For engineers reviewing the S25FL256LDPNFV011 datasheet, S25FL256LDPNFV011 pinout, S25FL256LDPNFV011 application, or S25FL256LDPNFV011 equivalent, key selection criteria include Quad SPI timing compliance, 1.8 V I/O compatibility, sector protection granularity, and industrial temperature range operation.
Technical Context
This device implements a standard Serial Peripheral Interface (SPI) with extended Quad I/O mode for high-speed read throughput. It uses a 64-byte page programming buffer and supports both uniform 4-KB sectors and 64-KB blocks for flexible firmware partitioning.
The memory array is organized as 512 Kbytes × 64 bits, with hardware write protection via WP# pin and software-controlled block protection. It features a 100,000-cycle endurance rating and 20-year data retention at 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 256 Mbit (32 MB) - sufficient for full bootloader + application firmware in space-constrained MCU systems |
| Interface | Quad SPI (x4 I/O) - enables up to 532 MB/s effective read bandwidth with 133 MHz clock |
| Supply Voltage | 3.0–3.6 V - compatible with standard 3.3 V rail without level-shifting |
| Operating Temperature | −40°C to +105°C - qualified for industrial and automotive under-hood environments |
| Erase Granularity | 4 KB sectors and 64 KB blocks - allows fine-grained firmware updates without full chip erase |
| Write Endurance | 100,000 cycles per sector - supports frequent OTA update cycles in field-deployed devices |
Pinout & Package
Package: 8-pin SOIC (300 mil, PN suffix), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SO/IO1 | Serial Output / Quad I/O 1 | Bi-directional data line for Quad SPI read/write; requires pull-up for standard SPI fallback |
| SI/IO0 | Serial Input / Quad I/O 0 | Input for standard SPI writes; becomes bi-directional in Quad mode |
| WP#/IO2 | Write Protect / Quad I/O 2 | Hardware sector lock control when held low; dual-role pin for Quad I/O expansion |
| HOLD#/IO3 | Hold / Quad I/O 3 | Pauses ongoing transmission without deselecting device; enables multi-master arbitration |
| CS# | Chip Select | Active-low enable for command execution; must be deasserted between commands |
| CLK | Serial Clock | Master-generated clock up to 133 MHz; controls all timing-critical operations |
| VCC | Power Supply | 3.0–3.6 V core and I/O supply; decoupling capacitor required within 10 mm |
| GND | Ground | Reference return path for all signals and power; separate analog/digital ground not required |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI x4 Mode | Enables 4-bit-per-clock data transfer, doubling throughput vs. standard SPI without increasing clock frequency |
| Deep Power-Down Mode | Reduces current draw to 2 µA max, enabling battery-backed systems to retain firmware state for years |
| Program/Erase Suspend | Allows read access during background erase or program, supporting real-time interrupt handling in RTOS environments |
| Security Register Lock | Prevents unauthorized modification of configuration bits (e.g., BP bits, QE bit) after factory programming |
| Reset Pin Support | Hardware reset via dedicated RST# pin ensures deterministic initialization independent of SPI bus state |

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 |
|---|---|---|---|
| S25FL256SDPNFV010 | Same density and package but rated for −40°C to +85°C only; lacks deep power-down mode | Not suitable for under-hood automotive or extended-temperature industrial deployments | Select when cost sensitivity outweighs extended temperature or ultra-low-power requirements |
| MX25L25645GMI-10G | 256 Mbit, 104 MHz max clock, no hardware reset pin, different sector protection scheme | Lacks RST# pin and program/erase suspend - limits use in safety-critical real-time systems | Choose for legacy designs already using Macronix SPI flash footprint and timing margins |

FAQ
What is the maximum clock frequency supported by S25FL256LDPNFV011 in Quad SPI mode?
The device supports up to 133 MHz in Quad SPI mode, delivering 532 MB/s effective read bandwidth. This frequency is validated across the full industrial temperature range and requires controlled impedance PCB routing with matched trace lengths for all four I/O lines to maintain signal integrity.
Does S25FL256LDPNFV011 support execute-in-place (XIP) operation?
Yes, it supports XIP mode via Quad SPI interface, allowing direct code execution from flash without copying to RAM. The device includes cache-line prefetch and wrap-around burst addressing to minimize instruction fetch latency in Cortex-M and R-series microcontrollers.
How is hardware write protection implemented on this device?
Hardware write protection is enabled by pulling the WP# pin low, which locks all sectors with active block protection bits. Protection status is retained across power cycles and cannot be overridden by software commands unless WP# is deasserted first.
Is there a dedicated reset pin, and what is its function?
Yes, the RST# pin provides hardware reset functionality. Asserting RST# forces the device into a known initial state, clearing internal registers and aborting any ongoing program or erase operation-ensuring deterministic recovery after brown-out or system-level faults.
