Product details

Overview

S25FL164K0XBHV020 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. It operates across –40 °C to +105 °C (Industrial Plus), features three 256-byte OTP security registers, 8-byte unique ID, and Execute-In-Place (XIP) capability for embedded code storage in microcontroller boot applications.

For engineers reviewing the S25FL164K0XBHV020 datasheet, S25FL164K0XBHV020 pinout, S25FL164K0XBHV020 application, or S25FL164K0XBHV020 equivalent, key selection criteria include quad-speed read performance, hardware/software write protection granularity, SFDP compliance, temperature-grade validation, and migration path to S25FL064L for new designs.

Technical Context

This device implements a 90 nm floating-gate NOR architecture with serial peripheral interface supporting SPI modes 0 and 3. It delivers up to 54 MB/s continuous data transfer via Quad Read commands and supports wrapped/continuous read modes optimized for XIP execution and cache-line refill efficiency.

The memory includes dual protection mechanisms: non-volatile status register bits and hardware WP#/HOLD# inputs (disabled during Quad I/O mode), plus pointer-based block protection (S25FL164K only) and lock-down-until-power-cycle security. Its 2.6 V–3.6 V supply range accommodates industrial-plus and AEC-Q100 Grade 2 automotive operation.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	64 Mbit (8 Mbyte) - sufficient for full firmware images in mid-tier MCUs and boot code storage.
Read Throughput	54 MB/s max (Quad Read @ 108 MHz) - matches parallel NOR bandwidth while using only 6 pins.
Erase Granularity	Uniform 4 kB sectors and 64 kB blocks - enables fine-grained firmware updates without full chip erase.
Endurance & Retention	100K program-erase cycles / 20-year data retention - validated for long-life industrial control and automotive ECUs.
Operating Voltage	2.6 V–3.6 V - compatible with 3.3 V systems and tolerant of brown-out conditions down to 2.6 V.
Temperature Range	–40 °C to +105 °C (Industrial Plus) - qualified for under-hood and high-ambient industrial environments.
Security Features	Three 256-byte OTP security registers + 8-byte unique ID + pointer-based block protection - enables secure boot and device authentication.

Pinout & Package

Package: 8-lead SOIC (208 mil), standardized footprint per SOC008 specification. Compatible with reflow and wave soldering per JEDEC J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
CS#	Chip Select Input	Active-low enable for command initiation; must be held low for entire command sequence.
SCK	Serial Clock Input	Provides timing for all SPI transfers; supports up to 108 MHz in Quad Read mode.
IO0 (SI)	Serial Data I/O 0	Primary data line for Single/Dual I/O; functions as SI in standard SPI mode.
IO1 (SO)	Serial Data I/O 1	Primary output in Single I/O; bidirectional in Dual/Quad modes for 2-/4-bit data transfer.
IO2 (WP#)	Write Protect Input	Hardware-level protection override; disables program/erase when asserted low (inactive during Quad I/O).
IO3 (HOLD#)	Command Hold Input	Suspends ongoing command at any clock cycle; resumes on deassertion (disabled during Quad I/O).
VCC	Power Supply	Single 2.6–3.6 V supply; powers core logic and I/O buffers; requires local 100 nF decoupling.
VSS	Ground	Signal and power ground reference; must be connected to system common ground plane.

Key Features

Feature	Design Value
Quad Read (QIO) Mode	Enables 54 MB/s throughput using all four I/O lines, eliminating need for wider parallel interfaces in space-constrained designs.
Execute-In-Place (XIP)	Continuous and wrapped read modes reduce instruction fetch latency, enabling direct MCU code execution from flash without RAM copy.
Program/Erase Suspend	Allows background operations (e.g., real-time logging) to pause flash programming or erasing and resume without data loss.
SFDP Compliance	JEDEC JESD216B-compliant Serial Flash Discoverable Parameters allow automatic configuration by host bootloader without hard-coded timing values.
Pointer-Based Protection	S25FL164K-exclusive feature enabling dynamic definition of protected memory ranges via status register pointers, not fixed address boundaries.

