Infineon Technologies S25FL132K0XBHI033

Overview

S25FL132K0XBHI033 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 108 MHz and delivering up to 54 MB/s continuous data transfer. It features uniform 4 kB sector and 64 kB block erase, 100K program-erase cycles, and 20-year data retention. Used for XIP code execution and firmware storage in space-constrained embedded controllers.

For engineers reviewing the S25FL132K0XBHI033 datasheet, S25FL132K0XBHI033 pinout, S25FL132K0XBHI033 application, or S25FL132K0XBHI033 equivalent, key selection criteria include quad I/O read performance, industrial temperature support (−40 °C to +105 °C), hardware write protection via WP#/HOLD#, security register OTP protection, and migration path to S25FL064L.

Technical Context

This device implements JEDEC-standard SPI command set with full Multi-I/O support-Single, Dual, and Quad I/O modes-all sharing the same 4–6-pin interface (CS#, SCK, IO0–IO3). Clock polarity/phase modes 0 and 3 are supported, and QIO mode disables WP# and HOLD# functions while enabling 4-bit-per-cycle transfers.

It integrates a 90 nm floating gate process, non-volatile status register with software/hardware protection control, three 256-byte OTP security registers, and an 8-byte unique device ID. The memory array supports continuous and wrapped read modes optimized for cache-line refill and execute-in-place operation.

FAQ

Is S25FL132K0XBHI033 recommended for new designs?

No. Cypress explicitly states this part is "Not Recommended for New Design" and has been retired. The factory-recommended migration path is S25FL064L. While existing designs may continue using S25FL132K0XBHI033, new projects should select S25FL064L or other active-family alternatives to ensure long-term supply and technical support.

What package does S25FL132K0XBHI033 use?

S25FL132K0XBHI033 uses an 8-contact USON package (4 mm × 4 mm), designated UNF008 in Cypress documentation. It is RoHS-compliant, halogen-free, and rated MSL3. This compact, leadless package supports automated assembly and provides thermal performance suitable for industrial temperature operation.

Does S25FL132K0XBHI033 support Execute-in-Place (XIP)?

Yes. It supports efficient XIP via Continuous Read and Wrapped Read modes, with Quad Read achieving 54 MB/s - sufficient to match or exceed legacy x16 parallel NOR flash bandwidth. The 108 MHz clock rate and low command overhead enable deterministic instruction fetch timing critical for real-time embedded applications.

How is security implemented in S25FL132K0XBHI033?

Security includes three 256-byte OTP security registers, 8-byte unique device ID, pointer-based block protection, software/hardware write protection (WP#), lock-down until power cycle, and non-volatile status register bits. These features collectively enable secure boot, firmware authentication, and tamper-resistant storage of calibration or cryptographic data.
