Infineon Technologies S25FL064LABMFA011

Overview

S25FL064LABMFA011 from Infineon is a 64 Mb (8 MB) serial NOR flash memory 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 automotive instrument clusters and industrial PLCs.

For engineers reviewing the S25FL064LABMFA011 datasheet, S25FL064LABMFA011 pinout, S25FL064LABMFA011 application, or S25FL064LABMFA011 equivalent, key selection criteria include Quad I/O read throughput (54 MBps), 100,000 program-erase cycles, 20-year data retention, AEC-Q100 Grade 2 qualification (–40°C to +105°C), and SOIC-16 package compatibility with legacy S25FL-P/S25FL-S families.

Technical Context

This device implements a serial flash architecture with dual- and quad-I/O command sets compliant with JEDEC JESD216B SFDP, enabling dynamic configuration discovery. It supports both standard SPI clock modes (0 and 3) and DDR-capable QIO/QPI interfaces for high-speed address/data transfer on both clock edges.

The memory array is organized into uniform 4 KB sectors (2048 total), 32 KB half-blocks (256), and 64 KB blocks (128), with independent suspend/resume capability for program and erase operations-critical for real-time firmware updates without system interruption.

FAQ

What is the maximum clock frequency supported in QPI DDR mode?

The S25FL064LABMFA011 supports DDR Quad Read at up to 54 MHz, delivering 54 MBps effective read bandwidth by transferring data on both rising and falling clock edges. This is specified in Table 2 of the datasheet and validated across the full industrial temperature range.

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

Yes, the device supports continuous read mode (XIP) via Fast Read, Dual I/O, Quad I/O, and QPI commands. The memory array is directly executable when mapped into the host processor's address space, with latency optimized for zero-wait-state operation at ≤50 MHz clock rates.

How many security regions are implemented, and what is their physical location?

Four 256-byte Security Regions are implemented outside the main flash array address space, starting at offset 0x00000000 in the Security Regions address map. They are non-volatile, independently lockable, and accessible only via dedicated security commands-not through standard read/write operations.

Is the SOIC-16 package pinout compatible with earlier S25FL-P series devices?

Yes, the SOIC-16 pinout matches S25FL-P series (e.g., S25FL128S), including identical CS#, SCK, IO0–IO3, WP#, RESET#, VCC, and VSS assignments. Functionally, it maintains command-set and footprint compatibility, enabling drop-in replacement where AEC-Q100 Grade 2 qualification is acceptable.
