Infineon Technologies S25FL116K0XNFB013

Overview

S25FL116K0XNFB013 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 delivering up to 54 MB/s continuous data transfer. It features uniform 4-kB sector and 64-kB block erase, 100K program-erase cycles, 20-year data retention, and hardware/software write protection. Used in embedded boot code storage, firmware update storage, and XIP-capable microcontroller systems.

For engineers reviewing the S25FL116K0XNFB013 datasheet, S25FL116K0XNFB013 pinout, S25FL116K0XNFB013 application, or S25FL116K0XNFB013 equivalent, key selection considerations include SPI quad I/O timing compliance, industrial temperature support (−40 °C to +105 °C), SOIC-8 (208 mil) package compatibility, and migration path to S25FL064L for new designs.

Technical Context

The S25FL116K0XNFB013 implements a 90 nm floating gate architecture with JEDEC-standard SFDP (JESD216B) for discoverable parameters and supports SPI clock modes 0 and 3. Its command set includes Quad Read (06h/0Bh), Fast Read Dual Output (3Bh), and Page Program (02h), with full suspend/resume capability for both program and erase operations.

It integrates three 256-byte 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 operating across 2.6 V–3.6 V supply and −40 °C to +105 °C industrial-plus temperature range.

FAQ

Is S25FL116K0XNFB013 still 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 S25FL116K0XNFB013 remains available for legacy production and repair, new projects should adopt S25FL064L for guaranteed long-term supply, enhanced performance, and updated feature support including SFDP v1.6.

What package does S25FL116K0XNFB013 use, and is it pin-compatible with other S25FL1-K variants?

S25FL116K0XNFB013 uses an 8-lead SOIC package with 208 mil body width (footprint code SOC008). It shares identical pinout and signal definitions with S25FL132K and S25FL164K in the same SOIC-8 variant, enabling direct PCB reuse across densities - though firmware and timing parameters must be verified per density-specific datasheet sections.

Does S25FL116K0XNFB013 support Execute-In-Place (XIP) reliably?

Yes. It supports efficient XIP via Continuous Read Mode (low overhead per access) and Wrapped Read Mode (cache-line fill in one command), combined with 108 MHz Quad Read delivering 54 MB/s - sufficient to feed ARM Cortex-M7 or RISC-V cores without stalling. XIP stability is validated across −40 °C to +105 °C with proper PCB layout and VCC decoupling per datasheet Section 4.6.

How is data protection implemented on S25FL116K0XNFB013?

Data protection combines hardware (WP# and HOLD# pins), software (Status Register bits BP0–BP3, SEC, TB), and OTP-based methods. Three 256-byte security registers are permanently locked after programming; top/bottom block protection covers 4 kB to full array; lock-down mode prevents status register changes until power cycle - all operating within the 2.6–3.6 V supply range.
