Product details

Overview

S25FL116K0XMFIS10 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 control and automotive infotainment systems.

For engineers reviewing the S25FL116K0XMFIS10 datasheet, S25FL116K0XMFIS10 pinout, S25FL116K0XMFIS10 application, or S25FL116K0XMFIS10 equivalent, key selection criteria include quad-read throughput (54 MB/s), 100K program-erase cycles, 20-year data retention, 2.7–3.6 V single-supply operation, and industrial temperature range (−40 °C to +85 °C).

Technical Context

This SPI flash implements JEDEC-standard Serial Flash Discoverable Parameters (SFDP) for automatic configuration and supports command-set compatibility with prior S25FL-K families while introducing volatile/non-volatile configuration registers and variable dummy-cycle latency for optimized timing across clock rates.

The device uses 90 nm floating gate technology and integrates three 256-byte one-time-programmable (OTP) security registers, hardware write protection (WP#), hold functionality (HOLD#), and top/bottom block protection ranging from 4 kB to full memory - all controllable via software commands or dedicated input pins.

Key Specifications

Parameter	Value and Actual Design Meaning
Memory Density	16 Mbit (2 Mbyte) - sufficient for boot code, firmware images, and parameter tables in space-constrained microcontroller systems.
Interface	SPI Multi-I/O (x1/x2/x4) - reduces pin count vs parallel NOR while enabling 54 MB/s quad-read throughput.
Read Speed	Quad Read at 108 MHz - 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 disturbing adjacent application code.
Endurance & Retention	100K program-erase cycles / 20-year data retention - validated for long-life industrial deployments with infrequent field updates.
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 2.7 V.
Temperature Range	−40 °C to +85 °C (Industrial) - qualified for use in motor control units, PLCs, and automotive body electronics.

Pinout & Package

Package: 8-lead SOIC (208 mil), package code SOC008 - surface-mount, RoHS-compliant, JEDEC-standard footprint suitable for automated assembly and thermal cycling reliability.

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 valid transaction.
SCK	Serial Clock Input	Provides timing reference for all SPI transfers; supports modes 0 and 3 (CPOL/CPHA); max 108 MHz.
IO0 (SI)	Serial Data Input / I/O	Primary data input during write/program; bidirectional in Dual/Quad modes; functions as SI in Single I/O mode.
IO1 (SO)	Serial Data Output / I/O	Primary data output during read; bidirectional in Dual/Quad modes; functions as SO in Single I/O mode.
IO2 (WP#)	Write Protect Input	Hardware-level protection: low = enable write/erase lock; overrides software protection when asserted.
IO3 (HOLD#)	Hold Input	Suspends ongoing command mid-execution (e.g., during read); resumes on deassertion without reinitializing CS#.
VCC	Power Supply	Single 2.7–3.6 V supply for core and I/O; no separate VIO required - simplifies power design.
VSS	Ground	Signal and power return path; requires low-impedance connection to minimize noise coupling into SPI signals.

Key Features

Feature	Design Value
Execute-In-Place (XIP) Support	Enables direct CPU instruction fetch from flash via Continuous and Wrapped Read modes - eliminates RAM copy overhead and reduces BOM cost.
Program/Erase Suspend & Resume	Allows interrupting long erase operations (e.g., 500 ms 64-kB block erase) to service higher-priority reads - critical for real-time responsiveness.
Three 256-byte OTP Security Registers	Stores immutable keys, calibration data, or device-specific identifiers - protected by lock-down until power cycle and software/hardware write disable.
JEDEC SFDP Compliance	Provides standardized, self-describing parameter table accessible via READ SFDP command - enables automatic driver initialization without hard-coded timing values.
Variable Dummy Cycle Latency	Configurable initial wait states per read command - balances high-speed access (low latency) vs. maximum clock rate (higher latency) for system-level timing closure.

Applications

IC Role / Device Role / Timing Role: Primary SPI flash for MCU boot code execution and GUI asset streaming via Quad Read mode.

Use Value: 54 MB/s quad-read throughput meets <100 ms boot time target; 20-year retention guarantees lifetime calibration data integrity; AEC-Q100 Grade 3 qualification confirmed.

Medical Diagnostic Device Parameter Archive

Smart Energy Meter Firmware Vault

Use Scenario: Archiving calibration coefficients, sensor compensation tables, and regulatory audit logs in portable ultrasound and ECG analyzers subject to IEC 62304.

IC Role / Device Role / Timing Role: Secure, long-retention non-volatile storage with hardware-enforced write lock during normal operation.

Use Value: Three OTP registers store unique device IDs and factory calibration; top/bottom block protection prevents accidental overwrite of safety-critical parameters.

Use Value: 0.002 mA deep-power-down extends backup battery life beyond 10 years; 100K endurance supports 10+ annual firmware updates over 20-year meter lifespan.

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
S25FL064L0XMFIR10	64 Mbit density, 133 MHz quad-read, 1.8 V / 3.0 V dual supply, enhanced SFDP v1.6, 200K endurance	Supports larger firmware images and faster boot; requires voltage translation if interfacing with 3.3 V-only hosts	Select for new designs needing higher density, longer lifecycle, or dual-voltage flexibility - direct migration path per Cypress documentation.
MX25L1606EM2I-12G	16 Mbit, 85 MHz max quad-read, 2.7–3.6 V, no OTP registers, no HOLD#/WP# dual-function I/O, legacy SFDP v1.0	Lacks security features and suspend/resume; simpler command set but no variable latency or industrial-plus temp support	Consider only for cost-sensitive, non-security applications where Cypress migration is not mandated and lower clock rate is acceptable.

Compared with S25FL116K0XMFIS10, S25FL064L0XMFIR10 offers higher density and endurance for future-proofing, while MX25L1606EM2I-12G trades security and advanced timing control for lower unit cost - both require PCB layout review due to differing pinouts and voltage requirements.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) designs high-performance, reliable non-volatile memory and programmable system-on-chip solutions for industrial, automotive, and consumer applications.

The S25FL1-K family was engineered to deliver SPI NOR flash with enhanced XIP performance, security, and temperature resilience for embedded systems transitioning from parallel NOR - specifically targeting code storage in resource-constrained microcontrollers.

FAQ

Is S25FL116K0XMFIS10 still recommended for new designs?

No - Cypress explicitly states this part is "Not Recommended for New Design" and recommends migrating to S25FL064L. However, Aetrix Electronics maintains active inventory and supply chain support for legacy industrial and automotive programs requiring exact form-fit-function replacement and long-term continuity.

What package does S25FL116K0XMFIS10 use, and is it RoHS-compliant?

S25FL116K0XMFIS10 uses an 8-lead SOIC (208 mil) package, marked as SOC008 in Cypress documentation. It is RoHS-compliant, lead-free, and qualified to JEDEC J-STD-020 moisture sensitivity level 3, with standard reflow profile compatibility for automated SMT assembly.

Does this device support Quad SPI mode with WP# and HOLD# disabled?

Yes - when Quad I/O mode is enabled via Status Register bit 6 (QE), the WP# and HOLD# pins are reassigned as IO2 and IO3 for quad data transfer. This is mandatory per JEDEC JESD216B; hardware write protection and hold functionality are unavailable in QIO mode.

How is security implemented in S25FL116K0XMFIS10?

Security includes three 256-byte OTP registers with lock-down protection, software/hardware write enable/disable, top/bottom block protection (configurable from 4 kB to full array), and 8-byte unique ID. All protections are enforced at silicon level - no external crypto co-processor required for basic device authentication or firmware integrity.
