Product details
Overview
S25FL164K0XNFA010 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 100K program-erase cycles - deployed in embedded boot code storage for industrial microcontroller systems.
For engineers reviewing the S25FL164K0XNFA010 datasheet, S25FL164K0XNFA010 pinout, S25FL164K0XNFA010 application, or S25FL164K0XNFA010 equivalent, key selection criteria include quad I/O read bandwidth, OTP security register support, AEC-Q100 Grade 2 qualification, and migration path to S25FL064L for new designs.
Technical Context
This device implements JEDEC-standard SPI command set with configurable clock polarity/phase (modes 0 and 3), supports Execute-In-Place (XIP) via Continuous and Wrapped Read modes, and includes Serial Flash Discoverable Parameters (SFDP) for automatic configuration discovery by host controllers.
It integrates three 256-byte one-time-programmable (OTP) security registers, pointer-based block protection, and hardware/software write protection using WP# and status register bits - enabling secure firmware storage in automotive and industrial applications requiring tamper-resistant boot code.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 Mbyte) - sufficient for full MCU boot image + configuration data in space-constrained designs |
| Interface | SPI Multi-I/O (x1/x2/x4) - reduces pin count vs parallel NOR while maintaining XIP performance |
| Max Read Speed | 108 MHz Quad Read (54 MB/s) - matches or exceeds legacy x8/x16 parallel NOR bandwidth |
| Erase Granularity | Uniform 4 kB sectors and 64 kB blocks - enables fine-grained firmware update without full chip erase |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - meets long-life requirements for industrial control firmware |
| Supply Voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and brown-out tolerant operation |
| Temperature Range | AEC-Q100 Grade 2 (–40°C to +105°C) - qualified for under-hood automotive and high-temp industrial use |
Pinout & Package
Package: 8-lead SOIC (208 mil), surface-mount, RoHS-compliant, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable for SPI command sequence; must be asserted before SCK edge to initiate communication |
| SCK | Serial Clock | Input clock synchronizing all SPI transfers; supports up to 108 MHz for Quad Read operations |
| IO0 (SI) | Serial Input / Data Line 0 | Primary data input during programming; bidirectional in Dual/Quad mode for data transfer |
| IO1 (SO) | Serial Output / Data Line 1 | Primary data output during read; bidirectional in Dual/Quad mode for high-speed streaming |
| IO2 (WP#) | Write Protect Input | Hardware-level protection override; disables program/erase when pulled low, independent of status register |
| IO3 (HOLD#) | Hold Input | Suspends ongoing command mid-execution (e.g., during erase) without losing internal state |
| VCC | Power Supply | Single 2.7–3.6 V supply powering core and I/O; no separate VIO required |
| VSS | Ground | Common reference for all signals; requires low-impedance connection to minimize noise in high-speed reads |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read (QIO) Mode | Enables 54 MB/s continuous read throughput - eliminates need for external RAM buffering in XIP applications |
| Program/Erase Suspend | Allows interrupting long erase cycles (e.g., 500 ms block erase) to service real-time host requests |
| Three 256-byte OTP Registers | Stores immutable keys, calibration data, or device-specific identifiers - protected against accidental overwrite |
| Pointer-Based Block Protection | Configurable 4 kB–full-memory protection range via software commands - supports hierarchical firmware partitioning |
| JEDEC SFDP Support | Self-describing parameter table enables automatic host controller configuration without hard-coded timing values |
Applications
| Industrial PLC Firmware Storage | Automotive ADAS Boot Memory |
|---|---|

Use Value: Reduces annual battery drain by >95% vs standard SPI flash, extending meter battery life beyond 15 years. |
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 |
|---|---|---|---|
| S25FL064L0XNFA010 | Successor device with 65 nm process, 133 MHz Quad Read (66.5 MB/s), enhanced SFDP v1.6, and extended 200K endurance | Supports higher-performance XIP in next-gen MCUs; adds dual-die stack option for density scaling | Select for new designs requiring longer product lifecycle, higher speed, and Cypress's current-generation roadmap support |
| MX25L6433FZNI-10G | 64 Mbit Macronix device with 104 MHz Quad Read (52 MB/s), no OTP registers, and only 10K endurance rating | Lacks security features and automotive qualification; suited for cost-sensitive consumer applications | Consider only if security, endurance, or AEC-Q100 compliance are not required and legacy footprint compatibility is critical |
Compared with S25FL164K0XNFA010, S25FL064L0XNFA010 delivers higher bandwidth and longevity for future-proof designs, while MX25L6433FZNI-10G offers lower cost but sacrifices security, endurance, and automotive qualification - making it unsuitable for safety-critical or long-life deployments.
