Product details
Overview
S25FL208K0RMFI010 from Cypress Semiconductor is an 8-Mbit serial NOR flash memory with uniform 4-kB sectors, supporting standard and dual-output SPI interfaces, 76 MHz read clock rate, 2.7–3.6 V single-supply operation, and 100k program/erase cycles - deployed for firmware storage and code shadowing in industrial microcontroller boot systems.
For engineers reviewing the S25FL208K0RMFI010 datasheet, S25FL208K0RMFI010 pinout, S25FL208K0RMFI010 application, or S25FL208K0RMFI010 equivalent, key selection criteria include sector-erase granularity (4 kB), hardware write protection via WP# pin, JEDEC ID support, and SOIC-208 package compatibility with legacy PCB footprints.
Technical Context
The S25FL208K0RMFI010 implements a uniform sector architecture with 256 × 4-kB sectors and 16 × 64-kB blocks, organized as 4,096 pages of 256 bytes each. It supports SPI Mode 0 and Mode 3 with rising-edge input sampling and falling-edge output timing.
Dual Output Read (3Bh command) enables simultaneous data transfer on SI/IO0 and SO pins at 76 MHz, doubling throughput versus standard SPI reads. The HOLD# and WP# pins provide hardware-level transaction pausing and memory region locking independent of status register configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (1,048,576 bytes), enabling compact firmware image storage without external memory expansion. |
| Supply Voltage | 2.7–3.6 V single supply - compatible with 3.3 V logic domains and eliminates need for level shifters. |
| Read Clock Rate | 76 MHz for both Standard Read (03h) and Dual Output Read (3Bh) - supports fast boot-time code loading into RAM. |
| Erase Granularity | Uniform 4-kB sectors (256 sectors) and 64-kB blocks (16 blocks) - allows fine-grained parameter updates without disturbing adjacent firmware sections. |
| Endurance & Retention | 100,000 program/erase cycles and 20-year data retention - suitable for field-upgradable embedded devices with infrequent but critical updates. |
| Active/Standby Current | 12 mA typical active current; 15 µA typical standby current - meets low-power requirements in always-on industrial controllers. |
| Package | 8-pin SOIC 208-mil (SOC 008) - RoHS-compliant, surface-mount, compatible with automated assembly and legacy board layouts. |
Pinout & Package
8-pin SOIC 208-mil (SOC 008) package with gull-wing leads, 1.27 mm pitch, and RoHS-compliant Pb-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: CS# | Chip Select Input | Active-low enable signal; places device in high-impedance state when high, reducing system power during SPI bus idle periods. |
| 2: SO | Serial Data Output | Primary output for standard SPI reads; outputs data on falling edge of SCK; enters high-Z during HOLD# assertion. |
| 3: WP# | Hardware Write Protect | Active-low pin that locks status register writes when asserted, providing physical override of software-based BP bits. |
| 4: GND | Ground Reference | Signal and power return path; must be connected to system ground plane for stable read/write margins and EMI control. |
| 5: SI/IO0 | Serial Input / Dual Output | Input for commands/addresses/data in standard mode; becomes second data output during Dual Output Read (3Bh). |
| 6: SCK | Serial Clock Input | Master-generated clock; rising edge latches input data; falling edge drives output data; defines maximum 76 MHz interface speed. |
| 7: HOLD# | Hold Control Input | Active-low pause signal; suspends ongoing SPI transactions without deselecting chip or resetting internal state. |
| 8: VCC | Power Supply | 2.7–3.6 V supply input; requires local 100 nF ceramic decoupling capacitor placed within 5 mm of pin per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Uniform 4-kB Sector Architecture | Enables precise firmware patching and parameter storage without erasing unrelated code regions - critical for OTA update safety. |
| Dual Output Read (3Bh) | Delivers 152 MB/s effective throughput (76 MHz × 2 bits/cycle), accelerating boot-time code shadowing from flash to RAM. |
| Hardware + Software Write Protection | Combines WP# pin lock with programmable Block Protect bits (BP0–BP3) to enforce multi-layer memory security policies. |
| JEDEC Manufacturer & Device ID | Supports automatic part identification (90h/9Fh commands), simplifying BOM validation and field firmware compatibility checks. |
| Deep Power-down Mode (B9h) | Reduces current to <1 µA - extends battery life in energy-harvesting sensor nodes during extended sleep intervals. |

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 |
|---|---|---|---|
| MX25L8006EM1I-12G | 8 Mbit, 104 MHz max clock, 3.3 V only (2.7–3.6 V not supported), no HOLD# pin, different status register map. | Lacks hardware hold functionality and wider voltage range - unsuitable for brown-out tolerant designs or mixed-voltage systems. | Select only if 104 MHz read speed is required and HOLD# is unused; verify BP bit mapping differs from Cypress implementation. |
| S25FL108K0XMFI010 | Same family, 8 Mbit, but 1.8 V core (3.0 V I/O), different pinout (SOIC-150), and no Deep Power-down mode. | Designed for ultra-low-power portable devices; incompatible pinout prevents drop-in replacement on S25FL208K0RMFI010 boards. | Choose only for new designs targeting lower active current; not suitable for retrofit or footprint-compatible upgrades. |
Compared with MX25L8006EM1I-12G and S25FL108K0XMFI010, the S25FL208K0RMFI010 uniquely combines industrial temperature range, HOLD# support, wide 2.7–3.6 V operation, and SOIC-208 footprint - making it optimal for legacy industrial controller upgrades where timing predictability and pin compatibility are mandatory.

FAQ
Is S25FL208K0RMFI010 pin-compatible with other S25FL2xxK variants?
Yes, all S25FL2xxK devices in SOIC-208 package share identical pinout and signal definitions, including CS#, SO, WP#, GND, SI/IO0, SCK, HOLD#, and VCC. However, density-specific behaviors (e.g., address wraparound) and status register bit assignments differ - firmware must validate device ID before initialization.
What is the minimum pulse width requirement for the HOLD# signal?
The HOLD# signal requires a minimum low pulse width of 30 ns to reliably enter hold state, and a minimum high pulse width of 30 ns to exit. These values are specified in AC Characteristics Table 9.6 of the datasheet and apply across full temperature and voltage ranges.
Does S25FL208K0RMFI010 support Quad SPI mode?
No. The S25FL208K0RMFI010 supports only Standard SPI (single I/O) and Dual Output SPI (two I/O lines). It does not implement Quad SPI instructions (e.g., 4-4-4 mode) or dedicated IO1–IO3 pins - confirmed by pin count, block diagram, and command set documentation.
How is write protection configured when both WP# pin and status register BP bits are active?
When WP# is asserted low, it overrides all software-configured Block Protect bits and prevents any status register write - including attempts to clear BP bits. This hardware lock ensures fail-safe protection even if firmware is compromised or incorrectly initialized.
