Product details
Overview
S25FL164K0XMFI013 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 firmware update storage for industrial microcontroller systems.
For engineers reviewing the S25FL164K0XMFI013 datasheet, S25FL164K0XMFI013 pinout, S25FL164K0XMFI013 application, or S25FL164K0XMFI013 equivalent, key selection criteria include Quad I/O read performance, security register OTP protection, AEC-Q100 Grade 2 qualification, and migration path to S25FL064L.
Technical Context
This device implements JEDEC-standard SPI command set with support for modes 0 and 3, SFDP v1.5 compliance, and Execute-In-Place (XIP) optimized continuous/wrapped read modes. Its 90 nm floating gate process enables stable operation across −40 °C to +105 °C (Industrial Plus range) with single 2.7–3.6 V supply.
Security architecture includes three 256-byte OTP-protected security registers, 8-byte unique ID, pointer-based block protection, and lock-down-until-power-cycle functionality. Program suspend/resume and erase suspend/resume allow real-time host control during non-volatile operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 Mbit (8 Mbyte) - sufficient for full MCU boot image plus firmware update partition |
| Interface | SPI Multi-I/O (x1/x2/x4) - reduces pin count vs parallel NOR while maintaining XIP viability |
| Max Read Speed | 54 MB/s (Quad Read @ 108 MHz) - matches x16 parallel NOR bandwidth with 6-pin interface |
| Erase Granularity | 4 kB sectors / 64 kB blocks - enables fine-grained firmware patching without full chip erase |
| Endurance & Retention | 100K cycles / 20 years - supports field-updatable systems with multi-year service life |
| Operating Voltage | 2.7 V to 3.6 V - compatible with 3.3 V logic rails and brown-out tolerant power domains |
| Temperature Range | −40 °C to +105 °C (Industrial Plus) - qualified for under-hood automotive and industrial edge controllers |
Pinout & Package
Package: 8-lead SOIC (208 mil), RoHS-compliant, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select Input | Active-low enable for command decoding; must be held low for entire command sequence |
| SCK | Serial Clock Input | Edge-triggered clock up to 108 MHz; phase/polarity configurable per SPI mode 0/3 |
| IO0 (SI) | Serial Data Input / I/O | Primary data line for instruction/address input and single/dual/quad read data output |
| IO1 (SO) | Serial Data Output / I/O | Output-only in SIO mode; bidirectional in DIO/QIO for dual/quad data transfer |
| IO2 (WP#) | Write Protect Input / I/O | Hardware-level sector protection when asserted low; disabled in Quad I/O mode |
| IO3 (HOLD#) | Command Hold Input / I/O | Suspends ongoing read/program/erase without CS# deassertion; disabled in Quad I/O mode |
| VCC | Supply Voltage | 2.7–3.6 V core/I/O rail; internal regulation ensures stable flash operation across voltage range |
| VSS | Ground | Signal reference for all I/O and internal circuitry; requires low-impedance PCB connection |
Key Features
| Feature | Design Value |
|---|---|
| Quad Read at 108 MHz | Enables 54 MB/s sustained throughput - eliminates bottleneck for XIP execution from flash |
| Program/Erase Suspend & Resume | Allows host CPU to interrupt flash operations for time-critical tasks without data loss or timeout failure |
| Three 256-byte OTP Security Registers | Stores immutable keys, calibration data, or device-specific credentials resistant to overwrite or readback |
| Pointer-Based Block Protection | Configurable 4 kB–full-memory protection range via status register bits - no external hardware needed |
| JEDEC SFDP v1.5 Compliance | Enables automatic configuration by host bootloader without hard-coded timing or command tables |
