Product details
Overview
S25FL164K0XNFV011 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 and 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 and XIP applications requiring compact, low-pin-count non-volatile memory.
For engineers reviewing the S25FL164K0XNFV011 datasheet, S25FL164K0XNFV011 pinout, S25FL164K0XNFV011 application, or S25FL164K0XNFV011 equivalent, key selection factors include Quad I/O read performance, industrial-plus temperature support (−40 °C to +105 °C), security register OTP protection, and migration path to S25FL064L for new designs.
Technical Context
This SPI flash operates in standard, dual, and quad I/O modes using a 4–6 signal interface (CS#, SCK, IO0–IO3), with WP# and HOLD# functional only in single/dual mode. Its 90 nm floating gate technology enables reliable operation across 2.6 V–3.6 V supply and −40 °C to +105 °C industrial-plus range.
The device implements Serial Flash Discoverable Parameters (SFDP) per JEDEC JESD216B, supports Execute-In-Place (XIP) via continuous/wrapped read modes, and includes three 256-byte one-time-programmable security registers with pointer-based protection - exclusive to S25FL132K and S25FL164K variants.
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, 1.8 V/3.0 V dual supply, enhanced SFDP v1.6 | Supports newer controllers with SFDP v1.6 parsing; adds octal DTR mode in higher-density variants | Select for new designs requiring extended lifecycle support and improved power efficiency |
| MX25L6433F | 64 Mbit, 104 MHz Quad Read, 2.7–3.6 V, no pointer-based protection or Industrial Plus temp grade | Lacks OTP security registers and −40 °C to +105 °C qualification; lower cost for commercial-temp applications | Acceptable for cost-sensitive, non-safety-critical consumer designs with standard industrial temp range |
Compared with S25FL164K0XNFV011, S25FL064L offers higher clock rate and longer-term availability but requires board-level voltage redesign for 1.8 V I/O; MX25L6433F provides pin-compatible drop-in replacement only for basic read/write functions, omitting security and extended temperature capabilities.

FAQ
Is S25FL164K0XNFV011 still recommended for new designs?
No. Cypress explicitly designates this part as "Not Recommended for New Design" and recommends migrating to the S25FL064L family. While fully functional and supported for existing production, it has been retired from active development and long-term supply planning. New projects should use S25FL064L to ensure roadmap alignment and extended availability.
What package does S25FL164K0XNFV011 use?
S25FL164K0XNFV011 uses a 24-ball BGA package measuring 6 mm × 8 mm, with ball pitch of 0.8 mm and footprint compatibility with FAB024 and FAC024 land patterns. This package supports high-density PCB layouts and thermal performance suitable for industrial-plus temperature operation.
Does this device support Quad I/O mode with hardware write protection enabled?
No. When Quad I/O mode is active, the WP# (IO2) and HOLD# (IO3) pins are repurposed as data lines and hardware write protection is disabled. Software-based protection (via Status Register bits) remains available, but physical pin-level locking is inactive in Quad mode.
Can S25FL164K0XNFV011 be used in automotive applications?
Yes - it is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C) and Grade 3 (−40 °C to +85 °C), making it suitable for infotainment, telematics, and body control modules. However, Infineon's current automotive recommendation is S25FL064L, which offers updated qualification and extended support.
