Infineon Technologies S25FL064LABMFN013

Overview

S25FL064LABMFN013 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 throughput, features uniform 4 KB sector erase, 256-byte page programming, and operates from 2.7 V to 3.6 V across –40°C to +105°C industrial-plus temperature range. It is used for XIP code execution and firmware storage in space-constrained embedded controllers.

For engineers reviewing the S25FL064LABMFN013 datasheet, S25FL064LABMFN013 pinout, S25FL064LABMFN013 application, or S25FL064LABMFN013 equivalent, key selection criteria include Quad I/O read bandwidth, 4 KB sector granularity, SFDP support, security region configuration, and SOIC-16 package compatibility with legacy SPI flash footprints.

Technical Context

The device implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), supports both SDR and DDR command execution on QIO/QPI buses, and uses JEDEC JESD216B-compliant SFDP for runtime configuration discovery. Its architecture includes dedicated status/configuration registers with SRP0/SRP1 protection bits and four independent 256-byte Security Regions outside the main array.

Erase operations are fully suspend/resume capable at sector (4 KB), half-block (32 KB), block (64 KB), and chip levels; program operations leverage a 256-byte page buffer with suspend/resume functionality. Power management includes Deep Power Down mode (2 µA) and separate standby currents for SPI (20 µA) and QPI (35 µA) interfaces.

FAQ

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

The S25FL064LABMFN013 supports DDR Quad Read 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 datasheet (Rev. *H, p.3) and requires proper setup of the Configuration Register CR3[7] and CR2[7] bits to enable DDR mode and QPI operation.

Does this part support 32-bit addressing for >16 MB memory maps?

Yes, the device supports extended 32-bit addressing via the 4-byte address instruction (0x13), enabling access beyond the 16 MB boundary. This is configured through the Extended Address Register (EAR) and is required when using more than 24 address bits. The SFDP v1.6 table explicitly declares 32-bit address support, and the default state after power-up is 24-bit mode for backward compatibility.

How is hardware write protection implemented on the SOIC-16 package?

Hardware write protection is enabled by pulling the WP# (Pin 7) low, which locks the top/bottom 4 KB sectors or entire array depending on Status Register bits SRWD and SEC. When WP# is asserted, all program and erase commands are ignored unless the Write Enable Latch (WEL) bit is first set and SRWD/SEC are configured accordingly. Pin 7 functions as IO2 in QIO/QPI modes, so WP# behavior is disabled during multi-I/O operation.

Can the Security Regions be used to store cryptographic keys without risk of overwrite during firmware updates?

Yes, the four 256-byte Security Regions reside outside the main flash array and are protected independently via Status Register bits and password-controlled lock-down. Once permanently locked (via Power Supply Lock-Down or password), they cannot be erased or programmed-even during chip erase-ensuring cryptographic keys remain isolated and immutable during routine firmware updates to the main array.
