Product details
Overview
S25FL116K0XMFN043 from Cypress Semiconductor is a 16-Mbit (2 Mbyte), 3.0 V serial NOR flash memory with SPI Multi-I/O interface, supporting Quad Read at 108 MHz and 54 MB/s continuous data transfer. It features uniform 4-kB sector erase, 100K program-erase cycles, 20-year data retention, and security registers with OTP protection. Used in embedded boot code storage, firmware update storage, and XIP-capable microcontroller systems.
For engineers reviewing the S25FL116K0XMFN043 datasheet, S25FL116K0XMFN043 pinout, S25FL116K0XMFN043 application, or S25FL116K0XMFN043 equivalent, key selection criteria include quad-mode read performance, industrial temperature support (−40 °C to +105 °C), hardware write protection via WP#/HOLD#, SFDP compliance, and migration path to S25FL064L for new designs.
Technical Context
This SPI flash implements JEDEC-standard Serial Flash Discoverable Parameters (SFDP) and supports four I/O modes: Single, Dual, Quad, and Continuous Read with wrapped mode for cache-line refill. Its command set is backward-compatible with prior S25FL-K families but omits legacy commands like Quad Page Program (32h) and Half-Block Erase (52h).
The device uses 90 nm floating gate technology and operates across three temperature grades: Industrial (−40 °C to +85 °C), Industrial Plus (−40 °C to +105 °C), and AEC-Q100 Grade 2 automotive. Voltage range is 2.6 V–3.6 V, with deep-power-down current of 2 µA and quad-read active current of 16 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2 Mbyte) - sufficient for boot code, firmware images, and configuration data in resource-constrained MCU systems |
| Interface | SPI Multi-I/O (x1/x2/x4) - reduces pin count vs parallel NOR while enabling 54 MB/s quad read throughput |
| Max Clock Rate | 108 MHz - enables high-speed instruction fetch for XIP without external RAM buffering |
| Erase Granularity | Uniform 4 kB sectors and 64 kB blocks - allows fine-grained firmware updates without full chip erase |
| Data Retention | 20 years minimum - ensures long-term reliability in unattended industrial deployments |
| Endurance | 100K program-erase cycles - supports field firmware upgrades over product lifetime |
| Supply Voltage | 2.6 V–3.6 V - compatible with 3.3 V logic rails and tolerant of brown-out conditions down to 2.6 V |
Pinout & Package
Package: 8-lead SOIC (208 mil), SOIC-8 wide-body (SOC008), RoHS-compliant, surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable for SPI command sequence; must be held low for entire transaction |
| SCK | Serial Clock | Input clock synchronizing all SPI transfers; supports up to 108 MHz with controlled edge rates |
| IO0 (SI) | Serial Input / Data Line 0 | Primary input for commands, addresses, and data in single/dual/quad modes |
| IO1 (SO) | Serial Output / Data Line 1 | Primary output for read data; bidirectional in dual/quad modes |
| IO2 (WP#) | Write Protect Input | Hardware lock for top/bottom block protection; active-low, overrides software protection when asserted |
| IO3 (HOLD#) | Hold Input | Suspends ongoing command mid-execution (e.g., during erase); resumes on deassertion |
| VCC | Power Supply | Single 2.6–3.6 V supply for core and I/O; no separate VIO required |
| VSS | Ground | Common reference for all signals and power; requires low-inductance PCB return path |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read Mode | Enables 54 MB/s sustained throughput - matches x16 parallel NOR bandwidth using only 6 pins |
| Execute-In-Place (XIP) | Continuous and wrapped read modes reduce instruction fetch latency - eliminates need for boot ROM copy to RAM |
| Security Registers | Three 256-byte OTP-protected regions - store cryptographic keys, calibration data, or device-specific credentials |
| Program/Erase Suspend | Allows interrupting long erase operations to service time-critical host requests - critical for real-time firmware update scenarios |
| SFDP Compliance | JEDEC JESD216B-compliant parameter table - enables automatic driver configuration without hard-coded timing values |
Applications
| Industrial HMI Boot Storage | Automotive Telematics Firmware |
|---|---|
Use Scenario: Stores boot loader and OS kernel for ARM Cortex-A based human-machine interface panels operating in factory environments. IC Role / Device Role / Timing Role: Primary non-volatile code storage with XIP capability; provides deterministic startup timing via fast read and wrapped mode.

| Medical Diagnostic Device Configuration | Network Edge Router Boot Image |
Use Scenario: Stores calibration tables, sensor profiles, and regulatory compliance settings in portable ultrasound and ECG analyzers. IC Role / Device Role / Timing Role: Non-volatile parameter storage with OTP-secured security registers for HIPAA-compliant device identity and audit logs. Use Value: Prevents unauthorized reprogramming of medical calibration data via hardware WP# assertion and lock-down until power cycle. | Use Scenario: Hosts U-Boot and Linux kernel image for MIPS-based network edge routers requiring rapid failover and zero-downtime firmware rollbacks. IC Role / Device Role / Timing Role: High-reliability boot memory with 100K endurance and SFDP-driven driver auto-negotiation for multi-vendor compatibility. Use Value: Supports atomic dual-image updates with verified sector swap, reducing risk of bricking during remote ISP upgrades. |
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 |
|---|---|---|---|
| S25FL064L0XMFV001 | 64 Mbit density, 133 MHz max clock, 1.8 V/3.0 V dual supply, enhanced SFDP v1.6, 200K endurance | Supports larger firmware images and higher-speed boot in next-gen designs; not pin-compatible with S25FL116K | Select for new designs requiring extended density, lower voltage operation, or longer lifecycle support |
| MX25L1606E | 16 Mbit, 104 MHz max clock, 2.7–3.6 V, no Quad Read suspend/resume, no SFDP, 100K endurance | Limited to basic SPI read/write; lacks security registers, XIP optimization, and industrial-plus temp grade | Acceptable for cost-sensitive, non-automotive applications where advanced features are unused |
Compared with S25FL116K0XMFN043, S25FL064L offers higher density and future-proofed interfaces but requires PCB redesign, while MX25L1606E provides basic functionality at lower cost but sacrifices security, XIP efficiency, and temperature robustness.

FAQ
Is S25FL116K0XMFN043 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and recommends migrating to S25FL064L. It remains available for legacy production and repair, with full technical documentation and known supply chain channels maintained by Aetrix Electronics.
What package does S25FL116K0XMFN043 use?
S25FL116K0XMFN043 uses an 8-lead SOIC package with 208-mil body width (SOC008). Pinout matches standard SPI flash pin assignments: CS#, SCK, IO0, IO1, IO2 (WP#), IO3 (HOLD#), VCC, and VSS - confirmed per Cypress datasheet 002-00497 Rev. *H, page 29.
Does it support Execute-In-Place (XIP) reliably?
Yes. The device supports efficient XIP via Continuous Read and Wrapped Read modes, with quad-mode 108 MHz operation delivering 54 MB/s throughput. These modes minimize address setup overhead and align with cache-line boundaries, enabling direct CPU instruction fetch without intermediate RAM buffering.
How is security implemented in this flash device?
Security includes three 256-byte OTP-protected security registers, hardware WP#/HOLD# inputs, non-volatile status register protection bits, software command locks, and lock-down-until-power-cycle mode. Unique 8-byte ID per device enables secure provisioning; pointer-based protection (S25FL132K/S25FL164K only) is not present in this 16-Mbit variant.
