Product details
Overview
S25FL208K0RMFI011 from Cypress Semiconductor is an 8-Mbit serial NOR flash memory with uniform 4-kB sectors, operating from 2.7V to 3.6V, supporting standard and dual-output SPI up to 76 MHz, and delivering 1.5 ms page program time for embedded code storage and parameter retention in industrial microcontroller systems.
For engineers reviewing the S25FL208K0RMFI011 datasheet, S25FL208K0RMFI011 pinout, S25FL208K0RMFI011 application, or S25FL208K0RMFI011 equivalent, key selection criteria include sector-erase granularity (4 kB), JEDEC-compliant ID support, hardware write protection via WP# and HOLD#, and compatibility with legacy SPI controllers requiring fast read dual output (3Bh) for boot-time code shadowing.
Technical Context
The S25FL208K0RMFI011 implements a uniform sector architecture with 256 × 4-kB sectors and 16 × 64-kB blocks, enabling fine-grained firmware partitioning. It supports SPI Mode 0 and Mode 3 with rising-edge input sampling and falling-edge output timing, and uses SI/IO0 as bidirectional data line during Fast Read Dual Output (3Bh) command execution.
Its status register includes WIP and WEL bits for operation state visibility and write enable control, while BP0–BP3 bits provide non-volatile software-based memory protection. The device enters high-impedance SO state during HOLD# assertion without interrupting ongoing erase/program cycles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (1,048,576 bytes), organized as 4,096 pages × 256 bytes for deterministic firmware image layout |
| Supply Voltage | 2.7 V to 3.6 V - compatible with 3.3 V logic domains without level shifting |
| Max Clock Frequency | 76 MHz for both Standard Read (03h) and Fast Read Dual Output (3Bh) - enables 19 MB/s effective throughput in dual mode |
| Erase Granularity | 4 kB sector erase (20h) and 64 kB block erase (D8h) - supports modular firmware updates without full chip erase |
| Endurance & Retention | 100,000 program/erase cycles and 20-year data retention - validated for long-life industrial logging applications |
| Power Consumption | 12 mA active current, 15 µA standby - suitable for low-duty-cycle sensor nodes with infrequent firmware access |
| Package | 8-pin SOIC 208-mil (SOC 008) - industry-standard footprint with RoHS-compliant lead-free finish |
Pinout & Package
8-pin SOIC 208-mil (SOC 008) package with gull-wing leads, 1.27 mm pitch, and RoHS-compliant Pb-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: CS# | Chip Select Input | Active-low enable; places SO in high-impedance when deasserted, reducing bus contention in multi-device SPI systems |
| 2: SO | Serial Data Output | Standard single-bit output during 03h/0Bh reads; tri-stated during HOLD# or CS# high |
| 3: WP# | Hardware Write Protect | Low-active pin that locks Status Register writes when asserted, complementing BPx software protection |
| 4: GND | Ground Reference | Signal and power return path; must be low-impedance connection to minimize noise coupling into SPI signals |
| 5: SI/IO0 | Serial Input / Dual Output | Input for commands/addresses/data in standard mode; becomes second data output during 3Bh dual-read cycles |
| 6: SCK | Serial Clock Input | Edge-triggered clock; rising edge latches input, falling edge drives output per SPI Mode 0/3 compliance |
| 7: HOLD# | Hold Control Input | Pauses ongoing SPI transfers without deselecting device; maintains internal state during host arbitration delays |
| 8: VCC | Power Supply | 2.7–3.6 V supply; requires local 100 nF ceramic decoupling placed within 5 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Uniform 4-kB Sector Architecture | Enables precise firmware patching and configuration storage without erasing unrelated sections |
| Fast Read Dual Output (3Bh) | Doubles data rate over standard SPI by using SI/IO0 as second output, accelerating boot-time code loading |
| Hardware + Software Write Protection | WP# pin and BP0–BP3 bits allow layered protection: hardware lock for critical registers, software lock for configurable memory regions |
| JEDEC Manufacturer/Device ID Support | 90h and 9Fh commands return fixed Cypress ID (01h) and device-specific ID (4017h), enabling runtime flash identification in multi-vendor BOMs |
| Auto-Increment Read Capability | Continuous sequential reads across page boundaries without address retransmission, simplifying bootloader implementations |

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 |
|---|---|---|---|
| S25FL208K0XMFI010 | Same die, 8-pin SOIC 150-mil package; 0.15 mm shorter body length | Requires PCB footprint revision; identical timing and command set | Select when board space constraints favor compact SOIC-150 |
| MX25L8006EM1I-12G | Macronix 8-Mbit flash; 104 MHz max clock, 2.7–3.6 V, but no dual-output read mode | Lacks 3Bh instruction; relies on faster single-line clock for equivalent throughput | Choose only if host controller lacks dual-output SPI support and higher clock tolerance is acceptable |
Compared with S25FL208K0XMFI010, the 208-mil SOIC offers better mechanical stability in high-vibration environments; versus MX25L8006EM1I-12G, the dual-output capability delivers 2× data bandwidth at same clock frequency-critical for time-constrained boot sequences.

FAQ
Is S25FL208K0RMFI011 pin-compatible with earlier S25FL204K or S25FL208S devices?
No. While all belong to the S25FL family, S25FL208K0RMFI011 uses a different die revision and command set than S25FL204K. The S25FL208S shares the same pinout but lacks dual-output read (3Bh) support and has distinct timing parameters. Direct substitution requires validation of command compatibility, timing margins, and status register bit definitions.
Does S25FL208K0RMFI011 support Quad SPI (QSPI) mode?
No. The S25FL208K0RMFI011 supports only standard SPI and dual-output SPI modes. It does not implement Quad I/O instructions (e.g., 6Bh, EBh) or quad-capable status register bits. Devices with QSPI support in this density class include the S25FL116K and later S25HL series.
What is the maximum junction temperature during continuous 76 MHz operation?
Per datasheet Section 9.3, the device is rated for operation up to +85°C ambient (industrial grade). At 76 MHz with VCC = 3.3 V, typical power dissipation is ≤150 mW. With standard SOIC-208 thermal resistance (θJA ≈ 150°C/W), junction temperature remains ≤105°C - within safe operating limits for industrial applications.
Can HOLD# be used during a sector erase operation?
Yes. Asserting HOLD# during an active sector erase (20h) pauses the SPI interface but does not halt the internal erase cycle. SO goes high-impedance, SI/SCK are ignored, and the erase continues autonomously. Communication resumes after HOLD# deassertion and CS# remains low, with WIP bit indicating ongoing operation.
