Product details
Overview
S25FL164K0XBHIS33 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, and 20-year data retention. Used in embedded boot code storage and XIP execution for industrial controllers and network edge devices.
For engineers reviewing the S25FL164K0XBHIS33 datasheet, S25FL164K0XBHIS33 pinout, S25FL164K0XBHIS33 application, or S25FL164K0XBHIS33 equivalent, key selection criteria include Quad I/O timing compliance, security register OTP protection, Industrial Plus (–40°C to +105°C) temperature rating, 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 Normal, Fast, Dual, and Quad Read commands. Its command set is footprint-compatible with prior S25FL-K families but omits legacy commands like Quad Page Program (32h) and Half-Block Erase (52h).
The memory uses 90 nm floating gate technology and integrates three 256-byte one-time-programmable (OTP) security registers, pointer-based block protection, and an 8-byte unique ID. It supports volatile and non-volatile configuration registers, enabling flexible initialization behavior across power cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 Mbyte) - sufficient for full firmware images and secure boot code in space-constrained embedded systems |
| Interface | SPI Multi-I/O (SIO/DIO/QIO) - reduces pin count vs parallel NOR while maintaining XIP performance up to 54 MB/s |
| Max Clock Rate | 108 MHz (Quad Read, –40°C to +105°C) - enables cache-line-aligned wrapped reads for efficient instruction fetch |
| Erase Granularity | Uniform 4 kB sectors and 64 kB blocks - allows fine-grained firmware updates without disturbing adjacent functional partitions |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - validated for long-life industrial deployments with infrequent field updates |
| 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 |
| Temperature Range | Industrial Plus (–40°C to +105°C) - qualified for under-hood automotive ECUs and industrial motor drives |
Pinout & Package
Package: 8-lead SOIC (208 mil), package code SOC008 - surface-mount, RoHS-compliant, compatible with standard reflow profiles and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable for command initiation; must be held low for entire command duration including dummy cycles |
| SCK | Serial Clock | Input clock synchronizing all SPI transfers; supports modes 0 and 3; max 108 MHz in Quad Read mode |
| IO0 (SI) | Serial Input / Data Line 0 | Primary input for instructions and address bits in SIO mode; bidirectional data line 0 in DIO/QIO modes |
| IO1 (SO) | Serial Output / Data Line 1 | Primary output for read data in SIO mode; bidirectional data line 1 in DIO/QIO modes |
| IO2 (WP#) | Write Protect / Data Line 2 | Hardware write lock when asserted low; repurposed as data line 2 in Quad I/O mode (disables WP function) |
| IO3 (HOLD#) | Hold / Data Line 3 | Pauses ongoing command at any clock cycle; repurposed as data line 3 in Quad I/O mode (disables HOLD function) |
| VCC | Power Supply | Single 2.7–3.6 V supply powering core and I/O; deep-power-down current = 2 µA |
| VSS | Ground | Signal and power ground reference; decoupling capacitor required within 10 mm of VCC pin |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read (QIO) Mode | Enables 54 MB/s sustained throughput - matches x16 parallel NOR bandwidth using only 6 pins, reducing PCB layer count |
| Program/Erase Suspend | Allows background erase to pause during high-priority read access - critical for real-time firmware update scenarios |
| Three 256-byte OTP Security Registers | Stores immutable keys, certificates, or calibration data - protected by lock-down until power cycle and software/hardware write enable |
| Serial Flash Discoverable Parameters (SFDP) | JEDEC JESD216B-compliant parameter table - enables automatic host driver configuration without hard-coded timing values |
| Variable Dummy Cycle Latency | Configurable initial latency (1–8 cycles) - balances fast startup time vs maximum clock rate for system-level timing closure |
Applications
| Industrial PLC Firmware Storage | Automotive ADAS Boot Memory |
|---|---|
|

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 family; 64 Mbit, 133 MHz Quad Read, 256 KB uniform sectors, 200K endurance, 25-year retention | Supports higher clock rates and larger erase blocks; lacks pointer-based protection but adds SFDP v1.6 | Preferred for new designs requiring extended lifecycle support and higher endurance; requires layout change due to WSON-8 (5×6 mm) package |
| MX25L6433FZNI-10G | 64 Mbit, 104 MHz Quad Read, 4 kB/64 kB erase, 100K endurance, 20-year retention; no OTP security registers | No hardware-based security registers or pointer protection; supports standard SPI only (no MIO mode switching) | Cost-sensitive industrial applications where security features are implemented in external MCU; identical SOIC-8 (208 mil) footprint enables drop-in replacement |
Compared with S25FL164K0XBHIS33, S25FL064L offers higher performance and longer lifecycle support but requires board redesign, while MX25L6433F provides pin-compatible fallback without security features-making it suitable only where host-side encryption replaces on-die OTP protection.

Manufacturer
Cypress Semiconductor (now part of Infineon Technologies) designs high-reliability non-volatile memory and microcontroller solutions for industrial, automotive, and communications infrastructure markets.
The S25FL1-K family was engineered to deliver SPI NOR flash with enhanced security, XIP performance, and temperature resilience for mission-critical embedded boot and firmware storage applications.
FAQ
Is S25FL164K0XBHIS33 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and designates S25FL064L as the factory-recommended migration path. While fully functional and supported for existing production, new projects should adopt the S25FL-L family for long-term availability, improved specs, and active technical support.
What does the 'X' in S25FL164K0XBHIS33 indicate?
The 'X' denotes Industrial Plus temperature grade (–40°C to +105°C), confirmed in the datasheet's ordering information table. The 'BHI' suffix specifies 8-lead SOIC (208 mil) package with lead-free, halogen-free, and RoHS-compliant construction per IPC/JEDEC J-STD-020 moisture sensitivity level 3.
Can S25FL164K0XBHIS33 operate in Quad I/O mode while retaining WP# and HOLD# functionality?
No. When Quad I/O mode is enabled, IO2 and IO3 are reassigned as data lines, disabling both WP# and HOLD# hardware control functions. Protection must then rely solely on software commands (e.g., Write Enable Lock, Block Protection bits) or external logic.
How is the 8-byte Unique ID accessed?
The 8-byte Unique ID is read using the Read Electronic Manufacturer ID and Device ID command (90h) followed by the Read Unique ID command (4Bh), though the latter is explicitly listed as "not supported" for S25FL1-K in the migration notes. Instead, the device implements JEDEC JESD216B SFDP table (at address 000000h) which contains manufacturer and density identifiers-but not a globally unique serial number.
