Product details
Overview
S25FL164K0XMFI010 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 controllers.
For engineers reviewing the S25FL164K0XMFI010 datasheet, S25FL164K0XMFI010 pinout, S25FL164K0XMFI010 application, or S25FL164K0XMFI010 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 command set with support for modes 0 and 3, SFDP v1.5 (JESD216B), and configurable volatile/non-volatile status registers. It uses 90 nm floating gate technology and supports execute-in-place (XIP) via Continuous and Wrapped Read modes with programmable dummy cycles.
Hardware write protection is enabled via WP# and HOLD# pins; when Quad I/O is active, those pins are repurposed as IO2/IO3 and hardware protection is disabled. Security includes three 256-byte OTP registers, 8-byte unique ID, and pointer-based block protection covering 4 kB to full memory array.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 Mbyte) - sufficient for boot code, firmware images, and configuration data in mid-tier microcontrollers |
| Interface | SPI Multi-I/O (x1/x2/x4) - reduces pin count vs parallel NOR while maintaining XIP performance |
| Max Read Speed | 54 MB/s (Quad Read @ 108 MHz) - matches or exceeds legacy x16 parallel NOR in bandwidth-critical boot paths |
| Erase Granularity | 4 kB sectors / 64 kB blocks - enables fine-grained firmware updates without disturbing adjacent code sections |
| Cycling Endurance | 100K program-erase cycles - supports field firmware upgrades over 10+ years in industrial deployments |
| Data Retention | 20 years minimum @ +85°C - ensures long-term reliability in unattended embedded systems |
| 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 automotive ECUs and high-temp industrial HMIs |
Pinout & Package
Package: 8-lead SOIC (208 mil), package code SOC008 per Cypress ordering nomenclature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable for command initiation; must be held low for entire command duration including address/data phases |
| SCK | Serial Clock | Input clock synchronizing all SPI transfers; supports up to 108 MHz with controlled slew rate for signal integrity |
| IO0 (SI) | Serial Input / Data Line 0 | Primary input for commands, addresses, and program data; functions as bidirectional I/O in Dual/Quad modes |
| IO1 (SO) | Serial Output / Data Line 1 | Primary output for read data; bidirectional in Dual/Quad modes; supports dummy cycle insertion for latency tuning |
| IO2 (WP#) | Write Protect / Data Line 2 | Hardware write lock when asserted low; repurposed as IO2 in Quad mode - disables hardware protection during QIO operation |
| IO3 (HOLD#) | Hold / Data Line 3 | Pauses ongoing command at any clock edge; repurposed as IO3 in Quad mode - eliminates suspend/resume capability in QIO |
| VCC | Core & I/O Supply | Single 2.7–3.6 V rail powers logic and I/O buffers; internal regulation ensures stable core voltage across supply range |
| VSS | Ground | Common reference for all signals; requires low-inductance connection to minimize noise coupling into read/write margins |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read with 54 MB/s throughput | Enables real-time XIP execution from flash without RAM shadowing, reducing BOM cost and power in resource-limited MCUs |
| Program/Erase Suspend & Resume | Allows background firmware update to pause on interrupt, service time-critical tasks, then resume - critical for deterministic real-time systems |
| Three 256-byte OTP security registers | Stores immutable keys, calibration data, or device-specific credentials; prevents tampering even after full chip erase |
| Pointer-based block protection | Configures write-protection ranges dynamically via status register bits - supports field-upgradable secure boot partitions |
| JEDEC SFDP v1.5 compliance | Enables automatic driver initialization in Linux/Bare Metal environments without hard-coded timing parameters or vendor-specific APIs |
| Variable dummy cycle latency | Permits optimization of initial access time vs maximum clock rate - improves boot speed in cold-start scenarios |

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 |
|---|---|---|---|
| S25FL064L0XMFI010 | Successor family; 64 Mbit, 133 MHz Quad Read, 256-byte page, 65 nm process, enhanced SFDP v1.6 | Supports higher clock rates and deeper power-down states; required for new designs per Cypress migration notice | Select for new designs requiring extended lifecycle support, lower active current (14 mA vs 16 mA @ Quad Read), and AEC-Q100 Grade 1 option |
| MX25L6433FZNI-10G | 64 Mbit, 104 MHz Quad Read, 2.7–3.6 V, no OTP security registers, no pointer-based protection | Lacks hardware security features; suitable only where firmware integrity is managed externally | Consider only if cost sensitivity outweighs security requirements and migration to S25FL064L is not feasible |
Compared with S25FL164K0XMFI010, S25FL064L0XMFI010 delivers 23% higher bandwidth and 15% lower active power but requires PCB layout revision for updated pinout; MX25L6433FZNI-10G offers footprint compatibility but omits all security and suspend/resume capabilities critical for certified systems.

Manufacturer
Cypress Semiconductor (now part of Infineon Technologies) designs high-performance, reliable non-volatile memory and microcontroller solutions for industrial, automotive, and communications markets.
The S25FL1-K family was engineered to deliver NOR flash performance parity with parallel interfaces using minimal pins, targeting cost-sensitive yet timing-critical embedded boot and firmware applications before migration to the S25FL-L series.
FAQ
Is S25FL164K0XMFI010 still 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 functional units remain available for legacy production and repair, new schematics should use S25FL064L0XMFI010 to ensure long-term supply and technical support.
What does the 'XMF' in S25FL164K0XMFI010 indicate?
The 'XMF' package code denotes an 8-pin SOIC (208 mil) body with Industrial Plus temperature grade (–40°C to +105°C) and lead-free, RoHS-compliant finish. The 'I010' suffix specifies tape-and-reel packaging with 1000-unit reels, per Cypress's standard ordering nomenclature.
Can S25FL164K0XMFI010 support Execute-in-Place (XIP) reliably?
Yes. Its 108 MHz Quad Read mode achieves 54 MB/s throughput, and Continuous/Wrapped Read modes minimize access latency. Combined with 20-year data retention and 100K endurance, it supports direct code execution in microcontrollers lacking large internal flash, such as ARM Cortex-M4/M7 derivatives with limited on-chip memory.
How does the security architecture differ between S25FL164K and S25FL132K?
S25FL164K supports pointer-based block protection (command 39h), allowing dynamic definition of protected memory ranges from 4 kB to full array size. S25FL132K lacks this feature. Both share three 256-byte OTP registers, 8-byte unique ID, and hardware/software write protection, but only S25FL164K enables runtime-configurable secure partitions.
