Product details
Overview
S25FL164K0XNFV010 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 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. Used in embedded boot code storage and firmware update storage for industrial controllers.
For engineers reviewing the S25FL164K0XNFV010 datasheet, S25FL164K0XNFV010 pinout, S25FL164K0XNFV010 application, or S25FL164K0XNFV010 equivalent, key selection considerations include Quad I/O timing compliance, security register OTP configuration, AEC-Q100 Grade 2 temperature support (–40°C to +105°C), and migration path to S25FL064L.
Technical Context
The S25FL164K0XNFV010 implements JEDEC-standard SPI command set with modes 0 and 3 clock polarity/phase support, enabling interoperability with legacy and modern host controllers. Its Serial Flash Discoverable Parameters (SFDP) table (JEDEC JESD216B) provides programmable read latency and configuration registers accessible via standard commands.
It integrates three 256-byte one-time-programmable (OTP) security registers, pointer-based block protection, and dual hardware protection inputs (WP# and HOLD#), with Quad I/O mode disabling WP#/HOLD# functionality. The 90 nm floating gate process enables stable operation across Industrial Plus (–40°C to +105°C) and AEC-Q100 Grade 2 automotive ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 Mbyte) - supports full firmware images for mid-complexity microcontrollers without external memory expansion. |
| Interface | SPI Multi-I/O (SIO/DIO/QIO) - reduces pin count vs parallel NOR; QIO mode delivers 54 MB/s, matching x16 asynchronous NOR bandwidth. |
| Max Clock Rate | 108 MHz (Quad Read) - enables sub-100 ns effective access latency in wrapped/continuous read modes for XIP efficiency. |
| Erase Granularity | 4 kB sectors / 64 kB blocks - allows fine-grained firmware patching and robust field updates without full chip erase. |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - validated for industrial control logging and automotive ECU calibration storage. |
| Supply Voltage | 2.7 V to 3.6 V - compatible with 3.3 V logic rails; low supply voltage protection prevents inadvertent writes during brown-out. |
| Temperature Range | –40°C to +105°C (Industrial Plus) - qualified per AEC-Q100 Grade 2, suitable for under-hood automotive modules. |
Pinout & Package
Package: 24-ball BGA (6 mm × 8 mm, FAB024/FAC024 footprint). Lead-free, RoHS-compliant, 0.8 mm ball pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable for command decoding; must be asserted for all SPI transactions including status polling. |
| SCK | Serial Clock | Input clock synchronized to host controller; supports up to 108 MHz in Quad Read mode with defined setup/hold timing. |
| IO0 (SI) | Serial Input / Data Line 0 | Primary input for instructions, addresses, and program data in SIO/DIO/QIO modes; bidirectional in QIO. |
| IO1 (SO) | Serial Output / Data Line 1 | Primary output for read data in SIO; bidirectional in DIO/QIO; used for dual/quad data transfer. |
| IO2 (WP#) | Write Protect Input | Hardware lock for top/bottom memory blocks; active-low; disabled when Quad I/O mode is enabled. |
| IO3 (HOLD#) | Hold Input | Suspends ongoing command (read/program/erase) mid-execution; resumes on deassertion; disabled in QIO mode. |
| VCC | Core & I/O Supply | Single 2.7–3.6 V rail powers logic and I/O buffers; internal regulation ensures stable core voltage across range. |
| VSS | Ground | Dedicated signal ground; separate from power ground in layout-critical applications to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Execute-In-Place (XIP) Optimization | Continuous and wrapped read modes reduce instruction fetch overhead to ≤8 clocks per access, enabling real-time deterministic code execution from flash. |
| Security Register Architecture | Three 256-byte OTP regions support secure boot keys, device-specific certificates, and SFDP parameter customization-locked permanently after programming. |
| Flexible Protection Scheme | Top/bottom block protection with 4 kB granularity, software command lock, hardware WP# input, and lock-down-until-power-cycle mode prevent unauthorized firmware modification. |
| Migration-Compatible Footprint | Pinout and command set match prior S25FL-K families, allowing drop-in replacement in existing SOIC/WSON/BGA layouts without PCB revision. |
| Volatile Configuration Option | Non-volatile status register bits can be overridden by volatile configuration register, enabling dynamic protection reconfiguration without permanent register writes. |
Applications
| Industrial PLC Firmware Storage | Automotive ADAS Boot Memory |

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 |
|---|---|---|---|
| S25FL064L0XNFB010 | Successor device; same 64 Mbit density, 108 MHz Quad Read, but built on 65 nm process with lower active current (12 mA vs 16 mA @ Quad Read) and extended -40°C to +125°C option. | Supports higher ambient temperature environments (e.g., base station RF modules); includes enhanced SFDP v1.6 and configurable reset vector. | Select for new designs requiring longer lifecycle support, lower power, or extended temperature qualification beyond +105°C. |
| MX25L6433FZNI-10G | 64 Mbit SPI NOR from Macronix; 133 MHz max clock, 66 MB/s Quad Read, but lacks OTP security registers and AEC-Q100 qualification. | Cost-optimized for consumer IoT gateways; no hardware block protection or automotive temperature validation. | Acceptable for cost-sensitive, non-safety-critical applications where security and automotive qualification are not required. |
Compared with S25FL164K0XNFV010, S25FL064L0XNFB010 offers improved power efficiency and broader temperature support for future-proofing, while MX25L6433FZNI-10G trades security and qualification for lower unit cost in commercial-grade systems.

FAQ
Is S25FL164K0XNFV010 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. While fully functional and supported for existing production, new projects should adopt S25FL064L for long-term supply assurance, improved power efficiency, and extended temperature options up to +125°C.
What package does S25FL164K0XNFV010 use, and is it RoHS-compliant?
S25FL164K0XNFV010 uses a 24-ball BGA package (6 mm × 8 mm, FAB024/FAC024 footprint) with 0.8 mm ball pitch. It is lead-free and RoHS-compliant per Cypress documentation, with NiPdAu surface finish and JEDEC-standard moisture sensitivity level (MSL) 3 handling requirements.
Does this device support Execute-In-Place (XIP) directly from flash?
Yes. The S25FL164K0XNFV010 supports efficient XIP via Continuous Read Mode (≤8-clock overhead per access) and Wrapped Read Mode (cache-line fill with single command), both optimized for deterministic instruction fetch at up to 108 MHz Quad Read speed-enabling real-time code execution without RAM shadowing.
How is security implemented, and can the OTP registers be reprogrammed?
Security relies on three 256-byte OTP registers (768 bytes total), each permanently locked after first programming. Additional protections include top/bottom block protection with 4 kB granularity, software command lock, hardware WP# input, and lock-down-until-power-cycle mode. Once programmed, OTP content cannot be altered or erased.
