Product details

Overview

S25FL164K0XBHI030 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 systems.

For engineers reviewing the S25FL164K0XBHI030 datasheet, S25FL164K0XBHI030 pinout, S25FL164K0XBHI030 application, or S25FL164K0XBHI030 equivalent, key selection criteria include quad I/O read performance, industrial-plus temperature support (−40 °C to +105 °C), hardware/software write protection, SFDP compliance, and migration path to S25FL064L.

Technical Context

This device implements a JEDEC-standard SPI Multi-I/O (MIO) interface with configurable clock polarity/phase (modes 0 and 3), supporting Single, Dual, and Quad I/O protocols using shared IO0–IO3 pins. The QIO mode disables WP# and HOLD# functionality, requiring software-based protection when enabled.

It integrates three 256-byte one-time-programmable (OTP) security registers, pointer-based block protection, and an 8-byte unique ID. Memory organization includes a 64-Mbit array with 4-kB sectors (1024 total), 64-kB blocks (128 total), and SFDP v1.5-compliant parameter tables accessible via standard command 5A_h.

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.
Interface	SPI Multi-I/O (SIO/DIO/QIO) - reduces pin count vs parallel NOR while maintaining XIP-capable throughput.
Max Read Speed	108 MHz Quad Read - enables 54 MB/s burst reads, matching x16 parallel NOR latency for cache-line fills.
Erase Granularity	Uniform 4 kB sectors and 64 kB blocks - allows fine-grained firmware updates without disturbing adjacent code sections.
Cycling Endurance	100K program-erase cycles - sufficient for field firmware upgrades over 10+ years of operation.
Data Retention	20 years minimum at +85 °C - ensures long-term reliability in industrial control and automotive infotainment modules.
Supply Voltage	2.7 V to 3.6 V - compatible with standard 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 and factory automation environments.

Pinout & Package

Package: 8-lead SOIC (208 mil), package code SOC008 per Cypress ordering information.

Pin/Terminal	Circuit Role	Design Meaning
CS#	Chip Select Input	Active-low enable for command decoding; must be held low for entire command sequence including address and data phases.
SCK	Serial Clock Input	Provides timing for all SPI transfers; supports modes 0 and 3; max 108 MHz in QIO mode.
IO0 (SI)	Serial Data I/O	Primary bidirectional data line; used for instruction, address, and data in SIO; first bit in DIO/QIO transfers.
IO1 (SO)	Serial Data I/O	Second bidirectional data line; active in DIO/QIO modes; carries even-address bits in Quad Read.
IO2 (WP#)	Write Protect Input / I/O	Hardware-level write lock; functional only in SIO/DIO modes; disabled when QIO is enabled.
IO3 (HOLD#)	Hold Input / I/O	Suspends ongoing command mid-execution; resumes on next SCK edge; disabled in QIO mode.
VCC	Power Supply	Single 2.7–3.6 V supply powers core and I/O; no separate VIO required.
VSS	Ground	Common reference for all signals; requires low-inductance connection to minimize read noise.

Key Features

Feature	Design Value
Quad Read (QIO) Mode	Enables 54 MB/s burst reads using all four I/O lines, eliminating need for parallel NOR in XIP-critical applications.
Program/Erase Suspend	Allows background erase or program to pause for high-priority read access-critical for real-time firmware updates.
Security Registers (OTP)	Three 256-byte regions store immutable keys, calibration data, or device identity-prevents cloning or unauthorized reprogramming.
SFDP v1.5 Compliance	Self-describing parameters (read latency, erase sizes, voltage ranges) allow automatic driver configuration without hard-coded values.
Variable Dummy Cycles	Configurable latency in read commands balances speed vs. signal integrity across PCB trace lengths and temperature ranges.

Applications

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, 256-byte page, 133 MHz clock, 100K cycles, same 8-lead SOIC (208 mil) footprint.	Supports higher clock rates and enhanced SFDP v1.6; adds volatile configuration register; identical pinout and command set.	Select for new designs requiring extended longevity, improved read bandwidth, and Cypress's current production roadmap.
MX25L6433FZNI-10G	64 Mbit, 104 MHz Quad Read, 2.7–3.6 V, 100K cycles, 8-lead SOIC (208 mil); no OTP security registers or pointer-based protection.	Lacks dedicated security registers and SFDP v1.5; uses simpler status register protection; lower max clock rate limits XIP performance.	Consider where cost sensitivity outweighs security needs and where legacy drivers lack SFDP parsing capability.

Compared with S25FL064L0XMFI000, this part offers identical density and package but lower max clock rate and retired status; versus MX25L6433FZNI-10G, it provides stronger security and standardized parameter discovery at the cost of vendor lock-in and end-of-life risk.

Manufacturer

Cypress Semiconductor, now part of Infineon Technologies, designs high-performance memory and microcontroller solutions for industrial, automotive, and communications markets.

The S25FL1-K family targets cost-sensitive, space-constrained embedded systems needing reliable XIP-capable flash with enhanced security and multi-I/O flexibility-prioritizing firmware integrity and upgrade resilience.

FAQ

Is S25FL164K0XBHI030 still in production?

No. Cypress officially retired the S25FL1-K family and does not recommend it for new designs. Production ended per Document Number 002-00497 Rev. *H. Aetrix Electronics maintains limited legacy stock for continuity support, but long-term supply relies on controlled allocation and migration planning to S25FL064L.

What is the function of the IO2 and IO3 pins in Quad I/O mode?

In Quad I/O mode, IO2 and IO3 serve as bidirectional data lines carrying bits 2 and 3 of each 4-bit nibble. Their hardware protection functions (WP# and HOLD#) are disabled per datasheet Section 2.7–2.8; protection must be implemented via software commands or external logic when QIO is active.

Does S25FL164K0XBHI030 support JEDEC-standard SFDP?

Yes. It implements SFDP v1.5 (JESD216B), exposing read latency, erase block sizes, voltage ranges, and timing parameters in a standardized, discoverable format. This enables automatic driver initialization without hardcoded constants, improving portability across host platforms.

Can this device replace S25FL132K in the same PCB layout?

No. Although both belong to the S25FL1-K family, S25FL164K has 64 Mbit density versus 32 Mbit for S25FL132K. They share the same 8-lead SOIC (208 mil) package option (SOC008), but memory map size and timing margins differ; firmware must be validated for address space and erase cycle count compatibility.
