Infineon Technologies S25FL064LABMFA010

Overview

S25FL064LABMFA010 from Infineon is a 64 Mb (8 MB) serial NOR flash memory using 65-nm floating gate technology, supporting SPI multi-I/O (SIO/DIO/QIO/QPI) and DDR read modes up to 108 MHz. It delivers up to 54 MBps read throughput, features uniform 4 KB/32 KB/64 KB erase sectors, 256-byte page programming, and operates from 2.7 V to 3.6 V across –40°C to +105°C (Industrial Plus grade). It enables XIP execution and code shadowing in space-constrained embedded systems.

For engineers reviewing the S25FL064LABMFA010 datasheet, S25FL064LABMFA010 pinout, S25FL064LABMFA010 application, or S25FL064LABMFA010 equivalent, key selection criteria include Quad I/O read bandwidth, sector-erase granularity, SFDP-compliant configuration, security region partitioning, and industrial-temperature reliability for boot code storage and firmware update storage.

Technical Context

The S25FL064LABMFA010 implements a serial flash architecture with dual- and quad-I/O command sets compliant with JEDEC JESD216B SFDP v1.6, enabling automatic configuration discovery. Its command set supports burst wrap, continuous XIP mode, and DDR clocking on both edges for QIO/QPI reads.

It integrates four 256-byte Security Regions outside the main array, with non-volatile pointer region control, volatile individual block lock, and power-supply lock-down protection for Security Regions 2–3. Erase and program operations support suspend/resume functionality for real-time system responsiveness.

FAQ

What is the maximum clock frequency supported for Quad I/O read operations?

The S25FL064LABMFA010 supports Quad I/O read commands at up to 108 MHz, delivering 54 MBps throughput. This frequency is validated under industrial-plus temperature conditions and requires proper PCB layout with controlled impedance and matched trace lengths for all four I/O lines.

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

Yes - it supports continuous read mode and burst wrap addressing for true XIP execution. The device includes dedicated QPI and DDR QIO modes optimized for low-latency instruction fetch, and its SFDP table provides configurable latency and dummy cycle parameters for seamless integration with MCU memory controllers.

How are the Security Regions protected from unauthorized access?

Security Regions 2 and 3 can be permanently locked via power-supply lock-down or password protection; Region 0 and 1 support volatile lock. Protection is enforced through Status Register bits SRP0/SRP1 and dedicated commands (SECURE, UNLOCK), with hardware enforcement independent of software state.

Can the device operate reliably at 2.7 V supply voltage?

Yes - the device is fully specified from 2.7 V to 3.6 V across its entire temperature range. At 2.7 V, maximum clock frequency is reduced to 80 MHz for QIO reads, and program/erase times increase by ≤15%, but all functionality including security features remains guaranteed per datasheet limits.
