Product details
Overview
S25FL132K0XNFV011 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 S25FL132K0XNFV011 datasheet, S25FL132K0XNFV011 pinout, S25FL132K0XNFV011 application, or S25FL132K0XNFV011 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 a JEDEC-standard SPI interface with configurable clock polarity/phase (modes 0 and 3), supporting Normal, Fast, Dual, and Quad Read commands. Its internal architecture uses 90 nm floating gate technology and includes dedicated XIP-optimized continuous/wrapped read modes with variable dummy cycles for latency tuning.
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 - enabling secure firmware storage in automotive Grade 2 (−40 °C to +105 °C) and industrial plus environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (4 Mbyte) - sufficient for full bootloader + application image in space-constrained MCU systems |
| Read Throughput | 54 MB/s (Quad Read @ 108 MHz) - matches parallel NOR performance with only 6 pins |
| Erase Granularity | 4 kB sectors / 64 kB blocks - enables fine-grained firmware partitioning and OTA update safety |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - validated for long-life industrial deployments |
| 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 automotive and high-ambient industrial use |
| Security Features | Three 256-byte OTP registers + 8-byte unique ID - supports secure boot key binding and device identity |
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 SPI command sequence; must be deasserted between commands |
| SCK | Serial Clock | Input clock driving all SPI transfers; supports up to 108 MHz for Quad Read |
| IO0 (SI) | Serial Input / Data Line 0 | Primary data input in SIO mode; bidirectional in DIO/QIO; used for instruction/address/data |
| IO1 (SO) | Serial Output / Data Line 1 | Primary data output in SIO mode; bidirectional in DIO/QIO; supports dual/quad read burst |
| IO2 (WP#) | Write Protect Input | Hardware-level protection override; disables program/erase when asserted low |
| IO3 (HOLD#) | Command Hold Input | Suspends ongoing command (e.g., erase) without losing state; resumes on deassertion |
| VCC | Power Supply | Single 2.6–3.6 V supply; powers core and I/O circuits; no separate VIO required |
| VSS | Ground | Common reference for all signals; requires low-impedance connection to minimize noise |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read (QIO) Mode | Enables 54 MB/s throughput using all four I/O lines - eliminates need for wider parallel interfaces |
| Program/Erase Suspend | Allows interrupting long erase operations to service time-critical reads - critical for real-time firmware updates |
| Continuous & Wrapped Read | Reduces XIP cache miss penalty to ≤8 clocks per access - improves deterministic code execution latency |
| Pointer-Based Block Protection | Configurable top/bottom protection range (4 kB to full array) - prevents accidental overwrite of critical firmware sections |
| JEDEC SFDP Support | Self-describing parameter table accessible via standard command - enables automatic driver configuration in Linux/Bare Metal |

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 |
|---|---|---|---|
| S25FL064L0XNFB010 | 64 Mbit density; 133 MHz Quad Read; 1.8 V / 3.0 V dual supply; enhanced SFDP v1.6 | Supports larger firmware images and newer drivers requiring v1.6 SFDP; backward-compatible pinout | Select for new designs requiring higher density, faster clock, or future-proof SFDP compliance |
| MX25L3233FZNI-10G | 32 Mbit; 104 MHz Quad Read; no OTP security registers; standard JEDEC ID only | Lacks pointer-based protection and unique ID; suitable for cost-sensitive, non-secure applications | Select where security features are unnecessary and BOM cost reduction is prioritized over long-term firmware integrity |
Compared with S25FL064L0XNFB010, the S25FL132K0XNFV011 offers proven industrial-plus reliability but lacks SFDP v1.6 and dual-voltage support; versus MX25L3233FZNI-10G, it delivers superior security and temperature robustness at higher unit cost.

FAQ
Is S25FL132K0XNFV011 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 enhanced density, speed, SFDP compliance, and long-term supply assurance.
What package does S25FL132K0XNFV011 use?
S25FL132K0XNFV011 uses an 8-contact USON package (4 mm × 4 mm), designated UNF008 in Cypress documentation. It is lead-free, RoHS-compliant, and rated at moisture sensitivity level 3 - requiring bake prior to reflow if exposed beyond floor life.
Does this device support Execute-In-Place (XIP)?
Yes - S25FL132K0XNFV011 supports efficient XIP via Continuous Read and Wrapped Read modes, with ≤8-clock overhead per access. Quad Read at 108 MHz achieves 54 MB/s, enabling direct code execution that rivals parallel NOR performance while reducing PCB routing complexity.
How is security implemented in S25FL132K0XNFV011?
Security is implemented via three 256-byte OTP security registers, 8-byte unique device ID, top/bottom block protection with pointer-based range control, and multiple protection layers: software command lock, hardware WP#/HOLD# inputs, and lock-down until power cycle - all configurable via status register bits.
