Infineon Technologies S25FL064LABMFV003

Overview

S25FL064LABMFV003 from Infineon is a 64 Mb (8 MB) serial NOR flash memory IC using 65-nm floating gate technology, operating from 2.7 V to 3.6 V, supporting SPI multi-I/O (SIO/DIO/QIO/QPI), DDR read modes, and uniform 4 KB/32 KB/64 KB erase sectors. It enables XIP execution and code shadowing in space-constrained embedded systems such as industrial HMIs and automotive infotainment boot storage.

For engineers reviewing the S25FL064LABMFV003 datasheet, S25FL064LABMFV003 pinout, S25FL064LABMFV003 application, or S25FL064LABMFV003 equivalent, key selection criteria include Quad I/O read bandwidth up to 54 MBps, 100,000 program-erase cycles, 20-year data retention, industrial temperature grade (–40°C to +85°C), and SOIC-16 package compatibility with legacy S25FL-A/S25FL1-K families.

Technical Context

The S25FL064LABMFV003 implements a serial flash architecture with configurable 24-/32-bit addressing, SFDP v1.6 compliance for auto-configuration, and dual-mode SPI interface supporting clock polarity/phase modes 0 and 3. Its command set includes suspend/resume for both program and erase operations, enabling real-time system responsiveness during non-volatile updates.

Security is enforced via four dedicated 256-byte Security Regions outside the main array, with non-volatile pointer region control, volatile individual sector lock, and power-supply lock-down or password protection for Regions 2–3 - all managed through dedicated IRP and Security Region commands per JEDEC JESD216B.

FAQ

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

The S25FL064LABMFV003 supports up to 108 MHz in Quad I/O SDR mode, delivering 54 MBps read bandwidth. In DDR Quad I/O mode, it operates at up to 54 MHz clock frequency with data sampled on both edges, achieving the same 54 MBps throughput while reducing EMI and timing margin pressure on the host controller.

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

Yes, the S25FL064LABMFV003 supports continuous read mode for XIP operation, allowing microcontrollers to fetch and execute code directly from flash without copying to RAM. This requires host SPI controller support for wrap-around burst reads and proper cache coherency handling, especially when mixing XIP with data writes to other memory regions.

How many Security Regions does the device provide, and what is their physical location?

The device provides four dedicated 256-byte Security Regions located outside the main 8 MB flash array, starting at address 0x7F0000. Each region can be independently locked using volatile or non-volatile methods, and Regions 2 and 3 support additional protection via power-supply lock-down or password authentication to prevent unauthorized access during service or debug sessions.

Is the SOIC-16 package footprint compatible with earlier S25FL-A series devices?

Yes, the SOIC-16 package (SO3016) of S25FL064LABMFV003 maintains pin-to-pin and command-set compatibility with S25FL-A series devices, including identical CS#, SCK, SI/SO, WP#, and RESET# assignments. This allows drop-in replacement in existing designs, provided the host firmware supports extended addressing and newer security features introduced in the FL-L family.
