Product details
Overview
S25FL164K0XNFI013 from Cypress Semiconductor is a 64-Mbit (8 Mbyte), 3.0 V serial NOR flash memory with SPI Multi-I/O interface, supporting Quad Read at 108 MHz (54 MB/s), uniform 4 kB sector and 64 kB block erase, and 100K program-erase cycles. 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 S25FL164K0XNFI013 datasheet, S25FL164K0XNFI013 pinout, S25FL164K0XNFI013 application, or S25FL164K0XNFI013 equivalent, key selection considerations include quad-speed read performance, hardware/software write protection modes, SFDP compliance, temperature-grade validation, and migration path to S25FL064L for new designs.
Technical Context
This device implements a JEDEC-standard SPI interface with configurable clock polarity/phase (modes 0 and 3), supporting Single/Dual/Quad I/O protocols using shared IO0–IO3 pins. Its command set includes suspend/resume for program and erase operations, and pointer-based block protection exclusive to S25FL132K/S25FL164K variants.
The memory uses 90 nm floating gate technology, single 2.7–3.6 V supply, and integrates Serial Flash Discoverable Parameters (SFDP v1.5 per JESD216B) for host auto-configuration. Security architecture includes volatile/non-volatile status register control, lock-down until power cycle, and hardware WP#/HOLD# inputs disabled when Quad I/O is active.
Key Specifications

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 | Successor family; 64 Mbit, 133 MHz Quad Read (66.5 MB/s), 65 nm process, enhanced SFDP v1.6 | Supports newer host controllers requiring extended parameter tables and faster timing margins | Select for new designs requiring extended lifecycle support and higher performance headroom |
| MX25L6433F | 64 Mbit, 133 MHz Quad Read, 1.65–3.6 V supply, no Industrial Plus temp grade (max +85°C) | Lacks AEC-Q100 qualification and pointer-based protection; lower security feature set | Acceptable for cost-sensitive commercial applications where extended temperature and advanced security are not required |
Compared with S25FL164K0XNFI013, S25FL064L offers higher speed and longer manufacturer support, while MX25L6433F trades security and temperature range for broader voltage operation and lower unit cost - choice depends on certification, longevity, and performance requirements.
Availability
S25FL164K0XNFI013 is available at Aetrix Electronics and suitable for industrial PLC firmware storage, automotive ADAS boot memory, and medical imaging system configuration requiring stable component supply despite end-of-life status.

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, code-execution-capable SPI flash in space-constrained industrial and automotive applications - emphasizing XIP performance, security, and extended temperature operation before migration to the S25FL-L series.
FAQ
Is S25FL164K0XNFI013 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 fully functional and supported for existing production, new projects should adopt the S25FL-L family for guaranteed long-term availability, enhanced performance, and updated JEDEC compliance.
What package does S25FL164K0XNFI013 use, and is it pin-compatible with other S25FL1-K variants?
S25FL164K0XNFI013 uses an 8-lead SOIC (208 mil) package (SOC008). It shares footprint compatibility with S25FL132K in the same package but differs from S25FL116K (which uses 150-mil SOIC). All S25FL1-K devices maintain command-set and pinout compatibility within their respective package types, enabling drop-in replacement where density and temperature grade align.
Does S25FL164K0XNFI013 support Quad I/O mode, and what happens to WP# and HOLD# in that mode?
Yes, it supports Quad I/O mode with up to 108 MHz clock rate and 54 MB/s throughput. When Quad I/O is enabled, the WP# and HOLD# functions are disabled - their pins (IO2 and IO3) become dedicated data lines. Hardware write protection must then be managed exclusively via software commands and non-volatile status register bits.
How is security implemented in S25FL164K0XNFI013, and what distinguishes it from earlier FL-K devices?
It implements three 256-byte OTP security registers, 8-byte unique ID, pointer-based block protection (S25FL132K/S25FL164K only), and lock-down until power cycle. Unlike S25FL-K, it adds volatile configuration for latency tuning and Industrial Plus temperature support, while retaining identical OTP size and format - making it a direct upgrade for security-critical legacy designs needing extended temp range.
