Product details

Overview

S25FL256LDPNFV010 from Infineon Technologies is a 256-Mbit serial NOR flash memory with quad SPI interface, 1.8 V supply voltage, 133 MHz read clock frequency, and uniform 4-KB sector erase capability. It serves as nonvolatile program/data storage in microcontroller-based embedded systems requiring fast boot code execution.

For engineers reviewing the S25FL256LDPNFV010 datasheet, S25FL256LDPNFV010 pinout, S25FL256LDPNFV010 application, or S25FL256LDPNFV010 equivalent, key selection criteria include quad I/O read throughput, sector protection granularity, write suspend/resume support, 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 data transfer. It supports both single- and quad-I/O read commands, with configurable dummy cycles and latency tuning for optimal timing alignment in host systems.

Internal architecture includes a 256-Mbit array organized as 512 uniform 4-KB sectors, with hardware-based write protection via WP# pin and software-controlled block protection registers. Erase suspend/resume enables background operations during active reads.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	256 Mbit (32 MB), sufficient for full firmware images and configuration tables in resource-constrained edge nodes
Interface	Quad SPI (x4 I/O), enabling up to 532 MB/s effective read bandwidth at 133 MHz clock
Supply Voltage	1.7–1.95 V, compatible with low-power 1.8 V system rails and reducing I/O power consumption
Erase Granularity	Uniform 4-KB sectors, allowing fine-grained firmware updates without disturbing adjacent code sections
Operating Temperature	−40°C to +105°C, qualified for industrial and automotive under-hood applications
Write Cycle Endurance	100,000 program/erase cycles per sector, supporting field-upgradable firmware over product lifetime

Pinout & Package

Supplied in an 8-pin SOIC (208-mil) package with standard SPI pin assignment and no exposed pad.

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 program/erase in quad mode
SI/IO0	Serial Input / Quad I/O Line 0	Input-only during standard SPI; becomes bi-directional I/O0 in quad mode for address/data transfer
WP#/IO2	Write Protect / Quad I/O Line 2	Hardware write protection when pulled low; functions as IO2 in quad I/O commands
HOLD#/IO3	Hold Input / Quad I/O Line 3	Pauses ongoing serial communication; serves as IO3 in quad mode for parallel data access
CLK	Serial Clock Input	Master-generated clock synchronizing all SPI transactions; supports up to 133 MHz frequency
CS#	Chip Select Input	Active-low enable signal initiating all device operations; required for command decoding and bus arbitration
VCC	Power Supply	1.8 V core and I/O supply; decoupling capacitor placement critical for stable high-speed read performance
GND	Ground Reference	Common return path for all internal circuitry and I/O signals; requires low-impedance PCB connection

Key Features

Feature	Design Value
Quad I/O Read Mode	Enables 4-bit-per-clock data transfer, doubling bandwidth versus dual I/O and quadrupling versus standard SPI
Program/Erase Suspend	Allows interrupting a sector erase or page program to service a high-priority read request, improving real-time responsiveness
Security Register Lock	One-time programmable lock bit prevents modification of security registers containing unique ID and protection settings
Individual Sector Protection	Software-configurable lock bits per 4-KB sector enable selective write protection for bootloader, config, and application regions
Reset Pin Support	Dedicated RESET# pin allows hardware-initiated device reset independent of CS# deassertion sequence

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	3.0 V supply range, same density and quad SPI interface, but lacks reset pin and has different sector protection scheme	Targeted at legacy 3.3 V industrial systems; not suitable for 1.8 V rail designs	Select only if system uses 3.0–3.6 V supply and does not require hardware reset functionality
MX25L25645GMI-10G	1.8 V operation and quad SPI, but rated only to +85°C and offers no program/erase suspend feature	Applicable in commercial-temperature consumer electronics, not industrial or automotive deployments	Choose only for cost-sensitive, non-automotive applications where suspend/resume is unnecessary

Compared with S25FL256SAGMFV000 and MX25L25645GMI-10G, the S25FL256LDPNFV010 uniquely combines 1.8 V operation, industrial temperature range, hardware reset, and program/erase suspend-critical for real-time embedded systems requiring robust field updates and thermal resilience.

FAQ

What is the maximum clock frequency supported in quad I/O read mode?

The S25FL256LDPNFV010 supports up to 133 MHz in quad I/O read mode, delivering up to 532 MB/s effective throughput. This frequency is validated across the full industrial temperature range (−40°C to +105°C) and requires proper PCB layout with matched trace lengths and controlled impedance.

Does this device support execute-in-place (XIP) operation?

Yes, the S25FL256LDPNFV010 supports XIP mode via its continuous read command with wrap-around addressing. Host processors can directly fetch instructions from flash without copying to RAM, reducing boot latency and memory footprint in space-constrained designs.

How is sector protection configured-hardware or software?

Sector protection is configurable via both hardware and software methods: the WP# pin provides global write protection when asserted, while software commands set individual 4-KB sector lock bits stored in volatile and nonvolatile registers, enabling flexible, granular firmware partitioning.

Is there a dedicated reset pin, and what is its function?

Yes, the RESET# pin provides hardware-initiated device reset independent of chip select deassertion. It restores internal state machines, clears status registers, and resets command sequences-essential for recovery after brown-out or watchdog timeout events in safety-critical systems.
