Infineon Technologies S25FL064LABNFM013

Overview

S25FL064LABNFM013 from Infineon is a 64 Mb (8 MB) serial NOR flash memory using 65-nm floating gate technology, operating from 2.7 V to 3.6 V, supporting SPI multi-I/O (SIO/DIO/QIO/QPI) and DDR read modes up to 108 MHz, with uniform 4 KB sector erase and 100,000 program-erase cycles - deployed in automotive instrument clusters for XIP code execution.

For engineers reviewing the S25FL064LABNFM013 datasheet, S25FL064LABNFM013 pinout, S25FL064LABNFM013 application, or S25FL064LABNFM013 equivalent, key selection factors include Quad I/O read bandwidth (54 MBps), industrial-plus temperature grade (–40°C to +105°C), security region protection, SFDP compliance, and SOIC-16 package compatibility.

Technical Context

The S25FL064LABNFM013 implements a serial flash architecture with configurable 24-/32-bit addressing, supporting both standard SPI command subsets and extended QPI/DDR protocols. Its page programming buffer enables 256-byte atomic writes, while erase suspend/resume allows background operation during real-time system tasks.

Security is enforced via four dedicated 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 regions 2–3 - all managed through dedicated IRP and Security Region commands per JEDEC JESD216B.

FAQ

Does S25FL064LABNFM013 support execute-in-place (XIP) operation?

Yes, it supports XIP via Continuous Read mode in QPI and Fast Read modes with burst wrap addressing. The device delivers deterministic latency under 50 ns for sequential instruction fetches, enabling direct code execution without RAM shadowing in microcontrollers with QPI-capable SPI peripherals.

What is the function of the IO3/RESET# pin in normal operation?

In normal operation with QPI enabled, IO3 functions as the fourth data I/O lane (IO3) for Quad I/O and QPI commands. When RESET# is asserted (low), it forces the device into hardware reset state, clearing internal registers and terminating ongoing commands - required before re-initializing after power-up or brownout recovery.

How does the Security Region protection differ from standard Status Register protection?

Security Regions provide physically isolated 256-byte memory zones outside the main array, each with independent lock bits (volatile/non-volatile), power-supply lock-down, and password protection - unlike Status Register protection, which only guards the entire array or uniform blocks via SRP0/SRP1 bits and lacks per-zone granularity or hardware enforcement.

Is SOIC-16 pinout compatible with earlier S25FL-A series devices?

Yes, the SOIC-16 pinout matches S25FL-A series (e.g., S25FL128A) for CS#, SCK, IO0–IO3, VCC, and VSS. However, S25FL064LABNFM013 adds enhanced QPI/DDR command support and Security Regions - firmware must be updated to leverage new features, though basic SIO read/write remains backward-compatible.
