Cypress Semiconductor Corp S25FL132K0XNFIQ10

Overview

S25FL132K0XNFIQ10 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, and 20-year data retention. Used for code execution-in-place (XIP), firmware storage, and boot code in space-constrained embedded systems.

For engineers reviewing the S25FL132K0XNFIQ10 datasheet, S25FL132K0XNFIQ10 pinout, S25FL132K0XNFIQ10 application, or S25FL132K0XNFIQ10 equivalent, key selection considerations include quad I/O timing compliance, security register OTP protection, industrial-plus temperature support (−40 °C to +105 °C), and migration path to S25FL064L for new designs.

Technical Context

This device implements JEDEC-standard SPI command set with modes 0 and 3 clock polarity/phase, supporting Normal, Fast, Dual, and Quad Read protocols. Its 90 nm floating gate architecture enables single-supply operation from 2.6 V to 3.6 V across industrial-plus temperature range.

The memory includes three 256-byte one-time-programmable (OTP) security registers, pointer-based block protection, 8-byte unique ID, and volatile/non-volatile configuration options. SFDP (JEDEC JESD216B) allows host auto-discovery of device capabilities without hard-coded parameters.

FAQ

Is S25FL132K0XNFIQ10 still recommended for new designs?

No. Cypress explicitly states this part is "Not Recommended for New Design" and designates S25FL064L as the factory-recommended migration path. While fully functional and supported for existing production, new projects should adopt S25FL064L for guaranteed long-term availability, enhanced specs, and active technical support.

What package does S25FL132K0XNFIQ10 use, and is it RoHS-compliant?

S25FL132K0XNFIQ10 uses an 8-contact WSON package (5 mm × 6 mm, code WND008), with lead-free, RoHS-compliant construction and moisture sensitivity level 3. The package supports reflow soldering per J-STD-020 and is qualified for industrial-plus temperature operation.

Does this device support Execute-In-Place (XIP), and what enables efficient XIP performance?

Yes. Efficient XIP is enabled by Continuous Read Mode (8-clock overhead per access) and Wrapped Read Mode (cache-line optimized refill). Combined with 108 MHz Quad Read and 54 MB/s throughput, it delivers deterministic instruction fetch latency comparable to parallel NOR, eliminating need for RAM shadowing in many Cortex-M applications.

How is security implemented, and can the OTP registers be reprogrammed?

Security includes three 256-byte OTP registers (irreversible once programmed), hardware WP#/HOLD# pins, software command protection, and lock-down until power cycle. OTP registers are permanently programmed using dedicated commands (e.g., 0x42); no field reprogramming is possible - they are intended for immutable keys, calibration data, or device identity.
