Product details
Overview
S25FL164K0XBHV033 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, and 20-year data retention. Used for XIP code execution and firmware storage in space-constrained embedded controllers.
For engineers reviewing the S25FL164K0XBHV033 datasheet, S25FL164K0XBHV033 pinout, S25FL164K0XBHV033 application, or S25FL164K0XBHV033 equivalent, key selection factors include Quad I/O timing compliance, industrial-plus temperature support (–40 °C to +105 °C), hardware write protection via WP#/HOLD#, and SFDP-compliant configuration.
Technical Context
This device implements a 90 nm floating-gate architecture with JEDEC-standard SPI command set (modes 0 and 3), supporting Normal, Fast, Dual, and Quad Read protocols. It integrates three 256-byte OTP security registers, 8-byte unique ID, and pointer-based block protection for S25FL132K/S25FL164K variants.
It operates across 2.6 V–3.6 V supply range and supports Industrial Plus (–40 °C to +105 °C) and AEC-Q100 Grade 2 automotive qualification. Erase suspend/resume and program suspend/resume enable real-time background operations without host interruption.
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 density, 133 MHz Quad Read, 1.8 V/3.0 V dual supply, enhanced security engine | Supports newer platforms requiring lower voltage, higher speed, or advanced crypto acceleration | Select for new designs requiring extended lifecycle support and improved performance envelope |
| MX25L6433F | 64 Mbit, 104 MHz Quad Read, 2.7–3.6 V, no OTP security registers, no suspend/resume | Limited to cost-sensitive applications where security and background operation are not required | Consider only if legacy compatibility and minimal feature set suffice; lacks industrial-plus temp grade |
Compared with S25FL064L, this part offers proven industrial-plus reliability but lacks newer security and speed enhancements; compared with MX25L6433F, it delivers superior data integrity and real-time operation features at higher cost and end-of-life risk.

FAQ
Is S25FL164K0XBHV033 still recommended for new designs?
No - Cypress explicitly states this part is "Not Recommended for New Design" and recommends migration to S25FL064L. It remains available for legacy production and repair, with full technical documentation and known lifecycle status. Aetrix maintains inventory and supports continuity planning for existing programs.
What package does S25FL164K0XBHV033 use?
S25FL164K0XBHV033 uses an 8-lead SOIC package with 208-mil body width (SOC008). This is distinct from the 150-mil SOIC used in lower-density variants and differs from WSON or BGA options in the same family. Pinout and thermal characteristics match JEDEC MS-012AC standards.
Does this device support Execute-In-Place (XIP) reliably?
Yes - it supports efficient XIP via Continuous Read and Wrapped Read modes, with Quad Read delivering 54 MB/s at 108 MHz. The 8-clock overhead per access and burst-aligned cache refill minimize latency, making it suitable for direct CPU instruction fetch in ARM Cortex-M and RISC-V microcontrollers with QSPI controllers.
How is security implemented in S25FL164K0XBHV033?
Security includes three 256-byte OTP registers, top/bottom block protection with pointer-based ranges, hardware WP#/HOLD# inputs, software command locks, and lock-down-until-power-cycle mode. Unique 8-byte ID enables device authentication. All security features are validated per datasheet Rev. *H and supported across Industrial Plus and AEC-Q100 Grade 2 operating conditions.
