Infineon Technologies S25FL064LABMFI011

Overview

S25FL064LABMFI011 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 bandwidth via Quad I/O and supports XIP, code shadowing, and reprogrammable data storage in space-constrained embedded systems.

For engineers reviewing the S25FL064LABMFI011 datasheet, S25FL064LABMFI011 pinout, S25FL064LABMFI011 application, or S25FL064LABMFI011 equivalent, key selection considerations include its 4 KB uniform sector erase granularity, 100,000 program-erase cycles, industrial temperature grade (–40°C to +85°C), and SOIC-16 package compatibility with legacy S25FL-A/S25FL1-K families.

Technical Context

The device implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), extended 24-/32-bit addressing, and SFDP-compliant configuration discovery. Its command set includes suspend/resume for both program and erase operations, enabling real-time interrupt handling in multitasking firmware environments.

Security architecture includes four dedicated 256-byte Security Regions outside the main array, non-volatile pointer region for block locking, and power-supply lock-down with password protection for Regions 2/3 - all implemented in hardware without host CPU intervention.

FAQ

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

The S25FL064LABMFI011 supports DDR Quad Read at up to 54 MHz clock frequency, delivering 54 MBps effective read bandwidth by transferring data on both rising and falling edges. This mode requires proper impedance-controlled routing and setup/hold timing compliance per the datasheet's AC characteristics table.

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

Yes, the device supports XIP via Continuous Read mode in Fast Read, Dual I/O, Quad I/O, and QPI configurations. The internal address counter auto-increments during burst reads, enabling seamless instruction fetch directly from flash without intermediate buffering in RAM.

How is hardware write protection implemented on this part?

Hardware write protection uses the WP# pin (IO2) in conjunction with Status Register bits SRP0/SRP1. When WP# is asserted low and SRP bits are set, all program/erase commands are blocked except for volatile register writes. Protection can be configured for entire array, individual sectors, or Security Regions.

Can the Security Regions be accessed independently of the main flash array?

Yes, Security Regions reside in a physically separate 1 KB address space (0x000000–0x0003FF) outside the main 8 MB array. They are accessed via dedicated commands (e.g., Read Security Register, Program Security Region), and their contents remain inaccessible during standard array read/program operations.
