Product details
Overview
S25FL164K0XMFV001 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), uniform 4-kB sector and 64-kB block erase, and Execute-In-Place (XIP) operation for embedded code storage in industrial and automotive systems.
For engineers reviewing the S25FL164K0XMFV001 datasheet, S25FL164K0XMFV001 pinout, S25FL164K0XMFV001 application, or S25FL164K0XMFV001 equivalent, key selection criteria include quad-speed read performance, OTP security register support, AEC-Q100 Grade 2 qualification (–40°C to +105°C), and migration path to S25FL064L.
Technical Context
This SPI flash implements JEDEC-standard Serial Flash Discoverable Parameters (SFDP) for automatic configuration, supports SPI clock modes 0 and 3, and enables hardware write protection via WP# and suspend/resume for program/erase operations. Its 90 nm floating gate process ensures 100K program-erase cycles and 20-year data retention.
The device features three 256-byte one-time-programmable (OTP) security registers, pointer-based block protection, and an 8-byte unique ID. It operates across Industrial Plus (–40°C to +105°C) and AEC-Q100 Grade 2 temperature ranges with supply voltage from 2.6 V to 3.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 Mbyte) - sufficient for boot code, firmware images, and parameter storage in resource-constrained microcontrollers. |
| Interface | SPI Multi-I/O (x1/x2/x4) - reduces pin count vs parallel NOR while enabling 54 MB/s quad read throughput. |
| Max Clock Rate | 108 MHz - enables high-speed XIP execution and fast firmware updates without bus bottlenecks. |
| Erase Granularity | Uniform 4 kB sectors and 64 kB blocks - allows fine-grained firmware patching and robust field upgrade partitioning. |
| Data Retention | 20 years minimum - guarantees long-term reliability in unattended industrial and automotive deployments. |
| Endurance | 100,000 program-erase cycles - supports frequent over-the-air (OTA) firmware updates over product lifetime. |
| Supply Voltage | 2.6 V to 3.6 V - compatible with modern low-voltage SoCs and battery-backed systems. |
| Temperature Range | AEC-Q100 Grade 2 (–40°C to +105°C) - qualified for under-hood automotive ECUs and industrial edge controllers. |
Pinout & Package
Package: 8-lead SOIC (208 mil), body size 5.3 mm × 5.3 mm, standard JEDEC MS-012AC footprint (SOC008).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable for SPI command initiation; must be held low for entire command sequence. |
| SCK | Serial Clock | Input clock synchronizing all SPI transfers; supports up to 108 MHz for quad read mode. |
| IO0 (SI) | Serial Input / Data I/O 0 | Primary data input in single/dual/quad mode; functions as SI in legacy SPI, IO0 in DIO/QIO. |
| IO1 (SO) | Serial Output / Data I/O 1 | Primary data output in single mode; becomes bidirectional IO1 in dual/quad mode. |
| IO2 (WP#) | Write Protect / Data I/O 2 | Hardware write lock for top/bottom memory regions; disabled when QIO mode is active. |
| IO3 (HOLD#) | Hold / Data I/O 3 | Suspends ongoing command mid-execution; resumes on next SCK edge; disabled in QIO mode. |
| VCC | Power Supply | Single 2.6–3.6 V supply powering core logic and I/O drivers; no separate VIO required. |
| VSS | Ground | Common reference for all signals; requires low-impedance connection to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read (QIO) Mode | 54 MB/s sustained throughput enables real-time XIP of complex firmware without external RAM buffering. |
| Program/Erase Suspend | Allows background erase to pause and service high-priority read requests-critical for deterministic real-time response. |
| Three 256-byte OTP Registers | Stores immutable keys, calibration data, or device identity; prevents tampering after initial programming. |
| Pointer-Based Block Protection | Enables dynamic, software-defined memory lock ranges-supports secure OTA update staging and rollback. |
| SFDP (JESD216B) | Self-describing configuration eliminates hard-coded timing parameters; simplifies driver portability across flash families. |
| AEC-Q100 Grade 2 Qualification | Validated for automotive under-hood environments including thermal cycling, vibration, and ESD robustness. |
Applications
| Automotive Engine Control Unit (ECU) | Industrial PLC Firmware Storage |
|---|---|

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 |
|---|---|---|---|
| S25FL064L0XMFI001 | Successor part with 64 Mbit density, 133 MHz Quad Read (66.5 MB/s), 65 nm process, and extended 2.3–3.6 V supply range. | Supports newer MCU platforms with higher SPI clock tolerance; lacks legacy S25FL1-K command subset compatibility. | Select for new designs requiring higher speed, lower voltage, and longer product availability. |
| MX25L6433FZNI-10G | 64 Mbit SPI NOR with 104 MHz Quad Read (52 MB/s), 1.65–3.6 V supply, and no AEC-Q100 qualification. | Cost-optimized alternative for commercial-grade applications; no automotive temperature or qualification support. | Select only for non-automotive, non-industrial-plus environments where qualification is not required. |
Compared with S25FL164K0XMFV001, S25FL064L offers higher performance and broader voltage range but requires firmware driver updates, while MX25L6433F provides cost savings at the expense of automotive qualification and endurance margin.

FAQ
Is S25FL164K0XMFV001 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and recommends migrating to S25FL064L. It remains available for legacy production and repair, with full technical documentation and known lifecycle status. Aetrix maintains inventory and supports obsolescence management for ongoing builds.
What package does S25FL164K0XMFV001 use?
S25FL164K0XMFV001 uses an 8-lead SOIC (208 mil) package per JEDEC MS-012AC, designated SOC008. Pinout matches standard SPI NOR flash: CS#, SCK, IO0, IO1, IO2 (WP#), IO3 (HOLD#), VCC, and VSS. No NC or RFU pins are present in this variant.
Does it support Quad SPI mode with hardware write protection enabled?
No. When Quad I/O (QIO) mode is activated, the WP# and HOLD# functions are disabled per the datasheet. Hardware write protection is only available in Single I/O and Dual I/O modes. Software-controlled protection (via Status Register bits) remains active in all modes.
How is security implemented in this device?
Security includes three 256-byte OTP registers, 8-byte unique ID, top/bottom block protection with pointer-based range definition, and lock-down-until-power-cycle mode. All protection modes are controlled via non-volatile status register bits and supported by hardware inputs (WP#, HOLD#) in non-QIO modes.
