Infineon Technologies S25FL064LABMFB011

Overview

S25FL064LABMFB011 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. It operates from 2.7 V to 3.6 V, features uniform 4 KB sector erase, 100,000 program-erase cycles, and 20-year data retention, and is qualified for industrial temperature range (–40°C to +85°C). It enables XIP execution and code shadowing in space-constrained embedded systems.

For engineers reviewing the S25FL064LABMFB011 datasheet, S25FL064LABMFB011 pinout, S25FL064LABMFB011 application, or S25FL064LABMFB011 equivalent, this device delivers high-speed Quad I/O read throughput up to 54 MBps at 108 MHz, supports SFDP-based configuration, and integrates four 256-byte Security Regions with non-volatile pointer region and password-protected lock-down.

Technical Context

The S25FL064LABMFB011 implements a serial flash architecture with configurable addressing (24-/32-bit), burst wrap and continuous XIP read modes, and dual-edge DDR transfers for QIO/QPI commands. Its command set includes suspend/resume for both program and erase operations, and it supports JEDEC JESD216B SFDP for runtime parameter discovery.

It uses standard SPI clock modes 0 and 3, provides dedicated IO0–IO3 pins for multi-I/O operation, and integrates status/configuration register protection plus individual sector/block lock via volatile and non-volatile mechanisms - enabling secure firmware storage and field-upgradable boot code management.

FAQ

What is the maximum clock frequency supported in Quad I/O SDR mode?

The S25FL064LABMFB011 supports up to 108 MHz in Quad I/O SDR mode, delivering 54 MBps read throughput. This matches or exceeds legacy parallel NOR performance while using only six signal lines (CS#, SCK, IO0–IO3), making it ideal for pin-constrained SoC interfaces.

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

Yes - the device supports continuous read mode with burst wrap, enabling true XIP execution directly from flash. The internal address counter and QPI command structure eliminate external address latching, reducing CPU wait states and simplifying memory-mapped interface design.

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; the pointer region stores non-volatile lock ranges. Protection is enforced by hardware - no software bypass is possible once enabled, and attempts to write protected regions return status error flags.

Is the SOIC-8 package RoHS-compliant and lead-free?

Yes - the S25FL064LABMFB011 in 8-lead SOIC 208 mil (SOC008) package is fully Pb-free and RoHS-compliant, with matte tin finish on leads and halogen-free molding compound, meeting IPC/JEDEC J-STD-020 moisture sensitivity level 3 requirements.