Applications

Industrial PLC Firmware Storage

Automotive Body Control Module (BCM)

Use Scenario: Storing field-upgradable firmware and calibration tables in programmable logic controllers operating in factory-floor environments with wide thermal swings.

IC Role / Device Role / Timing Role: Non-volatile code storage with XIP support and robust erase/write endurance for frequent over-the-air updates.

Use Value: 100K endurance and 20-year retention ensure multi-decade service life; Industrial Plus temperature rating guarantees reliability at +105 °C ambient.

Use Scenario: Boot code and safety-critical configuration storage in body control modules requiring AEC-Q100 Grade 2 qualification.

IC Role / Device Role / Timing Role: Primary boot flash for microcontrollers, leveraging Quad Read speed to meet automotive boot-time requirements.

Use Value: 54 MB/s read rate reduces boot latency; hardware WP# and OTP registers support ASIL-B functional safety partitioning.

Medical Diagnostic Imaging UI

Network Edge Router Boot Image

Use Scenario: Storing GUI assets, firmware, and regulatory-compliant diagnostic algorithms in portable imaging devices with strict EMI and power constraints.

IC Role / Device Role / Timing Role: Low-pin-count, high-reliability flash for secure, compact HMI subsystems with infrequent but critical firmware updates.

Use Value: 8-byte unique ID enables device-specific licensing; three OTP registers store cryptographic keys and calibration certificates.

Use Scenario: Hosting primary bootloader and fail-safe recovery image in carrier-grade edge routers requiring zero-downtime firmware upgrades.

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
S25FL064L0XMFI000	Successor device: 64 Mbit, 133 MHz Quad Read (66.5 MB/s), 1.8 V–3.6 V supply, enhanced SFDP v1.6, no HOLD#/WP# in QIO mode.	Designed for new designs requiring higher speed, lower voltage flexibility, and extended lifecycle support; not pin-compatible with S25FL164K.	Select for new projects needing active technical support, longer product availability, and improved power efficiency.
MX25L6433FZNI-10G	64 Mbit, 104 MHz Quad Read (52 MB/s), 2.7 V–3.6 V, standard SPI, no pointer-based protection or Industrial Plus temp grade.	Cost-optimized alternative for commercial-temp applications where advanced security and extended temperature are not required.	Consider only for legacy cost-sensitive designs where S25FL164K's security and temperature specs are unnecessary.

Compared with S25FL164K0XBHV020, S25FL064L offers higher speed and broader voltage range but requires PCB redesign; MX25L6433F provides basic functionality at lower cost but lacks OTP security, pointer protection, and Industrial Plus qualification.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) is a fabless semiconductor company specializing in microcontrollers, connectivity solutions, and non-volatile memory for industrial, automotive, and consumer applications.

The S25FL1-K family was designed to deliver high-speed, secure, and temperature-hardened serial NOR flash for embedded boot and firmware storage where pin count, power, and reliability are critical constraints.

FAQ

Is S25FL164K0XBHV020 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 Aetrix maintaining controlled inventory and traceable sourcing for continuity support.

What package does S25FL164K0XBHV020 use?

S25FL164K0XBHV020 uses an 8-lead SOIC package with 208-mil body width (SOC008 footprint). This is distinct from the 16-lead SOIC option listed for other S25FL164K variants - the 'X' in the suffix confirms the 8-lead SOIC (208 mil) configuration.

Does this device support Quad I/O mode with hardware write protection active?

No. When Quad I/O mode is enabled, the WP# and HOLD# pins (IO2 and IO3) are repurposed as data lines and hardware protection is disabled. Write protection must then be managed exclusively via non-volatile status register bits and software commands.

Can S25FL164K0XBHV020 be used in automotive applications?

Yes - it is qualified for AEC-Q100 Grade 2 (–40 °C to +105 °C), making it suitable for under-hood and cabin applications such as body control modules and instrument clusters, provided design-in occurred prior to its retirement notice.
