Product details

Overview

S25FL064LABNFM041 from Infineon is a 64 Mb (8 MB) serial NOR flash memory with SPI multi-I/O interface, 3.0 V single supply, 100,000 program/erase cycles, and 20-year data retention. It supports Quad I/O, QPI, and DDR Quad Read modes up to 54 MBps, and features uniform 4 KB sector erase, security registers, and industrial temperature range (–40°C to +85°C). It is used for XIP code execution and reprogrammable firmware storage in space-constrained embedded systems.

For engineers reviewing the S25FL064LABNFM041 datasheet, S25FL064LABNFM041 pinout, S25FL064LABNFM041 application, or S25FL064LABNFM041 equivalent, key selection criteria include supported I/O modes (SIO/DIO/QIO/QPI), DDR read capability, sector protection granularity, security region configuration, and SOIC-16 package compatibility with legacy S25FL-P/S25FL-S families.

Technical Context

This device implements a floating-gate 65 nm process architecture with a 256-byte page programming buffer and hierarchical erase units: 4 KB sectors, 32 KB half-blocks, 64 KB blocks, and full-chip erase. It supports JEDEC JESD216B SFDP for automatic configuration detection and includes dedicated 256-byte security regions independent of main array.

The SPI-MIO interface operates in clock modes 0 and 3, with configurable address width (24-bit or 32-bit), and supports volatile individual sector lock, nonvolatile pointer region lock, and power-down lockdown via password or permanent protection. Reset# and IO3 share a dual-function terminal enabling hardware reset or quad I/O operation.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Size	64 Mb (8 MB) - sufficient for boot code, firmware images, and parameter storage in resource-limited microcontrollers.
Interface Type	SPI Multi-I/O (SIO/DIO/QIO/QPI) - reduces pin count vs parallel NOR while maintaining high throughput.
Max Read Speed	54 MBps (DDR Quad I/O @ 54 MHz) - enables real-time XIP execution without external RAM buffering.
Erase Granularity	Uniform 4 KB sectors - allows fine-grained firmware updates without disturbing adjacent functional modules.
Data Retention	20 years min - ensures long-term reliability in unattended industrial and automotive control applications.
Endurance	100,000 program/erase cycles - supports frequent field firmware upgrades over product lifetime.
Supply Voltage	2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and tolerant of board-level voltage variation.
Operating Temp	–40°C to +85°C (Industrial Grade) - validated for deployment in factory automation and outdoor edge nodes.

Pinout & Package

Package: 16-lead SOIC (300 mil), RoHS-compliant, surface-mountable with standard reflow profile.

Pin/Terminal	Circuit Role	Design Meaning
CS#	Chip Select	Active-low enable for SPI command decoding; must be asserted before each transaction.
SCK	Serial Clock	Provides timing reference for all I/O operations; supports modes 0 and 3 polarity/phase configurations.
IO0 (SI)	Serial Input / Data Line 0	Primary input for commands and addresses in SIO mode; bidirectional in DIO/QIO/QPI modes.
IO1 (SO)	Serial Output / Data Line 1	Primary output for read data in SIO mode; bidirectional in DIO/QIO/QPI modes.
IO2 (WP#)	Write Protect / Data Line 2	Hardware write-protection when pulled low; functions as QIO data line when WP# disabled via status register.
IO3 / RESET#	Quad I/O / Hardware Reset	Dual-function pin: enables fourth data lane in QIO/QPI or triggers hard reset when asserted low.
VCC	Power Supply	Single 2.7–3.6 V supply for core and I/O; no separate VIO required.
VSS	Ground	Common return path for power and signals; requires low-impedance PCB connection.

Key Features

Feature	Design Value
DDR Quad Read Support	Enables 54 MBps throughput using both clock edges-doubles effective bandwidth without increasing clock frequency.
Four Independent Security Regions	Each 256-byte region is electrically isolated from main array, allowing secure key storage and tamper-resistant boot code partitioning.
Volatile Sector Lock	Permits runtime locking/unlocking of individual 4 KB sectors during firmware update sequences without persistent register writes.
JEDEC JESD216B SFDP Compliance	Allows host MCU to auto-detect memory geometry, timing parameters, and feature set-eliminates hardcoded driver configuration.
Program/Erase Suspend & Resume	Interrupts background erase or program to service urgent read requests, improving real-time system 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
Cypress S25FL064L0XMFI000	Same die, identical electrical specs, but uses WSON-8 (5×6 mm) package instead of SOIC-16.	Preferred where PCB area is constrained and thermal performance favors exposed-pad package.	Select when footprint reduction and improved thermal dissipation outweigh SOIC rework familiarity.
Winbond W25Q64JWIM	64 Mb SPI NOR with 4 KB sectors, but lacks DDR Quad Read and has only 50K endurance cycles.	Suitable for cost-sensitive consumer applications where XIP latency and long-term field updates are less critical.	Choose only if DDR read speed and 100K-cycle endurance are not required in final design.

Compared with S25FL064LABNFM041, the Cypress alternative offers identical functionality in a smaller package, while the Winbond part trades DDR performance and endurance for lower unit cost-making it viable only in non-critical, short-lifecycle deployments.

FAQ

Is S25FL064LABNFM041 pin-compatible with earlier S25FL-P series devices?

Yes, this SOIC-16 variant maintains identical pinout and footprint with S25FL-P and S25FL-S families, including CS#, SCK, IO0–IO3, VCC, and VSS assignments. Command set and register mapping are backward-compatible per JEDEC JESD216B, enabling drop-in replacement in existing designs without layout changes.

Does S25FL064LABNFM041 support hardware reset via the IO3/RESET# pin?

Yes, asserting IO3/RESET# low for ≥20 µs initiates a hardware reset that clears internal state, disables QPI mode, and returns the device to standard SPI mode. This function is independent of software commands and operates even during active program/erase operations.

What is the minimum VCC voltage required for reliable DDR Quad Read operation?

DDR Quad Read is guaranteed functional across the full specified supply range of 2.7 V to 3.6 V. At 2.7 V, AC timing margins remain compliant per datasheet Table 12.5, with tVH and tVH_MIN values maintained under worst-case process/voltage/temperature corners.

Can security regions be programmed independently of the main flash array?

Yes, each of the four 256-byte security regions has dedicated command set (e.g., 42h/44h for program, 48h/4Ch for erase) and separate address space. Programming or erasing them does not affect main array contents, and they retain data through power cycles and full-chip erase operations.
