Product details
Overview
S25FL116K0XNFIQ11 from Cypress Semiconductor is a 16-Mbit (2 Mbyte), 3.0 V serial NOR flash memory with SPI Multi-I/O interface, supporting Normal, Fast, Dual, and Quad Read modes up to 108 MHz, uniform 4-kB sector and 64-kB block erase, and Execute-In-Place (XIP) capability for embedded code storage in industrial temperature range (−40 °C to +85 °C). It is housed in an 8-lead SOIC (208 mil) package.
For engineers reviewing the S25FL116K0XNFIQ11 datasheet, S25FL116K0XNFIQ11 pinout, S25FL116K0XNFIQ11 application, or S25FL116K0XNFIQ11 equivalent, key selection considerations include quad-mode read throughput (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
The S25FL116K0XNFIQ11 implements a 90 nm floating-gate NOR architecture with JEDEC-standard SFDP support, enabling dynamic configuration discovery by host controllers. Its SPI Multi-I/O interface supports command subsets compatible with legacy S25FL-K devices while adding variable dummy-cycle latency for optimized timing across clock rates.
It integrates three 256-byte one-time-programmable (OTP) security registers, top/bottom block protection with 4-kB granularity, and dual protection mechanisms-hardware WP#/HOLD# pins and software command lock-down-ensuring robust firmware integrity in resource-constrained embedded systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2 Mbyte) - sufficient for boot code, firmware images, and configuration data in compact MCU-based systems |
| Interface | SPI Multi-I/O (x1/x2/x4) - reduces pin count vs parallel NOR while maintaining XIP performance up to 54 MB/s |
| Max Clock Rate | 108 MHz - enables quad-read transfer at 54 MB/s, matching mid-range parallel NOR bandwidth |
| Erase Granularity | Uniform 4-kB sectors and 64-kB blocks - allows fine-grained firmware updates without full chip erase |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - meets long-life requirements for industrial control and networking equipment |
| 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 |
| Operating Temp | −40 °C to +85 °C - qualified for industrial-grade operation without derating |
Pinout & Package
Package: 8-lead SOIC (208 mil), body size 5.3 mm × 5.3 mm, pitch 1.27 mm, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable for SPI command sequence; must be asserted before SCK edge to initiate communication |
| SCK | Serial Clock Input | Provides timing reference for all SPI transfers; supports modes 0 and 3 (CPOL/CPHA) |
| IO0 (SI) | Serial Data Input / I/O | Primary data input during commands (e.g., Page Program); bidirectional in Dual/Quad modes |
| IO1 (SO) | Serial Data Output / I/O | Primary data output during reads; bidirectional in Dual/Quad modes; tri-stated when CS# high |
| WP# | Write Protect Input | Hardware lock for status register and security registers; active-low, overrides software protection when asserted |
| HOLD# | Hold Input | Suspends ongoing command (read/program/erase) without losing internal state; resumes on deassertion |
| VCC | Power Supply | Single 2.7–3.6 V supply for core and I/O; no separate VIO required |
| VSS | Ground | Reference return for all signals and power; requires low-impedance connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read Mode | 54 MB/s continuous throughput - eliminates bottleneck for XIP execution in ARM Cortex-M4/M7 applications |
| Program/Erase Suspend | Interrupts active erase or program to service higher-priority reads - enables real-time response in multitasked firmware |
| Security Registers | Three 256-byte OTP areas - store cryptographic keys, calibration data, or device-specific credentials with irreversible write protection |
| Block Protection Range | Configurable 4-kB to full-array protection - prevents accidental overwrite of bootloader or critical configuration sectors |
| Continuous Read Mode | 8-clock overhead per access - minimizes latency for random instruction fetches in XIP mode |
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 |
|---|---|---|---|
| S25FL064L | 64-Mbit density, 133 MHz max clock, enhanced SFDP v1.6, 1.8 V / 3.0 V dual supply option | Supports larger firmware images and faster boot times; requires updated PCB layout for 8-pin WSON or 24-ball BGA packages | Select for new designs requiring higher density, longer product lifecycle, and extended voltage flexibility |
| MX25L1606E | 16-Mbit, 85 MHz max clock, no Quad Read suspend/resume, no OTP security registers, JEDEC JESD216A SFDP | Lacks hardware HOLD#/WP# integration and security features; suitable only for cost-sensitive non-security applications | Consider only if design lacks requirement for firmware integrity enforcement or real-time suspend capability |
Compared with S25FL064L, the S25FL116K0XNFIQ11 offers lower density and legacy SFDP but fits existing SOIC footprints; versus MX25L1606E, it delivers superior security, suspend functionality, and 23% higher quad-read bandwidth-critical for deterministic XIP performance.

Manufacturer
Cypress Semiconductor (now part of Infineon Technologies) designs high-performance, low-power memory and microcontroller solutions for industrial, automotive, and communications markets.
The S25FL1-K family was engineered to deliver SPI NOR flash with enhanced XIP efficiency, integrated security, and seamless migration from legacy parallel and serial NOR-targeting space-constrained, real-time embedded systems.
FAQ
Is S25FL116K0XNFIQ11 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. It remains available for legacy support and last-time buys, but lacks long-term roadmap assurance, newer process node benefits, or updated SFDP compliance beyond JESD216B.
What package does S25FL116K0XNFIQ11 use?
S25FL116K0XNFIQ11 uses an 8-lead SOIC package with 208-mil width (SOC008), measuring 5.3 mm × 5.3 mm with 1.27 mm lead pitch. This footprint is pin-compatible with other S25FL1-K variants in the same package option and supports standard reflow soldering profiles for industrial assembly.
Does S25FL116K0XNFIQ11 support Quad I/O mode with WP# and HOLD# active?
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 functions. These features remain fully operational only in Single I/O and Dual I/O modes, requiring mode selection via Status Register bit configuration.
How is security implemented in S25FL116K0XNFIQ11?
Security is implemented via three 256-byte One-Time-Programmable (OTP) registers, non-volatile status register bits controlling protection modes, software command locks, hardware WP# assertion, and lock-down until power cycle. Unique 8-byte device ID enables secure provisioning, and pointer-based protection (in higher-density variants) is not present in this 16-Mbit part.
