Cypress Semiconductor Corp S25FL132K0XMFV011

Overview

S25FL132K0XMFV011 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, 20-year data retention, and hardware/software write protection - deployed in embedded boot code storage and firmware update applications.

For engineers reviewing the S25FL132K0XMFV011 datasheet, S25FL132K0XMFV011 pinout, S25FL132K0XMFV011 application, or S25FL132K0XMFV011 equivalent, key selection criteria include Quad I/O read performance, industrial temperature support (−40 °C to +105 °C), security register OTP protection, 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 support, enabling compatibility with legacy S25FL-K and FL-P families while adding variable dummy cycle latency for optimized timing. It uses 90 nm floating gate technology and supports Execute-In-Place (XIP) via Continuous and Wrapped Read modes.

The memory integrates three 256-byte one-time-programmable (OTP) security registers, pointer-based block protection, and dual protection mechanisms - software command lock, hardware WP#/HOLD# inputs, and lock-down until power cycle - all configurable across top/bottom memory ranges from 4 kB to full array.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) is a U.S.-based semiconductor company specializing in programmable system-on-chip (PSoC), memory, and USB-C solutions for embedded and industrial markets.

The S25FL1-K family was designed for high-reliability, SPI-based code storage in resource-constrained embedded systems - emphasizing XIP efficiency, security, and industrial temperature resilience over raw density.

FAQ

Is S25FL132K0XMFV011 still in production?

No - Cypress officially retired the S25FL1-K family and does not recommend it for new designs. Production continues only for existing customer commitments under last-time-buy terms. Aetrix maintains limited legacy stock with full traceability and documentation for ongoing maintenance and repair programs.

What is the correct replacement for S25FL132K0XMFV011?

The factory-recommended replacement is S25FL064L0XMFI001: same WSON-8 (5×6 mm) package, pin-compatible, supports identical command set, and adds higher density (64 Mbit), faster Quad Read (133 MHz), and dual-voltage operation. Migration requires minor firmware update for SFDP parsing and voltage configuration.

Does S25FL132K0XMFV011 support Execute-In-Place (XIP)?

Yes - it supports efficient XIP via Continuous Read and Wrapped Read modes, which minimize address setup overhead and cache-line fill latency. At 108 MHz Quad Read, it delivers 54 MB/s sustained bandwidth - sufficient for real-time execution of ARM Cortex-M4/M7 applications without local RAM shadowing.

Can the security registers be reprogrammed after initial write?

No - the three 256-byte security registers are one-time-programmable (OTP). Once written, bits can only be changed from '1' to '0'; further writes are blocked by hardware lock-down until power cycle, and permanent lock bits prevent future modification. This ensures cryptographic keys and device IDs remain immutable after provisioning.
