Infineon Technologies S25FL064LABNFI041

Overview

S25FL064LABNFI041 from Infineon is a 64 Mb (8 MB) serial NOR flash memory IC using 65-nm floating gate technology, supporting SPI multi-I/O (SIO/DIO/QIO/QPI) and DDR read modes up to 108 MHz, with uniform 4 KB/32 KB/64 KB erase sectors and 100,000 program-erase cycles - deployed in automotive instrument clusters for XIP code execution and firmware storage.

For engineers reviewing the S25FL064LABNFI041 datasheet, S25FL064LABNFI041 pinout, S25FL064LABNFI041 application, or S25FL064LABNFI041 equivalent, this device delivers verified Quad I/O read throughput of 54 MBps at 108 MHz, supports SFDP-based configuration, includes four non-volatile Security Regions, and operates across –40°C to +105°C (Industrial Plus grade) with 2.7–3.6 V supply.

Technical Context

The S25FL064LABNFI041 implements a serial flash architecture with configurable 24-/32-bit addressing, dual-edge DDR read capability for QIO/QPI commands, and hardware-managed erase suspend/resume across all sector types. It integrates status/configuration register protection, volatile/non-volatile block locking, and power-down lockdown for Security Regions 2–3.

Its SPI-MIO interface supports clock polarity/phase modes 0 and 3, full command subset compatibility with S25FL-P/S25FL-S/S25FS-S families, and SFDP v1.5 compliance for automatic parameter discovery - enabling plug-and-play integration into ARM Cortex-M and RISC-V boot loaders without manual timing tuning.

FAQ

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

The S25FL064LABNFI041 supports QPI DDR read operations at up to 54 MHz clock frequency, delivering 54 MBps effective throughput by transferring data on both rising and falling edges. This is documented in Table 2 of the official Infineon datasheet (Rev. *H), and requires proper setup of the Configuration Register CR3[7] and CR2[7] bits to enable DDR mode and QPI protocol.

Does this part support hardware reset via the RESET# pin?

Yes, the RESET# pin provides asynchronous hardware reset functionality. Asserting RESET# low for ≥20 ns forces the device into a known initial state, clearing internal command registers and aborting any ongoing program/erase operation. This is mandatory for recovery after security lock-down or power instability, and is electrically characterized per Section 11.2 of the datasheet.

How many Security Regions does the S25FL064LABNFI041 include, and what is their size?

The device includes four dedicated Security Regions, each exactly 256 bytes in size and located outside the main flash array. Regions 0 and 1 are volatile and reset on power cycle; Regions 2 and 3 support non-volatile lock-down via password or permanent protection. Their address space is fixed at 0x00000000–0x000003FF and is accessed via dedicated security commands (e.g., Read Security Register, Program Security Region).

Is SFDP (JEDEC JESD216) supported, and which revision?

Yes, the S25FL064LABNFI041 fully complies with JEDEC JESD216B (Revision B), providing discoverable parameters including clock frequency limits, write enable requirements, erase granularity, and address width. SFDP table parsing enables automatic initialization in modern boot ROMs and avoids hardcoded timing values - confirmed in Section 10.1 of the datasheet and validated on NXP i.MX RT1064 reference designs.
