Product details
Overview
S25FL164K0XNFA013 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, and 20-year data retention. Used for XIP code execution and firmware storage in space-constrained embedded controllers.
For engineers reviewing the S25FL164K0XNFA013 datasheet, S25FL164K0XNFA013 pinout, S25FL164K0XNFA013 application, or S25FL164K0XNFA013 equivalent, key selection factors include Quad I/O read performance, industrial-plus temperature support (−40 °C to +105 °C), hardware/software write protection, security register OTP, and migration path to S25FL064L.
Technical Context
This device implements JEDEC-standard SPI with configurable clock polarity/phase (modes 0 and 3), supports Serial Flash Discoverable Parameters (SFDP) for automatic configuration, and enables Execute-In-Place (XIP) via Continuous and Wrapped Read modes. Its 90 nm floating gate process ensures stable operation across voltage (2.6–3.6 V) and extended temperature ranges.
The memory integrates three 256-byte one-time-programmable (OTP) security registers, pointer-based block protection, and dual protection mechanisms-hardware (WP#/HOLD# pins) and software command lock-down. Quad I/O mode disables WP#/HOLD# functionality, enforcing protocol-exclusive signal routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 Mbyte) - sufficient for full firmware images and parameter tables in mid-tier microcontrollers |
| Interface | SPI Multi-I/O (SIO/DIO/QIO) - reduces pin count vs parallel NOR while maintaining XIP-capable bandwidth |
| Max Read Speed | 108 MHz Quad Read - enables 54 MB/s throughput, matching x16 asynchronous NOR in cache-line fill scenarios |
| Erase Granularity | 4 kB sectors / 64 kB blocks - balances update flexibility and wear leveling for OTA firmware partitions |
| Endurance & Retention | 100K cycles / 20 years - validated for industrial control logging and infrequent field-upgrade applications |
| Supply Voltage | 2.6 V to 3.6 V - compatible with 3.3 V logic rails and brown-out tolerant in battery-backed systems |
| Temperature Range | −40 °C to +105 °C (Industrial Plus) - qualified for under-hood automotive ECUs and industrial motor drives |
Pinout & Package
Package: 8-lead SOIC (208 mil), standardized footprint per SOC008 specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable for command initiation; must be held low for entire instruction sequence |
| SCK | Serial Clock | Input clock synchronizing all SPI transfers; supports up to 108 MHz in Quad mode |
| IO0 (SI) | Serial Input / Data Line 0 | Primary data input in SIO/DIO/QIO; bidirectional in DIO/QIO after command phase |
| IO1 (SO) | Serial Output / Data Line 1 | Primary data output in SIO; bidirectional in DIO/QIO; used for Dual/Quad read payloads |
| IO2 (WP#) | Write Protect Input | Hardware-level protection override; disabled when Quad I/O mode is active |
| IO3 (HOLD#) | Command Hold Input | Suspends ongoing read/program/erase; disabled in Quad I/O mode |
| VCC | Power Supply | Single 2.6–3.6 V supply; powers core and I/O circuits; decoupling required near pin |
| VSS | Ground | Signal and power reference; requires low-impedance connection to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read with 54 MB/s throughput | Enables real-time XIP from flash without external RAM buffering in resource-limited MCUs |
| Program/Erase suspend-resume | Allows background firmware updates without interrupting real-time control loops or communication stacks |
| Three 256-byte OTP security registers | Stores cryptographic keys or calibration data that survives reprogramming of main array |
| Pointer-based block protection | Configurable 4 kB–full-memory write lock range via status register, independent of physical sector layout |
| Wrapped Read mode | Optimizes cache-line refill by reading miss-triggering byte first, then contiguous burst - cuts latency by ~30% vs standard read |
Applications
| Industrial PLC Firmware Storage | Automotive ECU Boot Code |
|---|---|
Use Scenario: Storing ladder logic programs and I/O mapping tables in modular programmable logic controllers requiring field updates via SD card or Ethernet. IC Role / Device Role / Timing Role: Non-volatile boot and application code storage with XIP capability; timing-critical during cold start and firmware validation. Use Value: 4 kB sector erase enables atomic firmware patching; 105 °C rating ensures reliability in cabinet-mounted enclosures near heat-generating drives. | Use Scenario: Holding ASAM-compliant boot loader and safety-critical calibration data in engine control units subject to AEC-Q100 Grade 2 qualification. IC Role / Device Role / Timing Role: Primary boot memory accessed during power-on reset; supports secure read-after-write verification before handing off to MCU core. Use Value: OTP security registers store asymmetric keys for UDS authentication; hardware WP# prevents accidental corruption during CAN FD firmware download. |
| Medical Diagnostic Imaging UI | Smart Energy Meter Firmware |
Use Scenario: Hosting GUI assets, image processing microcode, and regulatory compliance logs in portable ultrasound devices with strict EMC and thermal constraints. IC Role / Device Role / Timing Role: High-bandwidth read source for display frame buffers; operates in Continuous Read mode to sustain 60 Hz UI refresh. Use Value: 54 MB/s Quad Read eliminates need for external SDRAM; 8-contact WSON package (WND008) fits tight 4-layer PCB layouts. | Use Scenario: Storing DLMS/COSEM protocol stacks, tariff tables, and tamper-event history in ANSI C12.22-compliant smart meters deployed in outdoor substations. IC Role / Device Role / Timing Role: Long-term firmware archive with periodic over-the-air updates; retains data through 15+ year service life. Use Value: 20-year data retention and 100K endurance meet ANSI C12.19 lifecycle requirements; sector protection isolates utility-signed firmware from user-modifiable parameters. |
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 |
|---|---|---|---|
| S25FL064L0XNFA013 | Successor family; 64 Mbit, 133 MHz Quad Read, 256-byte page, 133K endurance, 25-year retention | Supports higher clock rates and longer lifecycle; includes enhanced SFDP v1.6 and octal-compatible pinout | Select for new designs requiring extended longevity, higher bandwidth, or future-proofing against obsolescence |
| MX25L6433FZNI-10G | 64 Mbit, 104 MHz Quad Read, 2.7–3.6 V, 100K endurance, no OTP security registers | Lacks pointer-based protection and dedicated security registers; uses standard status register locking only | Choose where cost sensitivity outweighs security requirements and legacy design reuse is prioritized |
Compared with S25FL164K0XNFA013, S25FL064L0XNFA013 delivers measurable gains in read speed and endurance while maintaining pin compatibility, whereas MX25L6433FZNI-10G offers lower cost but omits critical security features needed for certified firmware integrity.

FAQ
Is S25FL164K0XNFA013 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and recommends migrating to the S25FL064L family. It remains available for legacy production and repair, with full technical support and traceable sourcing through Aetrix Electronics' lifecycle management program.
What package does S25FL164K0XNFA013 use?
S25FL164K0XNFA013 uses an 8-lead SOIC package with 208 mil body width (SOC008). This is distinct from the 150 mil SOA008 variant used in lower-density variants and confirms mechanical compatibility with standard 208-mil SOIC footprints on industrial PCBs.
Does it support Quad I/O mode with hardware write protection active?
No. When Quad I/O mode is enabled, the WP# and HOLD# pins are repurposed as IO2 and IO3, disabling hardware write protection and hold functionality. Protection must be implemented via software commands (e.g., Write Enable + Write Status Register) in QIO configurations.
Can it be used in automotive applications requiring AEC-Q100 qualification?
Yes - the S25FL164K0XNFA013 is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C) and Grade 3 (−40 °C to +85 °C). Full qualification documentation, including HTOL and TC testing reports, is available upon request for automotive Tier 1 design-in support.
