Product details
Overview
S25FL164K0XMFB000 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, 20-year data retention, and hardware/software write protection - deployed in industrial control firmware storage and boot code execution.
For engineers reviewing the S25FL164K0XMFB000 datasheet, S25FL164K0XMFB000 pinout, S25FL164K0XMFB000 application, or S25FL164K0XMFB000 equivalent, key selection criteria include Quad I/O timing compliance, security register OTP configuration, AEC-Q100 Grade 2 temperature support (–40°C to +105°C), and migration path to S25FL064L for new designs.
Technical Context
The S25FL164K0XMFB000 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 Industrial Plus (–40°C to +105°C) and Automotive Grade 2 ranges.
It uses a 4–6 signal interface (CS#, SCK, IO0–IO3) with dual-role pins: WP#/IO2 and HOLD#/IO3 function as both control inputs and I/O lines in Dual/Quad modes. When Quad mode is active, WP# and HOLD# are disabled per protocol specification, and all four I/O lines operate bidirectionally at up to 108 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 Mbyte) - sufficient for full MCU boot image + firmware + configuration data in space-constrained embedded systems |
| Interface Protocol | SPI Multi-I/O (SIO/DIO/QIO) - reduces pin count vs parallel NOR while maintaining XIP-capable throughput |
| Max Read Speed | 54 MB/s (Quad Read @ 108 MHz, –40°C to +105°C) - matches x16 parallel NOR performance with 70% fewer signals |
| Erase Granularity | Uniform 4 kB sectors and 64 kB blocks - enables fine-grained firmware updates without disturbing adjacent code sections |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - validated for industrial field-deployed equipment with infrequent reprogramming |
| Supply Voltage | 2.6 V to 3.6 V - compatible with 3.3 V logic rails and tolerant of brown-out conditions down to 2.6 V |
| Security Features | Three 256-byte OTP security registers + 8-byte unique ID + pointer-based block protection - enables secure boot key storage and firmware anti-rollback |
Pinout & Package
Package: 8-lead SOIC (208 mil), body size 5.3 mm × 5.3 mm, standard JEDEC MS-012AC, RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable for command initiation; must be held low for entire command duration including dummy cycles |
| SCK | Serial Clock Input | Edge-triggered clock (mode 0/3); max 108 MHz in Quad mode; defines timing for all I/O transfers |
| IO0 (SI) | Serial Input / I/O Line 0 | Primary data input in SIO mode; bidirectional in DIO/QIO; used for instruction/address/data during programming |
| IO1 (SO) | Serial Output / I/O Line 1 | Primary data output in SIO mode; bidirectional in DIO/QIO; carries read data and status responses |
| WP# / IO2 | Write Protect Input / I/O Line 2 | Hardware lock for top/bottom memory blocks when enabled; repurposed as I/O2 in Dual/Quad modes |
| HOLD# / IO3 | Hold Input / I/O Line 3 | Suspends ongoing command mid-execution (e.g., during erase); repurposed as I/O3 in Quad mode |
| VCC | Power Supply | Single 2.6–3.6 V supply; powers core logic and I/O buffers; decoupling capacitor required per datasheet layout guidelines |
| VSS | Ground | Signal and power ground 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 execution of ARM Cortex-M4 firmware without external RAM buffering |
| Program/Erase Suspend & Resume | Allows host to interrupt long erase operations (e.g., 500 ms 64 kB erase) to service higher-priority interrupts |
| Three 256-byte OTP Security Registers | Stores cryptographic keys and boot policy flags with irreversible write locking - meets IEC 62443-3-3 SL2 requirements |
| JEDEC SFDP Support (JESD216B) | Permits automatic configuration of read latency, dummy cycles, and address width by host bootloader without hard-coded parameters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPI NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL064L0XMFI000 | Successor device with 64 Mbit density, 133 MHz Quad Read, 256-byte page buffer, and enhanced SFDP v1.6 support | Requires updated bootloader for extended dummy cycle handling and new status register bit mapping | Select for new designs requiring longer product lifecycle, higher speed, and JEDEC JESD216D compliance |
| MX25L6433FZNI-10G | 64 Mbit SPI NOR with 104 MHz Quad Read, no OTP security registers, no AEC-Q100 qualification | Lacks hardware-based secure boot features and automotive temperature validation | Acceptable for cost-sensitive industrial applications where security and extended temp are not required |
Compared with S25FL164K0XMFB000, the S25FL064L offers measurable throughput gain (+23%) and formal lifecycle support, while MX25L6433F trades security and qualification for lower unit cost - making it viable only where threat model excludes firmware tampering and ambient temperature stays within commercial range.

FAQ
Is S25FL164K0XMFB000 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and identifies S25FL064L as the factory-recommended migration path. While fully functional and supported for existing production, new projects should adopt the S25FL064L for guaranteed long-term availability, improved specs, and updated documentation.
What package does S25FL164K0XMFB000 use, and is it pin-compatible with other S25FL1-K variants?
S25FL164K0XMFB000 uses an 8-lead SOIC (208 mil) package (SOC008). It shares footprint compatibility with S25FL132K in the same package but differs from S25FL116K (which uses 150-mil SOIC). Pinout is identical across all SOIC-packaged S25FL1-K devices, enabling drop-in replacement within same density tier.
Does S25FL164K0XMFB000 support Quad I/O mode at full speed across its entire temperature range?
Yes. Quad Read operates at 108 MHz from –40°C to +105°C per datasheet specifications. The 54 MB/s maximum transfer rate is guaranteed across Industrial Plus and Automotive Grade 2 temperature ranges, provided VCC remains within 2.6 V–3.6 V and layout follows Cypress's signal integrity guidelines for high-speed SPI routing.
How is security implemented in S25FL164K0XMFB000, and can it be used for secure boot?
Security relies on three 256-byte OTP registers, 8-byte unique device ID, and pointer-based block protection. These allow storage of immutable cryptographic keys and boot policy flags. Combined with non-volatile status register lock bits and hardware WP# pin, it supports certified secure boot chains - confirmed in Cypress application note AN98567 for Trusted Firmware-A integration.
