Infineon Technologies S25FL116K0XMFN013

Overview

S25FL116K0XMFN013 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 up to 108 MHz and 54 MB/s continuous data transfer, uniform 4-kB sector and 64-kB block erase, and 100K program-erase cycles - deployed in embedded boot code storage and firmware update applications.

For engineers reviewing the S25FL116K0XMFN013 datasheet, S25FL116K0XMFN013 pinout, S25FL116K0XMFN013 application, or S25FL116K0XMFN013 equivalent, key selection criteria include SPI quad I/O timing compliance, industrial temperature support (−40 °C to +85 °C), SOIC-8 (150 mil) package compatibility, and security register OTP protection for firmware integrity.

Technical Context

This device implements JEDEC-standard SPI command set with modes 0 and 3 clock polarity/phase support, enabling interoperability with standard microcontroller SPI peripherals. It integrates Serial Flash Discoverable Parameters (SFDP) for automatic configuration and supports Execute-In-Place (XIP) via Continuous and Wrapped Read modes to reduce cache miss latency.

The memory uses 90 nm floating gate technology and operates across 2.7–3.6 V supply, with hardware write protection (WP#) and hold (HOLD#) inputs, plus software-controlled lock-down and non-volatile status register bits for flexible data protection schemes.

Manufacturer

Cypress Semiconductor (now part of Infineon Technologies) is a fabless semiconductor company specializing in microcontrollers, connectivity solutions, and non-volatile memory for embedded systems.

The S25FL1-K family was designed for high-reliability, SPI-based code storage in resource-constrained industrial and automotive applications - emphasizing XIP performance, security, and long-term data retention over raw density.

FAQ

Is S25FL116K0XMFN013 recommended for new designs?

No. Cypress explicitly states this part is "Not Recommended for New Design" and recommends migrating to the S25FL064L family. It remains available for legacy support and existing production, but lacks roadmap extension, newer process node benefits, and updated SFDP compliance. Designers initiating new projects should evaluate S25FL064L or Infineon's current-generation Semper™ NOR flash.

What is the function of the HOLD# and WP# pins in Quad I/O mode?

In Quad I/O (QIO) mode, both HOLD# and WP# functions are disabled and repurposed as additional data I/O lines (IO2 and IO3). This is explicitly defined in the datasheet: QIO activation disables hardware write protection and suspend capability. To retain WP#/HOLD# functionality, designers must operate in SIO or DIO mode only - a trade-off between speed and feature availability.

Does S25FL116K0XMFN013 support Execute-In-Place (XIP) reliably?

Yes. The device supports XIP via Continuous Read and Wrapped Read modes, with ≤8-clock access latency and deterministic 108 MHz Quad Read timing. Its 54 MB/s throughput exceeds typical x8 parallel NOR speeds, and SFDP enables automatic driver configuration. However, XIP stability requires proper PCB layout (controlled impedance, termination), stable VCC, and correct dummy cycle setup per operating frequency - not inherent to the device alone.

How is security implemented in S25FL116K0XMFN013?

Security includes three 256-byte OTP security registers, non-volatile status register bits controlling protection modes, software command locks, hardware WP# input, and lock-down until power cycle. Unique 8-byte ID enables device authentication. Unlike later families, it lacks AES encryption or secure boot assist - security is focused on preventing unauthorized read/write of calibration or firmware segments, not end-to-end encrypted firmware delivery.
