Infineon Technologies S25FL064LABMFV010

Overview

S25FL064LABMFV010 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 with industrial temperature range (–40°C to +85°C). It supports SPI multi-I/O modes - SIO, DIO, QIO, and QPI - including DDR read commands, delivers up to 54 MBps read throughput, and features uniform 4 KB/32 KB/64 KB erase sectors and 256-byte page programming. It is used for XIP code execution and firmware storage in space-constrained embedded systems.

For engineers reviewing the S25FL064LABMFV010 datasheet, S25FL064LABMFV010 pinout, S25FL064LABMFV010 application, or S25FL064LABMFV010 equivalent, key selection criteria include Quad I/O read performance, SFDP-compliant configuration, sector-erase flexibility, security region protection, and compatibility with legacy S25FL-A/S25FL1-K families.

Technical Context

The S25FL064LABMFV010 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 protocol supports clock polarity modes 0 and 3, DDR read on both clock edges, and extended addressing (24-/32-bit) for >16 MB addressability.

It integrates dedicated hardware for security region management (four 256-byte non-volatile regions outside main array), individual block lock, pointer region control, and power-supply lock-down protection. 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 S25FL064LABMFV010 supports Quad I/O read commands at up to 108 MHz, delivering 54 MBps throughput. This frequency is validated across the full industrial temperature range and requires proper signal integrity layout per Infineon's layout guidelines in section 2.2 of the datasheet. No external PLL or clock multiplier is needed.

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

Yes, the S25FL064LABMFV010 supports continuous read mode (XIP) via Fast Read, Dual I/O, Quad I/O, and QPI commands. The device maintains valid data output across burst wrap boundaries and provides deterministic latency, enabling direct CPU instruction fetch without RAM buffering in supported microcontroller platforms.

How are the four Security Regions physically implemented?

The four 256-byte Security Regions reside in dedicated non-volatile memory cells outside the main 64 Mb flash array, each independently protected by status register bits, WP# pin assertion, or password-controlled lock-down. They are accessed via dedicated commands (e.g., Read Security Register, Program Security Region) and cannot be erased by standard sector/block erase instructions.

Is the SOIC-8 package (SOC008) pinout compatible with earlier S25FL-A series devices?

Yes, the S25FL064LABMFV010 in 8-lead SOIC (SOC008) maintains identical pin assignment and electrical characteristics with S25FL064A and S25FL128A devices. This enables drop-in replacement in existing layouts, provided the host controller firmware supports the extended command set and SFDP parameter parsing introduced in the FL-L family.
