Infineon Technologies S25FL116K0XMFIS13

Overview

S25FL116K0XMFIS13 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 is packaged in 8-lead SOIC (150 mil).

For engineers reviewing the S25FL116K0XMFIS13 datasheet, S25FL116K0XMFIS13 pinout, S25FL116K0XMFIS13 application, or S25FL116K0XMFIS13 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 command subsets compatible with prior S25FL-K families. Its 90 nm floating gate technology enables single-supply operation from 2.7 V to 3.6 V with programmable latency for optimized read timing across temperature ranges.

The device integrates three 256-byte one-time-programmable (OTP) security registers, 8-byte unique ID, and flexible protection schemes including top/bottom block lock, software command lock-down, and hardware WP#/HOLD# inputs - all configurable via non-volatile and volatile status registers.

FAQ

Is S25FL116K0XMFIS13 recommended for new designs?

No - Cypress explicitly states this part is "Not Recommended for New Design" and designates S25FL064L as the factory-recommended migration path. While fully functional and supported for existing production, new projects should adopt the S25FL-L family for long-term supply assurance, enhanced features, and updated qualification.

What package does S25FL116K0XMFIS13 use?

S25FL116K0XMFIS13 uses an 8-lead SOIC package with 150 mil body width (SOA008), lead pitch of 1.27 mm, and RoHS-compliant matte tin finish. This package is compatible with standard PCB assembly processes and offers thermal performance suitable for industrial ambient temperatures.

Does this device support Execute-In-Place (XIP)?

Yes - S25FL116K0XMFIS13 supports efficient XIP via Continuous Read and Wrapped Read modes. These modes minimize command overhead and enable cache-line-aligned burst reads, allowing microcontrollers to execute code directly from flash with latency comparable to RAM access in optimized configurations.

How is write protection implemented on this flash?

Write protection is implemented through multiple layers: hardware WP# pin assertion, software commands (Write Enable/Disable, Write Status Register), non-volatile status register bits (BP0–BP2), and OTP-locked security registers. Protection can be configured for top/bottom memory regions down to 4 kB granularity, with lock-down until power cycle for highest security.
