Infineon Technologies S25FL064LABBHB020

Overview

S25FL064LABBHB020 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 sector erase, 100,000 program-erase cycles, and industrial temperature range (–40°C to +85°C), deployed in embedded boot code storage and XIP applications.

For engineers reviewing the S25FL064LABBHB020 datasheet, S25FL064LABBHB020 pinout, S25FL064LABBHB020 application, or S25FL064LABBHB020 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 enables suspend/resume for both program and erase operations in space-constrained industrial systems.

Technical Context

The S25FL064LABBHB020 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) v1.6 for automatic configuration. It uses a 256-byte page programming buffer and supports burst wrap and continuous XIP read modes.

Its erase architecture provides uniform granularity across 4 KB sectors, 32 KB half-blocks, and 64 KB blocks, all with suspend/resume capability. Security is enforced via Status/Configuration Register protection, volatile individual block lock, and non-volatile pointer region control over protected address ranges.

FAQ

What package type does S25FL064LABBHB020 use?

This part uses an 8-lead SOIC package with 208 mil body width (SOC008), Pb-free and RoHS-compliant. It features gull-wing leads and is compatible with standard surface-mount reflow profiles. The pinout matches industry-standard SPI flash footprints, enabling drop-in replacement in existing PCB layouts designed for similar SOIC-8 serial flash devices.

Does S25FL064LABBHB020 support execute-in-place (XIP) operation?

Yes, it supports continuous XIP mode via Fast Read, Dual I/O, Quad I/O, and QPI commands, with burst wrap addressing for seamless instruction streaming. The device maintains low read latency even at 108 MHz clock rates, and its SFDP table explicitly defines XIP-compatible command sequences and timing parameters required for reliable direct code execution from flash.

How is security implemented in S25FL064LABBHB020?

Security is implemented through four dedicated 256-byte non-volatile Security Regions outside the main array, plus Status/Configuration Register protection, individual sector/block lock, and a pointer region defining protected address ranges. Power supply lock-down and password-based protection prevent unauthorized access to Security Regions 2 and 3 and the pointer region, meeting requirements for secure boot and key storage.

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

The maximum clock frequency for DDR Quad I/O reads is 54 MHz, 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), and the device guarantees setup/hold timing compliance at this rate under industrial temperature and voltage conditions (2.7–3.6 V, –40°C to +85°C).
