Infineon Technologies S25FL064LABBHA020

Overview

S25FL064LABBHA020 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, 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 S25FL064LABBHA020 datasheet, S25FL064LABBHA020 pinout, S25FL064LABBHA020 application, or S25FL064LABBHA020 equivalent, key selection factors include Quad I/O read throughput up to 54 MBps, 100,000 program-erase cycles, 20-year data retention, AEC-Q100 Grade 2 qualification (–40°C to +105°C), and security region protection for firmware integrity.

Technical Context

The device implements a serial peripheral interface with configurable clock polarity/phase (modes 0 and 3), supports extended addressing (24-/32-bit), and integrates Serial Flash Discoverable Parameters (SFDP) for automatic configuration. Its architecture includes a 256-byte page programming buffer and supports suspend/resume during both program and erase operations.

Security features include four dedicated 256-byte Security Regions outside the main array, non-volatile pointer region for sector/block range locking, and power supply lock-down or password-based protection for Security Regions 2 and 3 - enabling secure boot and firmware update partitioning in safety-critical systems.

FAQ

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

The S25FL064LABBHA020 supports DDR Quad Read at up to 54 MHz, delivering 54 MBps effective bandwidth by transferring data on both rising and falling clock edges. This is specified in Table 2 of the official Infineon datasheet (Rev. *H), and requires proper setup of the Configuration Register to enable DDR mode and QPI protocol.

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

Yes, the S25FL064LABBHA020 supports XIP via Continuous Read mode in Fast Read, Dual I/O, Quad I/O, and QPI protocols. The device includes burst wrap addressing and low-latency read timing to enable direct CPU instruction fetches without copying to RAM, as confirmed in Section 5.4 and Table 8-1 of the datasheet.

How many Security Regions does this part implement, and where are they located?

This device implements four 256-byte Security Regions located outside the main flash array address space, starting at address 0x00000000 in the Security Regions address space. They are accessible only via dedicated security commands (e.g., Read Security Register, Program Security Region) and protected by SRP bits and optional password lock-down, per Sections 7.1 and 8.7 of the datasheet.

Is the SOIC-8 package (BB) RoHS and REACH compliant?

Yes, the S25FL064LABBHA020 uses a Pb-free SOIC-8 package (SOC008) fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Compliance documentation, including material declarations and test reports, is available through Infineon's official product portal under document number 002-12878.
