Product details
Overview
S25FL116K0XNFIQ10 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 uses 90 nm floating gate technology and operates from 2.7 V to 3.6 V.
For engineers reviewing the S25FL116K0XNFIQ10 datasheet, S25FL116K0XNFIQ10 pinout, S25FL116K0XNFIQ10 application, or S25FL116K0XNFIQ10 equivalent, key selection considerations include quad-read throughput (54 MB/s), 100K program-erase endurance, 20-year data retention, hardware/software write protection, and SOIC-8 (150 mil) package compatibility with legacy FL-K footprints.
Technical Context
This device implements JEDEC-standard SPI command protocols with support for clock polarity/phase modes 0 and 3, Serial Flash Discoverable Parameters (SFDP), and variable dummy cycle latency for optimized read timing. It features dual and quad I/O modes using shared IO0–IO3 pins, where WP# and HOLD# become functional only in single/dual mode.
The memory array is organized as 32 sectors of 4 kB each, with dedicated security registers (3 × 256-byte OTP), 8-byte unique ID, and non-volatile/volatile configuration register options. Erase suspend/resume and program suspend/resume enable real-time background operations without host interruption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2 Mbyte) - fixed capacity for compact firmware storage in space-constrained designs |
| Interface | SPI Multi-I/O (SIO/DIO/QIO) - reduces pin count vs parallel NOR while maintaining XIP performance |
| Max Read Speed | 54 MB/s (Quad Read @ 108 MHz) - enables cache-line refill and real-time code execution |
| Erase Granularity | 4 kB sector / 64 kB block - balances update flexibility with wear leveling efficiency |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - meets long-life industrial deployment requirements |
| Supply Voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and brown-out tolerant operation |
| Operating Temp | −40 °C to +85 °C (Industrial) - validated for uncontrolled ambient environments in factory automation |
Pinout & Package
Package: 8-lead SOIC (150 mil), RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable for command initiation; must be held low during full command sequence |
| SCK | Serial Clock Input | Edge-triggered clock (mode 0/3); max 108 MHz for QIO, defines data transfer timing |
| IO0 (SI) | Serial Data I/O (Input/Output) | Primary bidirectional data line; used for instruction/address/data in all I/O modes |
| IO1 (SO) | Serial Data I/O (Output/Input) | Second bidirectional line; active in Dual/Quad Read and Program; replaces SO in legacy mode |
| IO2 (WP#) | Write Protect Input | Hardware-level sector protection when asserted low; disabled in Quad I/O mode |
| IO3 (HOLD#) | Command Hold Input | Suspends ongoing command at any clock edge; resumes on deassertion; disabled in Quad I/O mode |
| VCC | Power Supply | Single 2.7–3.6 V supply; powers core and I/O circuits; decoupling required per layout guidelines |
| VSS | Ground | Signal and power return reference; requires low-impedance connection to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read (QIO) | 54 MB/s continuous throughput enables efficient XIP and cache-line fill without parallel bus overhead |
| Program/Erase Suspend | Allows background erase or program to pause/resume mid-operation, enabling responsive host multitasking |
| Security Registers | Three 256-byte OTP regions protect boot code, keys, or calibration data from overwrite or readout |
| Continuous Read Mode | 8-clock access overhead supports low-latency random reads ideal for interrupt vector fetching |
| JEDEC SFDP Support | Enables automatic configuration discovery by host bootloader, eliminating hardcoded timing parameters |

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 |
|---|---|---|---|
| S25FL064L0XNFIQ10 | 64 Mbit density, 133 MHz Quad Read, 1.8 V / 3.0 V dual supply, enhanced SFDP v1.6 | Higher density and speed; supports newer controllers with extended command sets (e.g., 4-byte addressing) | Select for new designs requiring >16 Mbit capacity or future-proofing against obsolescence |
| MX25L1606EM1I-12G | 16 Mbit, 85 MHz Quad Read, 2.7–3.6 V, no program/erase suspend, no OTP security registers | Lacks suspend/resume and hardware security; simpler command set; lower cost | Choose for cost-sensitive, non-security-critical applications where full S25FL1-K feature set is unused |
Compared with S25FL116K0XNFIQ10, S25FL064L0XNFIQ10 offers scalable capacity and modern command compatibility but requires layout revision, while MX25L1606EM1I-12G sacrifices advanced reliability and security features for baseline functionality and price.

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 consumer applications.
The S25FL1-K family was designed for high-reliability embedded systems needing SPI flash with XIP capability, robust data protection, and extended temperature operation-targeting applications where legacy parallel NOR footprint reduction was critical.
FAQ
Is S25FL116K0XNFIQ10 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and recommends migration to S25FL064L. It remains available for legacy production and repair, with Aetrix providing continuity support including last-time-buy planning and cross-reference guidance for drop-in or functionally upgraded alternatives.
What package does S25FL116K0XNFIQ10 use?
S25FL116K0XNFIQ10 uses an 8-lead SOIC package with 150-mil body width (SOA008), pin-compatible with prior S25FL-K and S25FL-P generations. The 'XNFIQ10' suffix confirms RoHS-compliant, industrial temperature grade, and tape-and-reel packaging.
Does it support Quad I/O mode with hardware write protection enabled?
No. In Quad I/O mode, IO2 (WP#) and IO3 (HOLD#) are repurposed as data lines, disabling hardware write protection and hold functionality. WP#/HOLD# are only active in Single I/O and Dual I/O modes, as confirmed in the signal description section of the datasheet.
Can S25FL116K0XNFIQ10 be used in automotive applications?
Yes - it is qualified to AEC-Q100 Grade 3 (−40 °C to +85 °C) and Grade 2 (−40 °C to +105 °C), making it suitable for infotainment, telematics, and body control modules. However, automotive designs should verify qualification documentation and consider S25FL064L for new projects due to its active automotive support status.
