Infineon Technologies S25FL064LABBHA023

Overview

S25FL064LABBHA023 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 sector erase, 100,000 program-erase cycles, and industrial temperature range (–40°C to +85°C), deployed in embedded boot code storage and XIP firmware execution.

For engineers reviewing the S25FL064LABBHA023 datasheet, S25FL064LABBHA023 pinout, S25FL064LABBHA023 application, or S25FL064LABBHA023 equivalent, key selection considerations include Quad I/O read bandwidth (54 MBps), SFDP support for auto-configuration, security region protection, 2.7–3.6 V single supply operation, and WSON 5 × 6 mm package compatibility with space-constrained PCB layouts.

Technical Context

The S25FL064LABBHA023 implements a serial flash architecture with configurable addressing (24-/32-bit), burst wrap and continuous XIP read modes, and dual-edge DDR clocking for QIO/QPI commands. Its command set includes suspend/resume for both program and erase operations, enabling real-time host task interleaving.

It integrates four 256-byte Security Regions outside the main array, with non-volatile pointer region control, volatile individual block lock, and power-supply lock-down options for secure firmware update partitions. The device uses JEDEC JESD216B-compliant SFDP for runtime parameter discovery without hard-coded initialization.

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial NOR flash memory applications.

Compared with S25FL064LABBHA023, the SOIC alternative trades compactness for assembly flexibility, while the Winbond part sacrifices security architecture and retention for lower voltage operation-neither matches the combined industrial-grade endurance, integrated security, and WSON footprint of the Infineon device.

FAQ

What is the maximum clock frequency supported in Quad I/O mode?

The S25FL064LABBHA023 supports up to 108 MHz in standard Quad I/O mode, delivering 54 MBps read throughput. In DDR Quad I/O mode, it operates at up to 54 MHz clock frequency with double-edge sampling, achieving the same 54 MBps rate while reducing EMI and timing margin pressure on the host controller.

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

Yes, the S25FL064LABBHA023 supports continuous XIP mode via Fast Read, Dual I/O, Quad I/O, and QPI commands. It includes burst wrap addressing and configurable latency cycles (via SFDP or status register) to align with host bus timing requirements for zero-wait-state execution directly from flash memory.

How are the Security Regions protected from unauthorized access?

Security Regions 2 and 3 can be permanently locked via power-supply lock-down or password protection; Region 0 and 1 support volatile individual lock. Protection is enforced through Status Register bits (SRP0/SRP1), WP# pin assertion, and dedicated commands like Write Security Register, with all regions mapped outside the main flash array to prevent accidental overwrite.

Is the WSON 5 × 6 mm package RoHS and REACH compliant?

Yes, the WSON package for S25FL064LABBHA023 is Pb-free and fully compliant with RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Infineon confirms compliance in its material declaration documents, and the device carries the "Pb-free" marking per JEDEC Standard J-STD-609.
