Product details
Overview
S25FL132K0XMFV043 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 (54 MB/s), uniform 4 kB sector and 64 kB block erase, and 100K program-erase cycles. It operates across –40 °C to +105 °C (Industrial Plus), features three 256-byte OTP security registers, 8-byte unique ID, and Execute-In-Place (XIP) capability for embedded code storage in microcontroller boot applications.
For engineers reviewing the S25FL132K0XMFV043 datasheet, S25FL132K0XMFV043 pinout, S25FL132K0XMFV043 application, or S25FL132K0XMFV043 equivalent, key selection criteria include quad-speed read performance, hardware/software write protection flexibility, security register configurability, and compatibility with legacy S25FL-K footprint and command set in space-constrained industrial control and automotive infotainment systems.
Technical Context
The S25FL132K0XMFV043 implements a 90 nm floating-gate NOR architecture with SPI Multi-I/O (SIO/DIO/QIO) support, enabling configurable data widths using IO0–IO3 pins. Its command set includes Fast Read (0Bh), Dual Read (3Bh), Quad Read (6Bh), Page Program (02h), and Sector/Block Erase (20h/D8h), all compliant with JEDEC JESD216B SFDP for automatic parameter discovery.
It integrates volatile and non-volatile configuration registers, supports program/erase suspend-resume, and provides dual protection mechanisms: software-controlled status register bits and hardware WP#/HOLD# inputs - with QIO mode disabling WP#/HOLD# functionality per JEDEC SPI specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 Mbyte) - sufficient for firmware images up to ~3.8 MiB with overhead, typical for MCU boot code and configuration data. |
| Read Throughput | 54 MB/s (Quad Read @ 108 MHz) - matches parallel NOR bandwidth while reducing I/O count from 16+ to 6 pins. |
| Erase Granularity | Uniform 4 kB sectors and 64 kB blocks - enables fine-grained firmware updates without full chip erase. |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - validated for long-life industrial deployments with frequent field updates. |
| Supply Voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and tolerant of brown-out conditions down to 2.6 V in extended temp range. |
| Temperature Range | –40 °C to +105 °C (Industrial Plus) - qualified for under-hood automotive ECUs and industrial PLCs without derating. |
| Security Features | Three 256-byte OTP security registers + pointer-based protection - enables secure key storage and immutable boot loader verification. |
Pinout & Package
Package: 8-contact USON (4 mm × 4 mm), RoHS-compliant, moisture-sensitive level 3 (MSL3), lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select (active-low) | Enables SPI communication; must be asserted low for entire command sequence including address and data phases. |
| SCK | Serial Clock input | Drives all timing; supports modes 0 and 3 (CPOL=0/1, CPHA=0/1); max 108 MHz for Quad Read. |
| IO0 (SI) | Serial Input / Quad I/O 0 | Input for SIO/DIO commands; bidirectional in DIO/QIO; carries instruction, address, and data in QIO mode. |
| IO1 (SO) | Serial Output / Quad I/O 1 | Output for SIO/DIO reads; bidirectional in DIO/QIO; transmits status, ID, and memory data in QIO mode. |
| IO2 (WP#) | Write Protect / Quad I/O 2 | Hardware write lock when low; disabled in QIO mode; enables sector-level protection independent of software commands. |
| IO3 (HOLD#) | Hold / Quad I/O 3 | Suspends ongoing command (read/program/erase) on any clock edge; disabled in QIO mode. |
| VCC | Core and I/O supply | Single 2.7–3.6 V rail powers logic and I/O buffers; no separate VCCQ required. |
| VSS | Ground | Common reference for all signals; requires low-inductance connection to minimize noise during high-speed reads. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read (6Bh) at 108 MHz | 54 MB/s sustained throughput enables real-time XIP execution of ARM Cortex-M4/M7 firmware without external RAM buffering. |
| Program/Erase Suspend-Resume | Allows background erase to pause during high-priority read access - critical for deterministic response in real-time OS environments. |
| JEDEC JESD216B SFDP | Self-describing parameter table eliminates hard-coded timing values in host bootloader, simplifying porting across flash vendors. |
| OTP Security Registers (3 × 256 B) | Immutable storage for cryptographic keys, device certificates, and secure boot hashes - prevents runtime tampering or cloning. |
| Top/Bottom Block Protection | Configurable 4 kB–full-memory lock ranges via status register or hardware WP#, enabling flexible firmware partitioning (e.g., protected bootloader + updatable app). |
Applications
| Industrial PLC Firmware Storage | Automotive Infotainment Boot Memory |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064L0XMFV043 | 64 Mbit density, 133 MHz Quad Read (66.5 MB/s), 65 nm process, enhanced SFDP v1.6, supports octal DTR mode (not supported by S25FL132K) | Higher density and speed; targets next-gen designs requiring larger firmware footprints and faster boot times | Select for new designs needing >32 Mbit capacity or future-proofing against obsolescence; not pin-compatible due to different package pinout (WSON-8 vs USON-8). |
| MX25L3233FZNI-10G | 32 Mbit, 104 MHz Quad Read (52 MB/s), 65 nm, single 2.7–3.6 V supply, no OTP security registers, no HOLD#/WP# dual-function pins | Lacks hardware write protection and security registers; suitable for cost-sensitive consumer applications without security requirements | Choose only where security and industrial temperature are non-critical; requires redesign of protection logic and lacks SFDP auto-configuration. |
Compared with S25FL132K0XMFV043, S25FL064L offers higher density and speed but requires PCB layout change, while MX25L3233F sacrifices security and suspend-resume for lower cost - making S25FL132K optimal for legacy-compatible, security-aware industrial upgrades.

FAQ
Is S25FL132K0XMFV043 still recommended for new designs?
No - Cypress explicitly states this part is "Not Recommended for New Design" and recommends migrating to S25FL064L. However, it remains actively stocked and supported for legacy design refreshes, repair, and continuity programs where footprint and command compatibility are mandatory.
What package does S25FL132K0XMFV043 use, and is it RoHS-compliant?
S25FL132K0XMFV043 uses an 8-contact USON package (4 mm × 4 mm, UNF008), with lead-free terminations and RoHS compliance confirmed in Cypress's official packaging documentation and material declarations.
Does this device support Execute-In-Place (XIP) reliably at high temperature?
Yes - the device guarantees Quad Read at 108 MHz across –40 °C to +105 °C, and its Continuous Read Mode with low command overhead (≤8 clocks) ensures deterministic XIP latency even under thermal stress, validated per Industrial Plus qualification testing.
How is security implemented, and can the OTP registers be reprogrammed?
Security relies on three 256-byte OTP registers (one-time programmable), 8-byte unique ID, and pointer-based block protection. Once programmed, OTP bits cannot be reset or rewritten - they provide immutable storage for keys and certificates, enforced by internal fuse logic and voltage-lock mechanisms.
