Product details
Overview
S25FL116K0XMFB041 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 and automotive systems.
For engineers reviewing the S25FL116K0XMFB041 datasheet, S25FL116K0XMFB041 pinout, S25FL116K0XMFB041 application, or S25FL116K0XMFB041 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 hardware/software write protection with security registers.
Technical Context
This SPI flash implements JEDEC-standard Serial Flash Discoverable Parameters (SFDP) and supports SPI clock modes 0 and 3. It uses 90 nm floating gate technology and delivers XIP-optimized continuous/wrapped read modes with configurable dummy cycles for latency tuning.
The device integrates three 256-byte one-time-programmable (OTP) security registers, top/bottom block protection, 8-byte unique ID, and dual protection mechanisms-software command lock and hardware WP#/HOLD# inputs-with Quad I/O disabling WP#/HOLD# when active.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2 Mbyte) - sufficient for boot code, firmware images, and configuration data in space-constrained MCU systems. |
| Read Throughput (Quad) | 54 MB/s at 108 MHz - matches parallel NOR performance with only 6 pins, enabling high-speed XIP in resource-limited designs. |
| Erase Granularity | Uniform 4 kB sectors and 64 kB blocks - allows fine-grained firmware updates without disturbing adjacent code or data sections. |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - validated for long-life industrial control and automotive ECUs requiring field reliability. |
| 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 +105 °C (Industrial Plus) - qualified for under-hood automotive and high-ambient industrial environments. |
| Security Features | Three 256-byte OTP registers + software/hardware write protection - enables secure boot key storage and immutable configuration lockdown. |
Pinout & Package
Package: 8-lead SOIC (208 mil), package code SOC008 - surface-mount, RoHS-compliant, industry-standard footprint with 1.27 mm pitch.
| 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 communication. |
| SCK | Serial Clock Input | Master-generated clock driving all SPI transfers; supports up to 108 MHz for Quad Read mode timing compliance. |
| IO0 (SI) | Serial Data Input / I/O | Primary data input in Single/Dual/Quad modes; functions as SI in SIO, IO0 in DIO/QIO; bidirectional in QIO after command phase. |
| IO1 (SO) | Serial Data Output / I/O | Primary data output in SIO/DIO; IO1 in DIO/QIO; bidirectional in QIO; carries status/data during read commands. |
| IO2 (WP#) | Write Protect Input / I/O | Hardware-level write lock; low = protection enabled; disabled when Quad I/O mode is active per JEDEC SFDP configuration. |
| IO3 (HOLD#) | Hold Input / I/O | Suspends ongoing command mid-execution (e.g., during erase); low = hold asserted; disabled in Quad I/O mode. |
| VCC | Power Supply | Single 2.7–3.6 V supply powering core and I/O; internal regulation ensures stable operation across voltage range. |
| VSS | Ground | Reference return path for all signals and power; requires low-impedance PCB connection to minimize noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read Mode | 54 MB/s sustained throughput with 4-bit data bus - eliminates need for wider parallel interfaces while maintaining XIP performance. |
| Program/Erase Suspend | Interrupts long erase (e.g., 64 kB block) or program operations to service higher-priority host requests - critical for real-time firmware updates. |
| Wrapped Read Mode | Optimizes cache-line refill by reading first byte on demand, then streaming full line in one command - reduces instruction fetch latency in XIP execution. |
| JEDEC SFDP Support | Self-describing parameter table accessible via standard command (5Ah) - enables automatic driver configuration without hard-coded timing constants. |
| OTP Security Registers | Three independent 256-byte regions with permanent lock bits - stores cryptographic keys, calibration data, or device-specific credentials immune to reprogramming. |
Applications
| Industrial PLC Firmware Storage | Automotive Instrument Cluster Boot Memory |
|---|---|
|
Use Scenario: Storing boot loader and real-time control firmware in programmable logic controllers operating continuously in factory environments with ambient temperatures up to +105 °C. IC Role / Device Role / Timing Role: Non-volatile code storage with Execute-In-Place (XIP) support, enabling direct CPU execution without RAM shadowing to reduce BOM cost and boot time. Use Value: 100K endurance and 20-year retention ensure firmware integrity over 15+ year product lifecycles; Quad Read delivers 54 MB/s instruction fetch to sustain deterministic task scheduling. |
Use Scenario: Holding calibrated display graphics, gauge logic, and safety-critical startup routines in automotive digital instrument clusters certified to AEC-Q100 Grade 2 (−40 °C to +105 °C). IC Role / Device Role / Timing Role: Primary boot memory mapped into MCU address space; leverages wrapped read mode for rapid cache-line fills during cluster initialization. Use Value: Hardware WP#/HOLD# inputs allow ECU-level write protection during vehicle operation; OTP registers store anti-tamper calibration signatures verified at power-on. |
| Medical Diagnostic Device Configuration | Network Edge Router Boot Image |
|
Use Scenario: Storing device-specific calibration tables, regulatory compliance parameters, and user-interface assets in portable ultrasound and ECG analyzers requiring FDA-grade data integrity. IC Role / Device Role / Timing Role: Secure configuration repository with three OTP registers protecting calibration coefficients against accidental overwrite or malicious modification. Use Value: 8-byte unique ID enables traceability per unit; 4 kB sector erase permits field updates to calibration data without affecting diagnostic algorithms stored elsewhere. |
Use Scenario: Hosting bootloader and Linux kernel image in carrier-grade edge routers where fast, reliable boot is required after power cycling or firmware rollback. IC Role / Device Role / Timing Role: High-throughput SPI flash interfaced directly to ARM Cortex-A series SoCs; Quad Read mode minimizes boot latency versus legacy parallel NOR. Use Value: 54 MB/s read bandwidth reduces boot time by >40% vs. 50 MHz single-I/O flash; SFDP auto-configuration simplifies driver porting across router SKUs. |
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 Quad Read (66.5 MB/s), 1.8 V / 3.0 V dual supply, enhanced SFDP v1.6, no HOLD#/WP# in QIO mode (same as S25FL116K). | Higher density and speed; supports newer low-voltage platforms; lacks Industrial Plus temperature grade (max +85 °C only). | Select for new designs needing >16 Mbit capacity or 1.8 V compatibility; migration path recommended by Cypress for S25FL1-K family. |
| MX25L1606E | 16 Mbit, 104 MHz Quad Read (52 MB/s), 2.7–3.6 V, no OTP security registers, no program/erase suspend, JEDEC SFDP v1.0 only. | Lower cost but no security or suspend features; suitable for non-critical consumer applications without firmware integrity requirements. | Choose only for cost-sensitive, non-secure applications where 2 MB storage suffices and suspend/resume is unnecessary. |
Compared with S25FL064L and MX25L1606E, the S25FL116K0XMFB041 uniquely combines Industrial Plus temperature rating (+105 °C), OTP-based security, and suspend/resume functionality within its 16 Mbit class - making it irreplaceable for legacy industrial and automotive designs requiring those specific capabilities.
