Product details
Overview
S25FL164K0XMFI001 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 control and automotive infotainment systems.
For engineers reviewing the S25FL164K0XMFI001 datasheet, S25FL164K0XMFI001 pinout, S25FL164K0XMFI001 application, or S25FL164K0XMFI001 equivalent, key selection criteria include quad-mode read throughput, 100K program-erase endurance, 20-year data retention, hardware/software write protection, and AEC-Q100 Grade 2 qualification for extended temperature operation.
Technical Context
This SPI flash implements JEDEC-standard Serial Flash Discoverable Parameters (SFDP) for automatic configuration and supports four I/O modes: Single, Fast, Dual, and Quad Read - all operating up to 108 MHz across −40 °C to +105 °C. It uses 90 nm floating gate technology and features volatile/non-volatile configuration registers.
The device integrates three 256-byte one-time-programmable (OTP) security registers, 8-byte unique ID, pointer-based block protection, and lock-down-until-power-cycle functionality. Erase suspend/resume and program suspend/resume enable real-time host interrupt handling during non-volatile operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 Mbyte) - sufficient for boot code, firmware images, and parameter tables in resource-constrained microcontrollers. |
| Read Throughput | 54 MB/s (Quad Read @ 108 MHz) - enables near-parallel-NOR performance with only 6 pins, reducing PCB routing complexity. |
| Erase Granularity | Uniform 4 kB sectors and 64 kB blocks - allows fine-grained firmware updates without disturbing adjacent functional sections. |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - meets long-life requirements for industrial and automotive deployments. |
| Supply Voltage | 2.6 V to 3.6 V - compatible with 3.3 V logic rails and tolerant of brown-out conditions down to 2.6 V. |
| Temperature Range | −40 °C to +105 °C (Industrial Plus) - qualified per AEC-Q100 Grade 2 for under-hood automotive applications. |
| Security Features | Three OTP security registers, 8-byte UID, software/hardware write protect, and lock-down mode - supports secure boot and IP protection. |
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 Input | Active-low enable for command initiation; must be held low for entire command sequence including address and data phases. |

| IO2 (WP#) | Write Protect Input / I/O | Hardware-level write protection; active-low; disabled when Quad I/O mode is enabled; supports permanent lock-down via OTP. |
| IO3 (HOLD#) | Hold Input / I/O | Suspends ongoing command (read/program/erase) mid-execution; resumes on deassertion; disabled in Quad I/O mode. |
| VCC | Power Supply | Single 2.6–3.6 V supply; powers core logic and I/O buffers; decoupling capacitor required per datasheet layout guidelines. |
| VSS | Ground | Signal and power ground reference; requires low-inductance connection to PCB ground plane for signal integrity. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read Mode | Enables 54 MB/s continuous read throughput using all four I/O lines, eliminating need for parallel NOR in space-constrained XIP designs. |
| Program/Erase Suspend | Allows host CPU to interrupt active programming or erasing to service higher-priority tasks, then resume without data loss or timing penalty. |
| Pointer-Based Block Protection | Configurable protection range (4 kB to full array) via status register bits, enabling dynamic firmware partitioning without hardware redesign. |
| JEDEC SFDP Compliance | Self-describing parameter table accessible via standard command (5Ah), enabling automatic driver initialization and vendor-agnostic firmware support. |
| AEC-Q100 Grade 2 Qualification | Validated for −40 °C to +105 °C operation with HTOL, TC, and ESD testing - suitable for engine control units and ADAS domain controllers. |

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 |
|---|---|---|---|
| S25FL064L0XMFI001 | Successor device; same 64-Mbit density but 65 nm process, 133 MHz Quad Read (66.5 MB/s), enhanced SFDP v1.6, and improved deep power-down (0.9 µA). | Supports newer MCU drivers requiring SFDP v1.6; better suited for next-gen designs targeting lower power and higher bandwidth. | Select for new designs requiring extended lifecycle support and higher performance; not drop-in due to minor timing and command set differences. |
| MX25L6433FZNI-10G | 64-Mbit SPI NOR from Macronix; 104 MHz Quad Read (52 MB/s), 100K endurance, 20-year retention, but lacks AEC-Q100 qualification and pointer-based protection. | Cost-optimized alternative for commercial-grade applications where automotive qualification and advanced security are not required. | Choose for cost-sensitive industrial or consumer applications where AEC-Q100 and OTP-based security are not mandatory. |
Compared with S25FL064L0XMFI001, this part offers legacy compatibility and proven field reliability but lower bandwidth and no SFDP v1.6; versus MX25L6433FZNI-10G, it provides automotive qualification and stronger security at higher cost and slightly lower speed.

FAQ
Is S25FL164K0XMFI001 recommended for new designs?
No - Cypress explicitly states this part is "Not Recommended for New Design" and recommends migration to S25FL064L. However, Aetrix Electronics maintains active inventory and supply chain support for legacy design refresh, repair, and maintenance programs requiring exact form-fit-function replacement.
What package does S25FL164K0XMFI001 use?
S25FL164K0XMFI001 uses an 8-lead SOIC package with 208-mil width (standard JEDEC MS-012AC, footprint code SOC008), measuring 5.3 mm × 5.3 mm with 1.27 mm lead pitch. It is not pin-compatible with 16-lead SOIC variants in the same family.
Does this device support Execute-In-Place (XIP)?
Yes - S25FL164K0XMFI001 supports efficient XIP via Continuous Read Mode and Wrapped Read Mode, enabling direct instruction fetch by host MCUs. Quad Read at 108 MHz achieves 54 MB/s throughput, matching or exceeding legacy parallel NOR performance with reduced pin count.
How is write protection implemented?
Write protection is implemented through three independent mechanisms: hardware WP# pin (active-low), software commands (WRDI, WRSR), and OTP-configurable block protection ranges. The pointer-based protection allows dynamic definition of protected memory regions from 4 kB up to full array size.
