Product details
Overview
S25FL164K0XNFIQ13 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) and 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 S25FL164K0XNFIQ13 datasheet, S25FL164K0XNFIQ13 pinout, S25FL164K0XNFIQ13 application, or S25FL164K0XNFIQ13 equivalent, key selection criteria include quad-speed read performance, hardware/software write protection flexibility, SFDP compliance, temperature-grade validation, and migration path awareness due to its Not Recommended for New Design status.
Technical Context
This SPI flash implements JEDEC-standard Serial Flash Discoverable Parameters (SFDP) v1.5, enabling host systems to auto-configure read latency, dummy cycles, and command sets without hard-coded initialization. Its 90 nm floating gate process supports dual/quad I/O protocols using shared IO0–IO3 pins, with WP# and HOLD# functional only in single/dual mode - disabled when Quad I/O is active.
The device uses a unified address space with configurable protection granularity: top/bottom block protection ranges from 4 kB to full memory, enforced via non-volatile status register bits, software commands, and hardware input signals (WP#, HOLD#). Security registers are one-time programmable and support pointer-based protection for S25FL132K/S25FL164K variants.

FAQ
Is S25FL164K0XNFIQ13 still in production?
No - Cypress officially retired the S25FL1-K family and designated it "Not Recommended for New Design" as of May 2017. Aetrix Electronics maintains limited legacy inventory for existing production continuity, with full traceability and documented lot history. No new wafer starts are planned, and long-term availability depends on remaining channel stock.
What package does S25FL164K0XNFIQ13 use?
S25FL164K0XNFIQ13 uses an 8-lead SOIC package with 208-mil width (JEDEC MS-012AA), marked as SOC008. Pin pitch is 1.27 mm, body dimensions are 5.3 mm × 5.3 mm × 1.75 mm, and it is RoHS-compliant with matte tin lead finish. This package is distinct from the 16-lead SOIC option also listed for S25FL164K.
Does this device support Quad Enable (QE) bit configuration?
Yes - the Quad Enable (QE) bit resides in Status Register-2 (SR2, bit 1) and must be set to '1' to activate Quad I/O mode. It is non-volatile and persists across power cycles. QE can be set via Write Status Register (01h) command after clearing Write Enable Latch (06h), and is verified using Read Status Register-2 (35h).
Can S25FL164K0XNFIQ13 be used in automotive applications?
Yes - it is qualified for AEC-Q100 Grade 2 (–40 °C to +105 °C) and Grade 3 (–40 °C to +85 °C), with full reliability test reports available. However, Infineon recommends migrating to S25FL-L family for new automotive designs due to enhanced radiation tolerance and extended qualification scope in successor parts.
