Product details
Overview
S25FL164K0XNFA011 from Cypress Semiconductor is a 64-Mbit (8 Mbyte), 3.0 V serial NOR flash memory with SPI Multi-I/O interface, supporting Quad Read at 108 MHz (54 MB/s) and Execute-In-Place (XIP) operation for embedded code storage. It features uniform 4-kB sector and 64-kB block erase, 100K program-erase cycles, 20-year data retention, and hardware/software write protection including OTP security registers. Used in industrial microcontroller boot code storage and firmware update storage.
For engineers reviewing the S25FL164K0XNFA011 datasheet, S25FL164K0XNFA011 pinout, S25FL164K0XNFA011 application, or S25FL164K0XNFA011 equivalent, key selection criteria include quad-mode read throughput, sector protection granularity, deep power-down current (2 µA), AEC-Q100 Grade 2 qualification, and migration path to S25FL064L.
Technical Context
This SPI flash implements JEDEC-standard Serial Flash Discoverable Parameters (SFDP) and supports SPI clock modes 0 and 3. Its 90 nm floating gate process enables stable operation across −40 °C to +105 °C (Industrial Plus) with single 2.7–3.6 V supply.
The device integrates three 256-byte one-time-programmable (OTP) security registers, pointer-based block protection, and 8-byte unique ID. Command set includes Program Suspend/Resume and Erase Suspend/Resume - features absent in legacy S25FL-P family but retained from S25FL-K.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 Mbyte) - sufficient for full MCU boot image + firmware partition in space-constrained designs |
| Read Throughput | 54 MB/s (Quad Read @ 108 MHz) - matches parallel NOR performance with 4-pin interface reduction |
| Erase Granularity | 4 kB sectors / 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 |

| VCC | Supply Voltage | 2.7–3.6 V single rail; supports brown-out detection and low-voltage program inhibit |
| VSS | Ground | Signal reference; decoupling capacitor required within 5 mm of VCC/VSS pins |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read Mode | Enables 54 MB/s continuous read - eliminates bottleneck for XIP execution in Cortex-M7/M4 applications |
| Program/Erase Suspend | Allows background erase to pause while servicing high-priority interrupts - essential for real-time OS environments |
| Pointer-Based Protection | Configurable 4 kB–full-memory protection range via status register bits - replaces fixed-sector locking |
| Variable Dummy Cycles | Adjustable latency for faster initial access or higher clock rate - improves boot time predictability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064L0XNFA010 | Successor part with 64 Mbit density, 133 MHz Quad Read (66.5 MB/s), 256 KB uniform sectors, and enhanced SFDP v1.6 compliance | Required for new designs; supports faster boot and larger firmware partitions; lacks legacy S25FL1-K command compatibility | Select for new designs needing higher performance and extended lifecycle support; requires firmware driver update |
| MX25L6433FZNI-10G | 64 Mbit SPI flash from Macronix; 104 MHz Quad Read (52 MB/s); no Program/Erase Suspend; 10-year data retention | Lower cost alternative where suspend/resume and 20-year retention are non-critical; no AEC-Q100 qualification | Acceptable for commercial-grade networking gear with shorter product lifecycles; verify hold timing margins in high-noise environments |
Compared with S25FL164K0XNFA011, S25FL064L offers higher throughput and longer manufacturer support but requires driver changes, while MX25L6433F provides cost savings at the expense of endurance, retention, and automotive qualification.

FAQ
Is S25FL164K0XNFA011 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. It remains available for legacy production and repair, with full technical documentation and known lifecycle behavior, but no future revisions or long-term supply guarantees.
What package does S25FL164K0XNFA011 use?
S25FL164K0XNFA011 uses an 8-contact WSON package measuring 5 mm × 6 mm (designated WND008), with exposed thermal pad, RoHS-compliant matte tin finish, and moisture sensitivity level 3. Pinout matches industry-standard SOIC-8 and USON-8 footprints for layout reuse.
Does this device support Execute-In-Place (XIP) reliably?
Yes - S25FL164K0XNFA011 supports efficient XIP via Continuous Read and Wrapped Read modes, with ≤8-clock overhead per access and 54 MB/s Quad Read bandwidth. Its 108 MHz clock rate and low-latency dummy cycle configuration ensure deterministic instruction fetch timing for Cortex-M and RISC-V cores.
How is security implemented in this flash memory?
Security includes three 256-byte OTP registers (locked permanently after programming), top/bottom block protection with pointer-based range control, 8-byte unique device ID, and dual-layer write protection (hardware WP# pin + software status register bits). All features are validated per datasheet electrical and functional specs.
