It operates across –40 °C to +105 °C (Industrial Plus), features three 256-byte OTP security registers, 8-byte unique ID, and Execute-In-Place (XIP) capability for embedded code storage in microcontroller boot applications.
For engineers reviewing the S25FL164K0XMFA011 datasheet, S25FL164K0XMFA011 pinout, S25FL164K0XMFA011 application, or S25FL164K0XMFA011 equivalent, key selection criteria include quad-mode read throughput, hardware write protection via WP#/HOLD#, SFDP compliance, security register configurability, and migration path to S25FL064L for new designs.
Technical Context
This device implements a 90 nm floating-gate NOR architecture with SPI-MIO support for Single/Dual/Quad I/O protocols using only four to six pins (CS#, SCK, IO0–IO3). It uses JEDEC-standard command set with SFDP v1.5 (JESD216B) for parameter discovery and supports volatile/non-volatile configuration register settings.
Memory organization comprises 128 uniform 64 kB blocks (8,192 × 4 kB sectors), with independent suspend/resume for program and erase operations. Security logic includes pointer-based block protection, top/bottom relative range locking, and lock-down-until-power-cycle mode enforced by non-volatile status bits and hardware inputs.

FAQ
Is S25FL164K0XMFA011 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and identifies 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, improved performance, and updated feature sets including enhanced SFDP and thermal robustness.
What package does S25FL164K0XMFA011 use, and is it RoHS-compliant?
S25FL164K0XMFA011 uses an 8-lead SOIC package with 208 mil body width (SOC008 footprint), specified in the datasheet's ordering information table. It is RoHS-compliant and lead-free, with matte tin finish on leads and符合 JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) handling requirements.
Does this device support Execute-In-Place (XIP) reliably across temperature ranges?
Yes. The device supports continuous and wrapped read modes optimized for XIP, with guaranteed 108 MHz Quad Read operation from –40 °C to +105 °C. Its 54 MB/s throughput exceeds typical Cortex-M instruction fetch bandwidth, and the 8-clock overhead in continuous read mode ensures deterministic cache-line refill latency critical for real-time execution.
How is security implemented, and can the OTP registers be reprogrammed?
Security relies on three 256-byte OTP registers (locked permanently after first programming), 8-byte unique ID, non-volatile status register bits, and hardware WP#/HOLD# inputs. Once programmed, OTP contents cannot be altered - they are used for cryptographic key storage, device identity binding, and secure boot signature verification in certified systems.
