Product details
Overview
S25FL132K0XNFV040 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) and features three 256-byte OTP security registers, 8-byte unique ID, and hardware/software write protection - deployed in boot code storage for industrial microcontroller systems.
For engineers reviewing the S25FL132K0XNFV040 datasheet, S25FL132K0XNFV040 pinout, S25FL132K0XNFV040 application, or S25FL132K0XNFV040 equivalent, key selection considerations include quad-speed XIP capability, AEC-Q100 Grade 2 qualification, SFDP compliance, and migration path to S25FL064L for new designs.
Technical Context
This device implements a 90 nm floating-gate NOR architecture with SPI-MIO support for Single/Dual/Quad I/O protocols using only four to six pins (CS#, SCK, IO0–IO3). Its command set is backward-compatible with prior S25FL-K families but omits legacy commands like Quad Page Program (32h) and Half-Block Erase (52h).
It integrates volatile and non-volatile configuration registers, supports Execute-In-Place (XIP) via Continuous and Wrapped Read modes, and enables secure firmware storage through pointer-based block protection, OTP-locked security registers, and lock-down-until-power-cycle functionality.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 Mbyte) - sufficient for full MCU boot image plus firmware update partition |
| Interface | SPI Multi-I/O (SIO/DIO/QIO) - reduces pin count vs parallel NOR while maintaining XIP performance |
| Max Read Speed | 54 MB/s (Quad Read @ 108 MHz, –40°C to +105°C) - matches x16 parallel NOR bandwidth |
| Erase Granularity | Uniform 4 kB sectors and 64 kB blocks - enables fine-grained OTA update partitioning |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - meets industrial lifecycle requirements |
| Supply Voltage | 2.6 V to 3.6 V - compatible with 3.3 V logic rails and brown-out tolerant operation |
| Temperature Range | –40 °C to +105 °C (Industrial Plus) - qualified for under-hood and factory automation use |
Pinout & Package
Package: 8-contact USON (4 mm × 4 mm), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable for command decoding; must be held low during entire SPI transaction |
| SCK | Serial Clock | Input clock synchronizing all I/O transfers; supports up to 108 MHz for Quad Read |
| IO0 (SI) | Serial Input / Data Line 0 | Primary input for instructions, addresses, and program data in SIO/DIO/QIO modes |
| IO1 (SO) | Serial Output / Data Line 1 | Primary output for read data in SIO mode; bidirectional in DIO/QIO |
| IO2 (WP#) | Write Protect Input | Hardware-level protection override; disables program/erase when asserted low |
| IO3 (HOLD#) | Hold Input | Suspends ongoing command mid-execution without CS# deassertion; resumes on release |
| VCC | Power Supply | Single 2.6–3.6 V supply powering core and I/O; no separate VIO required |
| VSS | Ground | Common reference for all signals; requires low-inductance connection to minimize noise |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read (QIO) Mode | Enables 54 MB/s continuous throughput - eliminates bottleneck for XIP execution from flash |
| Program/Erase Suspend | Allows background read access during long erase operations - critical for real-time system responsiveness |
| Three 256-byte OTP Security Registers | Stores immutable keys, certificates, or calibration data - prevents field tampering of critical parameters |
| Pointer-Based Block Protection | Configurable 4 kB–full-memory protection range via status register bits - supports flexible firmware partitioning |
| SFDP Compliance (JESD216B) | Self-describing parameter table accessible via standard command - enables automatic driver initialization |
Applications

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 |
|---|---|---|---|
| S25FL064L0XNFB040 | 64 Mbit density; 133 MHz Quad Read; 1.8 V / 3.0 V dual supply; enhanced SFDP v1.6 | Supports larger firmware images and higher bandwidth XIP; requires voltage translation in pure 3.3 V systems | Select for new designs needing extended density, higher speed, or future-proof SFDP features |
| MX25L3233FZNI-10G | 32 Mbit; 104 MHz Quad Read; 2.7–3.6 V supply; no Industrial Plus temp grade | Lacks AEC-Q100 qualification and –40°C to +105°C rating; lower max clock rate limits XIP performance | Acceptable for commercial-temp applications where cost is prioritized over extended reliability |
Compared with S25FL132K0XNFV040, S25FL064L0XNFB040 offers higher density and speed for next-gen designs, while MX25L3233FZNI-10G provides cost-efficient drop-in replacement where extended temperature and automotive qualification are not required.

FAQ
Is S25FL132K0XNFV040 recommended for new designs?
No. Cypress explicitly designates this part as "Not Recommended for New Design" and recommends migrating to S25FL064L for all new projects. It remains available for legacy production and repair, with full technical support and lifecycle coordination through Aetrix Electronics.
What package does S25FL132K0XNFV040 use?
S25FL132K0XNFV040 uses an 8-contact USON package (4 mm × 4 mm, code UNF008), with wettable flanks for automated optical inspection and lead-free RoHS compliance. Pinout matches SOIC-8 footprints electrically but occupies 44% less board area.
Does it support Execute-In-Place (XIP) reliably?
Yes. With Continuous Read and Wrapped Read modes, plus 108 MHz Quad Read (54 MB/s), it delivers deterministic latency and bandwidth sufficient for direct code execution - validated in industrial MCU platforms including ARM Cortex-M7 and RISC-V SoCs with SPI memory controllers.
How is security implemented in this device?
Security includes three 256-byte OTP registers for immutable keys, 8-byte unique ID per unit, software/hardware write protection (WP# pin), lock-down-until-power-cycle mode, and pointer-based block protection covering 4 kB to full array - all controlled via non-volatile status register bits per JEDEC JESD216B SFDP.
