Product details
Overview
S25FL164K0XMFA013 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 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 and XIP execution for industrial microcontrollers.
For engineers reviewing the S25FL164K0XMFA013 datasheet, S25FL164K0XMFA013 pinout, S25FL164K0XMFA013 application, or S25FL164K0XMFA013 equivalent, key selection criteria include quad I/O timing compliance, security register OTP configuration, industrial-plus temperature support (−40 °C to +105 °C), and migration path to S25FL064L.
Technical Context
This device implements JEDEC-standard SPI Multi-I/O (MIO) with configurable clock polarity/phase (modes 0 and 3), supporting Single, Dual, and Quad I/O protocols using shared IO0–IO3 pins. QIO mode disables WP# and HOLD# functions, requiring software-based protection when enabled.
The memory uses 90 nm floating gate technology and integrates Serial Flash Discoverable Parameters (SFDP) per JEDEC JESD216B for automatic configuration. Its status register controls volatile/non-volatile protection modes, and it includes three 256-byte OTP security registers with pointer-based block protection range control.
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 with 65 nm process, higher 133 MHz Quad Read speed (66.5 MB/s), and enhanced ECC support | Required for new designs; supports extended voltage range (1.7–3.6 V) and wider temperature grades including AEC-Q100 Grade 1 | Select for all new designs requiring lifecycle assurance and improved performance; migration requires minor timing and command set adjustments |
| MX25L6433F | 64 Mbit SPI NOR from Macronix; supports 133 MHz Quad Read but lacks SFDP and OTP security registers | Lower-cost alternative where cryptographic key storage and auto-configuration are not required | Use only in cost-sensitive consumer applications without security or long-term industrial support requirements |
Compared with S25FL064L, this part offers legacy footprint compatibility but lacks ECC and extended voltage support; versus MX25L6433F, it provides stronger security and JEDEC-standard configurability at higher unit cost and end-of-life risk.

FAQ
Is S25FL164K0XMFA013 still in production and supported?
Yes, S25FL164K0XMFA013 remains in production and supported by Infineon for existing designs, though it is marked "Not Recommended for New Design" per datasheet Rev. *H. Aetrix maintains active inventory and provides full traceability, with documented last-time-buy windows and cross-reference guidance for migration to S25FL064L.
What package does S25FL164K0XMFA013 use, and is it RoHS compliant?
S25FL164K0XMFA013 uses an 8-lead SOIC package with 208-mil body width (SOC008 footprint). It is RoHS-compliant, lead-free, and qualified for reflow soldering per IPC/JEDEC J-STD-020. The package supports standard pick-and-place and automated optical inspection workflows.
Does this device support Execute-in-Place (XIP) operation, and what latency is required?
Yes, S25FL164K0XMFA013 supports efficient XIP via Continuous Read Mode and Wrapped Read Mode. Quad Read commands require programmable dummy cycles (configurable via status register) - typical latency is 6 cycles at 108 MHz for optimal timing margin in industrial temperature ranges.
Can the security registers be reprogrammed after initial programming?
No - the three 256-byte security registers are One-Time Programmable (OTP). Once written, individual bits cannot be cleared or rewritten. Programming is performed via standard SPI commands (e.g., Write Enable + Program Security Register), and verification is supported through dedicated read commands.
