Product details
Overview
S25FL208K0RMFI041 from Cypress Semiconductor is an 8-Mbit serial NOR flash memory with uniform 4-kB sectors, supporting standard and dual-output SPI interfaces up to 76 MHz, 2.7–3.6 V single-supply operation, and 100k program/erase cycles - used for firmware storage and code shadowing in microcontroller boot systems.
For engineers reviewing the S25FL208K0RMFI041 datasheet, S25FL208K0RMFI041 pinout, S25FL208K0RMFI041 application, or S25FL208K0RMFI041 equivalent, key selection considerations include sector-erase granularity, dual-output read timing, hardware write protection via WP# and HOLD#, and industrial temperature range (–40°C to +85°C) compliance.
Technical Context
The S25FL208K0RMFI041 implements a uniform sector architecture with 256 × 4-kB sectors and 16 × 64-kB blocks, enabling fine-grained data partitioning for parameter storage and firmware updates. It supports SPI Mode 0 and Mode 3 with rising-edge input sampling and falling-edge output timing.
Dual Output Read (3Bh command) uses SI/IO0 and SO simultaneously to double data throughput versus standard SPI, while HOLD# enables bus arbitration without deselecting the device. The Status Register includes WIP, WEL, and BP0–BP3 bits for real-time operation monitoring and configurable memory protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory density | 8 Mbit (1,048,576 bytes), organized as 4,096 pages × 256 bytes - supports byte-aligned firmware image storage and incremental updates. |
| Read speed | 76 MHz FAST READ and DUAL OUTPUT READ - enables sub-100 µs code fetch for boot-time RAM loading. |
| Erase granularity | Uniform 4-kB sectors and 64-kB blocks - allows independent firmware partitioning (e.g., bootloader vs. application) without cross-sector interference. |
| Endurance & retention | 100,000 program/erase cycles and 20-year data retention - validated for long-life industrial control and automotive ECUs. |
| Supply voltage | 2.7 V to 3.6 V single supply - compatible with 3.3 V logic domains and eliminates need for level shifters in host MCU interfaces. |
| Power consumption | 12 mA active current, 15 µA standby - suitable for low-duty-cycle sensor nodes and battery-backed configuration storage. |
| Temperature range | –40°C to +85°C industrial grade - qualified for deployment in factory automation and outdoor edge gateways. |
Pinout & Package
8-pin SOIC (208-mil) package with gull-wing leads, RoHS-compliant, Pb-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select (active-low) | Enables serial interface; high-impedance SO when deasserted - essential for multi-device SPI bus sharing. |
| SCK | Serial Clock Input | Provides timing for all SPI transfers; supports Mode 0/3 polarity/phase configurations - determines clock idle state and edge alignment. |
| SI/IO0 | Serial Input / Dual Output | Input for commands/addresses/data; becomes output during Fast Read Dual Output (3Bh) - doubles bandwidth without extra pins. |
| SO | Serial Output | Outputs status, ID, and read data on falling SCK edge - synchronized with SI/IO0 in dual mode for parallel bit streaming. |
| WP# | Hardware Write Protect | Locks Status Register and memory array when asserted - complements software BP bits for tamper-resistant configuration storage. |
| HOLD# | Hold Control Input | Pauses ongoing SPI transaction without deselecting device - critical for interrupt-driven hosts needing deterministic bus arbitration. |
| VCC | Power Supply | 2.7–3.6 V main supply - powers core logic, charge pumps, and I/O buffers; requires local 100 nF decoupling. |
| GND | Ground Reference | Signal and power return path - must be low-impedance and separated from noisy digital ground planes per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Dual Output Read (3Bh) | Simultaneous data output on SI/IO0 and SO at 76 MHz - reduces boot code load time by ~50% versus standard SPI. |
| Uniform 4-kB Sector Erase | 256 individually erasable sectors - enables atomic firmware patching and secure credential storage without disturbing adjacent data. |
| Hardware + Software Write Protection | WP# pin plus BP0–BP3 bits allow hierarchical lock-down of memory regions - prevents accidental overwrite during field firmware updates. |
| Industrial Temperature Range | –40°C to +85°C operation - validated across thermal cycling and extended burn-in - suitable for uncontrolled ambient deployments. |
| JEDEC ID Support | 90h and 9Fh commands return manufacturer (01h) and device (4017h) IDs - enables runtime flash detection and BOM validation in production test. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S25FL208K0XMFI041 | Same die, 8-pin SOIC 150-mil package - smaller footprint but lower thermal mass and reduced creepage distance. | Preferred for space-constrained PCBs where board area is prioritized over thermal robustness or high-voltage isolation. | Select when layout density outweighs thermal derating needs; verify solder joint reliability under thermal cycling. |
| MX25L8006EM1I-12G | Macronix 8-Mbit flash with 104 MHz max clock, 3-byte address only, no dual-output read support. | Lacks dual-output capability and has coarser 64-kB block-only erase - unsuitable for fine-grained parameter updates. | Choose only if higher clock rate is required and dual-read bandwidth is unnecessary; confirm compatibility with existing SPI driver stack. |
Compared with S25FL208K0RMFI041, the 150-mil variant trades thermal margin for compactness, while the Macronix part sacrifices sector-level flexibility and dual-read efficiency for raw clock speed - neither matches the balanced feature set for embedded boot and configuration use cases.

FAQ
Is S25FL208K0RMFI041 pin-compatible with other S25FL2xxK devices?
Yes - all S25FL2xxK variants share identical 8-pin SOIC pinouts and SPI command sets. Differences are limited to density (2-Mbit to 32-Mbit), speed grade (0R = 76 MHz), and package dimensions (150-mil vs. 208-mil). No PCB redesign is needed when scaling capacity within the same package footprint.
Does S25FL208K0RMFI041 support Quad SPI mode?
No - the S25FL208K0RMFI041 supports only Standard SPI and Dual Output SPI (using SI/IO0 and SO). It does not implement Quad Output or QPI modes. Devices with quad capability belong to the S25FL512S or S25FSxxx families and require different command sets and pin usage.
What is the purpose of the HOLD# pin during active programming?
HOLD# pauses serial communication but does not halt internal program or erase operations. If asserted mid-erase, the device continues the cycle internally while ignoring SCK/SI inputs; SO goes high-impedance. This allows host CPU to service interrupts without corrupting flash state or requiring polling overhead.
How is write protection configured using both WP# and Status Register bits?
WP# provides hardware-level lock: when low, it prevents Status Register writes regardless of BP bit settings. BP0–BP3 bits define protected memory ranges (entire array, top/bottom blocks, or sectors); SRP1 enables permanent protection after setting BP bits. Both layers must be disabled to permit writes - ensuring defense-in-depth against accidental or malicious overwrite.
