Product details
Overview
S25FL116K0XMFN041 from Cypress Semiconductor is a 16-Mbit (2 Mbyte), 3.0 V serial NOR flash memory with SPI Multi-I/O interface, supporting Normal Read (50 MHz), Fast/Dual/Quad Read (108 MHz), uniform 4-kB sector and 64-kB block erase, and Execute-In-Place (XIP) operation. It operates across –40 °C to +105 °C, features three 256-byte OTP security registers, and is packaged in an 8-lead SOIC (208 mil) - used for firmware storage and boot code execution in industrial microcontroller systems.
For engineers reviewing the S25FL116K0XMFN041 datasheet, S25FL116K0XMFN041 pinout, S25FL116K0XMFN041 application, or S25FL116K0XMFN041 equivalent, key selection criteria include quad I/O read bandwidth (54 MB/s), 100K program-erase endurance, 20-year data retention, hardware/software write protection, and migration path to S25FL064L for new designs.
Technical Context
This SPI flash implements JEDEC-standard Serial Flash Discoverable Parameters (SFDP) for automatic configuration and supports four I/O modes: Single (SIO), Dual (DIO), Quad (QIO), and continuous/wrapped read for efficient XIP. The device uses 90 nm floating gate technology and integrates dedicated status register bits for volatile/non-volatile configuration control.
It provides full command compatibility with legacy S25FL-K families but omits unsupported opcodes (e.g., Quad Page Program 32h, Half-Block Erase 52h) and adds variable dummy cycle latency for optimized timing at high clock rates. Hardware protection is enabled via WP# and HOLD# pins, while QIO mode disables those functions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2 Mbyte) - sufficient for compact boot firmware and parameter storage in resource-constrained MCUs |
| Interface | SPI Multi-I/O (SIO/DIO/QIO) - reduces pin count vs parallel NOR while enabling up to 54 MB/s read throughput |
| Max Read Rate | 108 MHz Quad Read - delivers 54 MB/s continuous transfer, matching x16 parallel NOR performance with 6-pin interface |
| 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 deployments |
| Supply Voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and tolerant of brown-out conditions |
| Temperature Range | –40 °C to +105 °C (Industrial Plus) - qualified for extended thermal environments without derating |
Pinout & Package
Package: 8-lead SOIC (208 mil), footprint code SOC008 per Cypress ordering nomenclature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable for SPI command initiation; must be held low during entire transaction |
| SCK | Serial Clock | Input clock synchronizing all SPI transfers; supports modes 0 and 3 (CPOL/CPHA) |
| IO0 (SI) | Serial Input / Data In | Primary input for commands, addresses, and program data in SIO/DIO/QIO modes |
| IO1 (SO) | Serial Output / Data Out | Primary output for read data; bidirectional in DIO/QIO for dual/quad data transfer |
| WP# | Write Protect | Hardware lock for status register and memory array; active-low, disabled in QIO mode |
| HOLD# | Hold Control | Suspends ongoing command mid-execution; resumes on next SCK edge; disabled in QIO mode |
| VCC | Power Supply | Single 2.7–3.6 V supply powering core and I/O circuits; no separate VIO required |
| VSS | Ground | Common reference for all signals and internal circuitry; requires low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read (QIO) Mode | Enables 4-bit-per-cycle transfers at 108 MHz, achieving 54 MB/s - eliminates need for wider parallel interfaces |
| Program/Erase Suspend | Allows interruption of long erase or program operations to service higher-priority host requests, improving real-time responsiveness |
| Three 256-byte OTP Security Registers | Provides immutable storage for keys, calibration data, or device identity - protected by lock-down until power cycle |
| Continuous & Wrapped Read Modes | Reduces instruction fetch overhead in XIP applications: continuous mode minimizes command latency; wrapped mode optimizes cache-line fills |
| JEDEC SFDP Compliance | Enables automatic configuration discovery by host bootloader or OS without hard-coded timing 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 |
|---|---|---|---|
| S25FL064L | 64 Mbit density, 133 MHz Quad Read, 2.7–3.6 V, same SOIC-8 package, enhanced SFDP v1.6 support | Recommended for new designs requiring higher capacity and faster timing margins; supersedes S25FL1-K family per Cypress migration note | Select when upgrading firmware size or needing future-proof JEDEC compliance; pin-compatible drop-in with updated command set |
| MX25L1606E | 16 Mbit, 104 MHz Quad Read, 2.7–3.6 V, SOIC-8, lacks OTP security registers and program/erase suspend | Suitable for cost-sensitive consumer applications where security and real-time interrupt capability are non-critical | Choose only for legacy replacement where security and suspend/resume are not required; verify command subset compatibility |
Compared with S25FL116K0XMFN041, S25FL064L offers higher density and speed with full migration support, while MX25L1606E trades security and advanced features for lower unit cost - making the former ideal for design refreshes and the latter acceptable only in non-critical, cost-driven use cases.

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 IoT applications.
The S25FL1-K family was designed for high-reliability, SPI-based code storage in space-constrained embedded systems requiring XIP, secure boot, and extended temperature operation - targeting industrial automation and automotive subsystems prior to migration to the S25FL-L series.
FAQ
Is S25FL116K0XMFN041 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 fully functional and supported for existing production, new projects should adopt the S25FL-L family for improved performance, longevity, and technical support.
What are the critical differences between S25FL116K0XMFN041 and S25FL064L?
S25FL064L doubles the density to 64 Mbit, increases Quad Read speed to 133 MHz, adds SFDP v1.6 support, and maintains identical SOIC-8 packaging and command compatibility. It also introduces enhanced security features and extended lifecycle support - making it a direct, forward-compatible upgrade path per Cypress documentation.
Does S25FL116K0XMFN041 support hardware write protection independent of software commands?
Yes. The WP# pin provides hardware-level write protection for both the memory array and status register. When asserted low, it locks protected sectors regardless of software commands - a critical feature for fail-safe boot code integrity in safety-critical systems.
Can S25FL116K0XMFN041 operate in Quad I/O mode while using HOLD# or WP# functions?
No. When Quad I/O mode is enabled, the WP# and HOLD# pins are repurposed as IO2 and IO3, disabling their hardware protection and suspend functionality. Designers must choose between maximum bandwidth (QIO) or hardware control features (SIO/DIO with WP#/HOLD# active).
