Infineon Technologies S25FL064LABBHI030

Overview

S25FL064LABBHI030 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, with uniform 4 KB/32 KB/64 KB erase sectors and 100,000 program-erase cycles - deployed in industrial embedded systems for XIP code execution and firmware storage.

For engineers reviewing the S25FL064LABBHI030 datasheet, S25FL064LABBHI030 pinout, S25FL064LABBHI030 application, or S25FL064LABBHI030 equivalent, key selection criteria include Quad I/O read bandwidth (54 MBps), industrial temperature grade (–40°C to +85°C), SOIC-16 package compatibility, SFDP support for auto-configuration, 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 delivers DDR Quad I/O reads at 54 MBps using dual-edge clock sampling. Its architecture includes a 256-byte page programming buffer and supports suspend/resume for both program and erase operations.

Security is enforced via four 256-byte non-volatile Security Regions outside the main array, with programmable lock-down options including password protection and permanent write-disable for Regions 2/3 and the Pointer Region - all managed through dedicated IRP and Security Region commands.

Equivalent & Alternatives

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

Compared with S25FL064LABBHI030, the Cypress alternative offers identical reliability and feature set with minor factory-default configuration variance, while the Winbond part trades security and DDR capability for broader voltage range and marginally higher clock speed - making it unsuitable for safety-critical firmware storage.

FAQ

What is the default state of the Security Regions after power-on?

Upon power-up, Security Regions 0 and 1 are unlocked and writable; Regions 2 and 3 are locked by default via Status Register Protection bits SRP1/SRP0. The Pointer Region is non-volatile and retains its last programmed protection state across power cycles. No password is required unless explicitly enabled via Write Enable and Security Register commands.

Does S25FL064LABBHI030 support execute-in-place (XIP) operation?

Yes - the device supports continuous burst read mode in both standard SPI and QPI protocols, enabling true XIP execution from flash without copying to RAM. This requires host controller support for QPI command sequences and proper cache coherency handling, but eliminates boot latency associated with load-to-RAM workflows.

Can this part be used in place of older S25FL1-K series devices?

Yes - S25FL064LABBHI030 maintains pin, command, and footprint compatibility with S25FL1-K devices, including identical SOIC-16 pinout and overlapping instruction set. However, it adds DDR read modes, enhanced security features, and improved endurance - requiring firmware validation but no PCB redesign.

What is the maximum clock frequency for DDR Quad I/O read operations?

The maximum supported clock frequency for DDR Quad I/O read is 54 MHz, delivering an effective data rate of 54 MBps (4 bits × 54 MHz × 2 edges/clock). This is specified under VCC = 2.7–3.6 V and industrial temperature conditions, with timing compliance verified per AC characteristics in the official Infineon datasheet Rev. *H.
