Product details
Overview
S25FL164K0XBHIS20 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 including OTP-secured 256-byte security registers. Used for XIP code execution and firmware storage in industrial microcontroller boot systems.
For engineers reviewing the S25FL164K0XBHIS20 datasheet, S25FL164K0XBHIS20 pinout, S25FL164K0XBHIS20 application, or S25FL164K0XBHIS20 equivalent, key selection criteria include quad-mode read bandwidth, sector protection granularity, deep power-down current (2 µA), AEC-Q100 Grade 2 qualification, and migration path to S25FL064L.
Technical Context
This SPI flash implements JEDEC JESD216B-compliant SFDP for automatic configuration discovery and supports four I/O modes: Single, Dual, Quad, and QPI. Its 90 nm floating-gate architecture enables stable operation across −40 °C to +105 °C (Industrial Plus) with single 2.7–3.6 V supply.
The device uses command-based addressing with 24-bit address space, supports program/erase suspend-resume, and integrates three 256-byte one-time-programmable security registers with pointer-based protection. WP# and HOLD# pins provide hardware-level control over write and command execution flow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 Mbyte) - sufficient for full MCU boot image + firmware + configuration data in space-constrained embedded designs |
| Read Throughput | 54 MB/s (Quad Read @ 108 MHz) - matches parallel NOR performance while using only 6 pins |
| Erase Granularity | 4 kB sectors and 64 kB blocks - enables fine-grained firmware updates without full chip erase |
| Endurance & Retention | 100K program-erase cycles / 20-year data retention - validated for long-life industrial deployments |
| 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 | −40 °C to +105 °C (Industrial Plus) - qualified for under-hood automotive and high-ambient industrial control |
| Power Consumption | 2 µA deep-power-down current - enables ultra-low standby power in battery-backed systems |
Pinout & Package
Package: 8-lead SOIC (208 mil), standardized footprint per SOC008 specification. Compatible with reflow and wave soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable for SPI command sequence; must be held low for entire transaction duration |

| IO1 (SO) | Serial Data Output / I/O1 | Primary data output in Single/Dual mode; bidirectional in Quad mode |
| IO2 (WP#) | Write Protect Input / I/O2 | Hardware lock for status register and memory array; active-low, disables write/erase when asserted |
| IO3 (HOLD#) | Command Hold Input / I/O3 | Pauses ongoing command (read/program/erase) on any clock edge; resumes after deassertion |
| VCC | Power Supply | 2.7–3.6 V core and I/O supply; decoupling capacitor required per datasheet layout guidelines |
| VSS | Ground | Signal and power return reference; requires low-impedance connection to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read Mode | Enables 54 MB/s throughput via 4-bit I/O, eliminating need for wider parallel interfaces in cost-sensitive designs |
| Program/Erase Suspend | Allows interrupting long erase operations to service time-critical reads, improving real-time system responsiveness |
| Security Registers | Three 256-byte OTP regions protect boot code integrity and device identity; accessible only via dedicated security commands |
| Variable Dummy Cycles | Configurable latency in read commands balances access speed vs. maximum clock rate for timing-critical applications |
| SFDP Compliance | JEDEC JESD216B-compliant parameter table enables automatic host initialization without hard-coded timing constants |

FAQ
Is S25FL164K0XBHIS20 still recommended for new designs?
No. Cypress explicitly states this part is "Not Recommended for New Design" and recommends migrating to S25FL064L. It remains available for legacy production and repair, with full datasheet support and known parametric behavior, but no future revisions or extended lifecycle guarantees.
What package does S25FL164K0XBHIS20 use?
S25FL164K0XBHIS20 uses an 8-lead SOIC package with 208 mil body width (SOC008 footprint). Pin count and spacing comply with JEDEC MS-012, and the package is RoHS-compliant with matte tin lead finish.
Does this device support Quad SPI mode with WP# and HOLD# disabled?
Yes. When Quad I/O mode is enabled (via Status Register bit 6), the WP# and HOLD# pins are reassigned as IO2 and IO3, disabling their hardware protection functions. This is a defined operational mode per datasheet Section 3.2 and Table 8-1.
Can S25FL164K0XBHIS20 be used in automotive applications?
Yes - it is qualified to AEC-Q100 Grade 2 (−40 °C to +105 °C) and supports automotive boot memory use cases. However, Infineon recommends S25FL064L for new automotive designs due to extended support and enhanced features.
