Product details

Overview

S25FL164K0XNFI010 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 industrial embedded systems.

For engineers reviewing the S25FL164K0XNFI010 datasheet, S25FL164K0XNFI010 pinout, S25FL164K0XNFI010 application, or S25FL164K0XNFI010 equivalent, key selection criteria include Quad I/O timing compliance, security register OTP protection, Industrial Plus (−40 °C to +105 °C) temperature rating, and migration path to S25FL064L.

Technical Context

This device implements JEDEC-standard SPI Multi-I/O (MIO) with configurable clock polarity/phase (modes 0 and 3), supporting Single, Dual, and Quad I/O protocols using shared IO0–IO3 pins. Command execution includes suspend/resume for both program and erase operations, enabling real-time host control during background memory operations.

It integrates three 256-byte one-time-programmable (OTP) security registers, pointer-based block protection, and an 8-byte unique device ID. The memory array uses 90 nm floating gate technology and operates across 2.6 V–3.6 V supply with hardware write protect (WP#) and hold (HOLD#) inputs active in non-Quad modes.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (8 Mbyte) - supports full firmware images for mid-tier microcontrollers without external memory expansion.
Read Throughput	54 MB/s (Quad Read @ 108 MHz) - enables efficient execute-in-place (XIP) with cache-line-aligned wrapped reads.
Erase Granularity	4 kB sectors / 64 kB blocks - allows fine-grained firmware update partitioning while minimizing wear on critical boot sectors.
Endurance	100K program-erase cycles - sufficient for field firmware updates over 10+ years in industrial control applications.
Data Retention	20 years minimum at +85 °C - ensures long-term reliability in unattended equipment without refresh mechanisms.
Operating Voltage	2.6 V–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 for under-hood automotive ECUs and high-ambient industrial gateways.

Pinout & Package

Package: 8-lead SOIC (208 mil), surface-mount, RoHS-compliant, JEDEC MS-012AC standard.

Pin/Terminal	Circuit Role	Design Meaning
CS#	Chip Select Input	Active-low enable for SPI command sequence; must be deasserted between commands to reset internal state machine.
SCK	Serial Clock Input	Provides timing reference for all SPI transfers; supports up to 108 MHz in Quad mode with controlled slew rate.
IO0 (SI)	Serial Data I/O (Input/Output)	Primary data line for Single I/O; shares bidirectional function with IO1–IO3 in Dual/Quad modes; requires pull-up for tri-state recovery.
IO1 (SO)	Serial Data I/O (Output/Input)	Second data line in Dual/Quad modes; outputs status/data during read; inputs address/mode bits during program/erase.
IO2 (WP#)	Write Protect Input	Hardware lock for top/bottom block protection; active-low; disabled when Quad I/O is enabled per configuration register.
IO3 (HOLD#)	Command Hold Input	Suspends ongoing read/program/erase without clock stop; resumes from same address after deassertion; disabled in Quad mode.
VCC	Power Supply	Single 2.6–3.6 V supply; decoupling capacitor (0.1 µF) required within 5 mm of pin for stable high-speed operation.
VSS	Ground	Signal and core ground reference; must be connected to low-impedance PCB plane to minimize noise coupling into SPI signals.

Key Features

Feature	Design Value
Quad Read Mode	Enables 54 MB/s throughput via 4-bit parallel data transfer per clock cycle, reducing instruction fetch latency vs. legacy SPI flash.
Program/Erase Suspend	Allows host CPU to interrupt background programming or erasing to service higher-priority interrupts, then resume from exact byte offset.
Three 256-byte OTP Registers	Stores immutable keys, calibration data, or device-specific configuration; permanently locked after first write to prevent tampering.
Pointer-Based Block Protection	Configurable 4 kB–full-memory protection range set by software pointer, enabling dynamic lockdown of firmware update partitions.
Serial Flash Discoverable Parameters (SFDP)	JESD216B-compliant parameter table accessible via standard command, enabling automatic driver initialization without hard-coded timing values.

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
S25FL064L0XNFI010	Successor device; 64 Mbit density, 133 MHz Quad Read, 256-byte page, 65 nm process, enhanced SFDP v1.6 support.	Supports newer MCU drivers requiring JESD216B rev. C; lacks HOLD#/WP# in Quad mode (same as S25FL164K).	Select for new designs requiring extended lifecycle, higher speed, and updated security features; footprint-compatible with SOIC-8 variant.
MX25L6433FZNI-10G	64 Mbit, 104 MHz Quad Read, 2.7–3.6 V, 100K endurance, but no OTP security registers or pointer-based protection.	Lacks hardware-enforced firmware partitioning; relies on software-only protection schemes vulnerable to runtime attacks.	Acceptable for cost-sensitive consumer applications where security is managed externally; not suitable for certified industrial or automotive use.

Compared with S25FL064L and MX25L6433F, the S25FL164K0XNFI010 offers mature Industrial Plus qualification and proven field reliability but lacks the speed and SFDP enhancements of the successor; MX25L6433F trades security for lower BOM cost in non-critical systems.

FAQ

Is S25FL164K0XNFI010 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, it is excluded from future roadmap investment and long-term availability guarantees.

What package does S25FL164K0XNFI010 use?

S25FL164K0XNFI010 uses an 8-lead SOIC package with 208 mil body width (JEDEC MS-012AC), pin-compatible with other S25FL1-K variants in the same footprint. It is not offered in WSON or BGA variants under this specific part number.

Does this device support Execute-in-Place (XIP)?

Yes. Its Quad Read mode delivers 54 MB/s sustained throughput and supports Continuous and Wrapped Read modes-both optimized for low-overhead instruction fetch. Combined with configurable dummy cycles and fast initial access time, it enables reliable XIP operation without external RAM buffering.

How is security implemented in S25FL164K0XNFI010?

Security includes three 256-byte OTP registers for immutable key storage, top/bottom block protection with pointer-based range selection, hardware WP#/HOLD# inputs, non-volatile status register locks, and an 8-byte unique device ID. All protection modes can be configured via standard SPI commands without additional hardware.
