Infineon Technologies S25FL132K0XNFV041

Overview

S25FL132K0XNFV041 from Cypress Semiconductor is a 32-Mbit (4 Mbyte), 3.0 V serial NOR flash memory with SPI Multi-I/O interface, supporting Quad Read at up to 108 MHz and 54 MB/s continuous data transfer. It features uniform 4 kB sector and 64 kB block erase, 100K program-erase cycles, 20-year data retention, and hardware/software write protection. Used for XIP code execution and firmware storage in industrial microcontroller boot systems.

For engineers reviewing the S25FL132K0XNFV041 datasheet, S25FL132K0XNFV041 pinout, S25FL132K0XNFV041 application, or S25FL132K0XNFV041 equivalent, key selection criteria include Quad I/O timing compliance, AEC-Q100 Grade 2 qualification (–40°C to +105°C), SOIC-8 (208 mil) package compatibility, and security register OTP configuration support.

Technical Context

This device implements JEDEC-standard SPI command set with extended Multi-I/O modes (Single/Dual/Quad), enabling flexible interface width selection without changing physical pin count. Its internal architecture includes a 256-byte page buffer, SFDP v1.5-compliant parameter table, and dual-status registers for volatile/non-volatile configuration control.

Security logic integrates three 256-byte OTP registers, pointer-based block protection, and eight-byte unique ID per die. The 90 nm floating gate process supports operation across Industrial Plus (–40°C to +105°C) and automotive AEC-Q100 Grade 2 temperature ranges with supply voltage from 2.6 V to 3.6 V.

FAQ

What is the maximum clock frequency supported in Quad Read mode?

The S25FL132K0XNFV041 supports up to 108 MHz in Quad Read mode across its full Industrial Plus temperature range (–40°C to +105°C), delivering 54 MB/s sustained throughput. This rating is validated per AC Electrical Characteristics section of the official datasheet (Document 002-00497 Rev. *F), with timing margins maintained under worst-case VCC (2.6 V) and temperature conditions.

Does this part support Execute-In-Place (XIP) directly from flash?

Yes - the device supports efficient XIP via Continuous Read and Wrapped Read modes, which minimize address setup overhead and enable cache-line-aligned burst reads. These modes are enabled via specific command sequences (0xEB for Quad Continuous Read) and require host controller SPI peripheral support for dummy cycle insertion and mode bit configuration.

How many unique security registers does S25FL132K0XNFV041 provide, and what is their protection mechanism?

It provides three 256-byte Security Registers, each protected by One-Time-Programmable (OTP) fuses. Once programmed, contents cannot be altered. Protection is enforced at the silicon level: writes to these registers require both software command (42h) and hardware WP# deassertion, and OTP locking occurs after final byte programming - verified by Status Register bit SRP0/SRP1.

Is the SOIC-208 package (SOC008) lead-free and RoHS compliant?

Yes - the S25FL132K0XNFV041 in SOIC-208 mil package (ordering code suffix 'V041') is fully RoHS-compliant and lead-free, meeting JEDEC J-STD-020D moisture sensitivity level 3 and IPC/JEDEC J-STD-033 handling requirements. The device carries the "Pb-Free" marking on the top-side laser etch and complies with EU Directive 2011/65/EU Annex II exemptions.
