Infineon Technologies S25FL064LABMFI013

Overview

S25FL064LABMFI013 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, with industrial temperature range (–40°C to +85°C), supporting SPI single/dual/quad I/O and QPI/DDR read modes up to 108 MHz, and featuring uniform 4 KB sector erase, 256-byte page programming, and security regions for firmware protection - deployed in boot code storage for industrial microcontrollers.

For engineers reviewing the S25FL064LABMFI013 datasheet, S25FL064LABMFI013 pinout, S25FL064LABMFI013 application, or S25FL064LABMFI013 equivalent, key selection criteria include Quad I/O read bandwidth (54 MBps), 100,000 program-erase cycles, SFDP compliance, security region configuration, and SOIC-16 package compatibility with legacy S25FL-A/S25FL1-K footprints.

Technical Context

The S25FL064LABMFI013 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 control during non-volatile write sequences.

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 or password-based protection for Regions 2/3 - all managed via dedicated IRP and Security Region commands per JEDEC JESD216B-compliant SFDP tables.

FAQ

Is S25FL064LABMFI013 pin-compatible with earlier S25FL-A series devices?

Yes - it maintains identical SOIC-16 pinout and command subset compatibility with S25FL-A, S25FL1-K, and S25FL-P families, including identical SI/SO/CS#/WP#/RESET# signal mapping and timing envelopes, enabling drop-in replacement without PCB redesign.

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

Yes - it supports continuous read mode with burst wrap and QPI interface, allowing direct instruction fetch from flash without copying to RAM; verified with ARM Cortex-M7 and RISC-V cores running bare-metal and FreeRTOS bootloaders.

What security mechanisms prevent unauthorized firmware modification?

Hardware-enforced protections include Status Register Protect (SRP0/SRP1), individual 4 KB sector lock bits, four dedicated 256-byte Security Regions with password or power-lock-down, and non-volatile pointer region defining protected address ranges - all accessible only via authenticated commands.

Can S25FL064LABMFI013 operate at 108 MHz in Quad I/O mode?

Yes - datasheet Table 1 specifies 108 MHz maximum clock for Quad Read commands, delivering 54 MBps throughput; operation requires stable 3.3 V supply, controlled impedance PCB routing, and proper termination per Infineon's layout guidelines in AN220012.
