Product details
Overview
S25FL164K0XBHV023 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 S25FL164K0XBHV023 datasheet, S25FL164K0XBHV023 pinout, S25FL164K0XBHV023 application, or S25FL164K0XBHV023 equivalent, key selection criteria include quad-mode read throughput, sector protection granularity, security register configurability, and industrial-plus temperature compliance - all critical for automotive instrument clusters, industrial PLC firmware storage, and secure IoT edge node boot code.
Technical Context
This device implements a 90 nm floating-gate NOR architecture with JEDEC-standard SFDP support, enabling host systems to auto-discover configuration parameters. Its SPI-MIO interface supports command subsets compatible with legacy S25FL-K devices while adding volatile/non-volatile configuration options and variable dummy-cycle latency for optimized timing.
The memory array is organized as 128 × 64-kB blocks, each subdivided into sixteen 4-kB sectors. Protection is managed via top/bottom relative block locking, software/hardware write protection (WP# and status bits), and lock-down-until-power-cycle mode - all enforced by non-volatile status register bits and OTP-secured security registers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 Mbyte) - sufficient for full MCU boot image plus firmware update partition in space-constrained embedded designs |
| Read Throughput | 54 MB/s (Quad Read @ 108 MHz) - enables near-parallel-NOR XIP performance with only 6 pins |
| Erase Granularity | Uniform 4-kB sectors and 64-kB blocks - allows fine-grained firmware updates without disturbing adjacent code sections |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - validated for long-life industrial deployments requiring field firmware upgrades |
| Supply Voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and tolerant of brown-out conditions down to 2.6 V (Extended temp) |
| Temperature Range | –40 °C to +105 °C (Industrial Plus) - qualified for under-hood automotive and high-ambient industrial control environments |
| Security Features | Three 256-byte OTP security registers + 8-byte unique ID + pointer-based protection - supports secure boot key storage and device identity binding |
Pinout & Package
Package: 8-lead SOIC (208 mil), package code SOC008 per Cypress ordering nomenclature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable for command initiation; must be held low for entire command sequence including address and data phases |
| SCK | Serial Clock Input | Edge-triggered clock up to 108 MHz; phase/polarity modes 0 and 3 supported for compatibility with diverse host controllers |
| IO0 (SI) | Serial Data Input / I/O | Primary data input in Single/Dual/Quad modes; functions as SI in SIO, IO0 in DIO/QIO; bidirectional in QIO after instruction phase |
| IO1 (SO) | Serial Data Output / I/O | Primary data output in SIO/DIO; IO1 in DIO/QIO; bidirectional in QIO after instruction phase; supports continuous/wrapped read modes |
| IO2 (WP#) | Write Protect Input / I/O | Hardware-level write protection; active-low; disabled when Quad I/O mode is enabled per JEDEC JESD216B configuration |
| IO3 (HOLD#) | Hold Input / I/O | Suspends ongoing command (read/program/erase) mid-execution; resumes on deassertion; disabled in Quad I/O mode |
| VCC | Core & I/O Supply | Single 2.7–3.6 V supply powers both logic and memory array; internal regulation ensures stable core voltage across temperature |
| VSS | Ground | Common reference for all signals; requires low-impedance connection to minimize noise coupling during high-speed Quad Read bursts |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read (QIO) Mode | Enables 54 MB/s sustained read throughput using all four I/O lines, reducing instruction fetch latency vs. parallel NOR while cutting pin count by >50% |
| Program/Erase Suspend | Allows interrupting long erase (up to 500 ms) or program operations to service time-critical host requests, then resuming without data loss |
| Security Register Lock-Down | OTP-protected 768-byte region (3 × 256 B) prevents runtime modification of cryptographic keys or boot configuration, enforced until next power cycle |
| Variable Dummy Cycles | Configurable latency setting optimizes initial access time vs. maximum clock rate trade-off - critical for deterministic boot timing in safety-critical systems |
| Top/Bottom Block Protection | Flexible 4-kB to full-array protection range controlled by status register bits, enabling robust dual-bank firmware update schemes |

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 |
|---|---|---|---|
| S25FL064L0XMFI000 | Successor device with 65 nm process, 133 MHz Quad Read (66 MB/s), enhanced SFDP v1.6, and extended 200K endurance | Pin-compatible 8-pin SOIC (208 mil); supports same industrial-plus temp but adds deep power-down current <1 µA | Select for new designs requiring higher speed, lower power, and longer lifecycle support; migration path officially endorsed by Cypress |
| MX25L6433FZNI-10G | 64 Mbit SPI NOR from Macronix; 104 MHz Quad Read (52 MB/s); no OTP security registers; supports DTR mode | Same SOIC-8 package; lacks pointer-based protection and unique ID; offers faster sample availability but no AEC-Q100 qualification | Consider for cost-sensitive industrial applications where security features are handled externally and automotive qualification is not required |
Compared with S25FL164K0XBHV023, the S25FL064L delivers measurable improvements in speed, endurance, and power efficiency while maintaining footprint compatibility - making it the preferred choice for new designs. The MX25L6433F offers competitive pricing and broader distributor stock but omits critical security and automotive-grade reliability features.

FAQ
Is S25FL164K0XBHV023 still recommended for new designs?
No - Cypress explicitly states this part is "Not Recommended for New Design" and recommends migrating to the S25FL064L family. However, Aetrix maintains active inventory and supply chain support for legacy design continuity, including last-time-buy planning and cross-reference assistance for approved replacements.
What is the functional difference between WP# and software write protection?
WP# is a hardware-level active-low signal that globally disables all program/erase commands when asserted, independent of status register settings. Software protection uses non-volatile status register bits (SRWD, BP0–BP3) to lock specific memory regions - offering granular, configurable protection that persists across power cycles but requires command execution to modify.
Does S25FL164K0XBHV023 support Dual Transfer Rate (DTR) mode?
No - the device supports only Single Data Rate (SDR) SPI protocols (modes 0 and 3). DTR functionality is absent per the official datasheet; it does not implement double-data-rate clocking on SCK edges and lacks DTR-specific commands or configuration bits in the status or configuration registers.
Can HOLD# and WP# be used simultaneously with Quad I/O mode enabled?
No - when Quad I/O mode is activated (via Status Register bit QUAD = 1), the IO2 and IO3 pins are repurposed exclusively for data I/O, disabling both HOLD# and WP# functionality. Hardware protection and suspend/resume capabilities are unavailable in QIO mode and require fallback to SIO or DIO configurations.
