Product details
Overview
S25FL116K0XMFV043 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 S25FL116K0XMFV043 datasheet, S25FL116K0XMFV043 pinout, S25FL116K0XMFV043 application, or S25FL116K0XMFV043 equivalent, key selection considerations include quad-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
This SPI flash implements JEDEC-standard Serial Flash Discoverable Parameters (SFDP) and supports SPI clock modes 0 and 3. Its command set enables page programming (up to 256 bytes), program/erase suspend-resume, and flexible protection via non-volatile status register bits, OTP security registers, and hardware WP#/HOLD# pins.
The device integrates a 4-kB sector-aligned memory array with uniform erase granularity, continuous/wrapped read modes for efficient XIP, and dual/quad I/O protocols using shared IO0–IO3 pins - where Quad mode disables WP# and HOLD# functionality per JEDEC-compliant configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2 Mbyte) - fixed capacity for compact firmware storage without over-provisioning. |
| Read Throughput (Quad) | 54 MB/s at 108 MHz - matches parallel NOR performance with only 6-pin SPI interface. |
| Erase Granularity | Uniform 4 kB sectors and 64 kB blocks - enables fine-grained firmware updates and robust OTA patching. |

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, 2.7–3.6 V, supports DTR mode and deeper power-down states | Higher capacity and speed; recommended for new designs per Cypress migration notice | Select when upgrading firmware footprint or requiring >16 Mbit storage with extended feature set |
| MX25L1606E | 16 Mbit, 85 MHz Quad Read, 2.7–3.6 V, lacks SFDP, no program/erase suspend-resume | Lower cost alternative without advanced timing or suspend features | Choose for cost-sensitive applications where suspend/resume and JEDEC SFDP are not required |
Compared with S25FL116K0XMFV043, S25FL064L offers higher density and speed with full migration support, while MX25L1606E provides basic 16 Mbit functionality at lower complexity and cost - making the former ideal for design refreshes and the latter suitable for legacy-compatible cost optimization.

FAQ
Is S25FL116K0XMFV043 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 support and last-time buys, but no new design-in should use it due to obsolescence and lack of future roadmap alignment.
What package does S25FL116K0XMFV043 use?
S25FL116K0XMFV043 uses an 8-lead SOIC package with 208 mil body width (package code SOC008), pin-compatible with other members of the S25FL1-K family in that variant, and compliant with industry-standard SOIC footprints.
Does this device support Execute-In-Place (XIP)?
Yes. The S25FL116K0XMFV043 supports efficient XIP via Continuous and Wrapped Read modes, enabling microcontrollers to execute code directly from flash without loading into RAM - reducing system memory requirements and boot latency.
How is write protection implemented on this flash?
Write protection is implemented through three independent mechanisms: hardware WP# pin assertion, software commands controlling non-volatile status register bits, and OTP-locked security registers - allowing layered protection for boot code, configuration, and calibration data.
