The S25FL208K0RMFI010 is an 8-Mbit, 3.0-V SPI NOR Flash memory device featuring fast read speeds, low-power standby modes, and highly reliable non-volatile storage. It is built on Infineon/Cypress's proven floating-gate NOR Flash technology, delivering long data retention and excellent endurance for code execution and frequent read operations.
The device uses a serial SPI interface that supports single, dual, and fast-read modes, enabling efficient integration into microcontroller-based systems. Its uniform 4-KB sector architecture simplifies memory organization for firmware storage, boot loaders, configuration data, and parameter tables.
With an industrial temperature range, hardware/software write protection, and low-power sleep mode, the S25FL208K0RMFI010 is suitable for battery-powered devices, consumer electronics, embedded systems, and industrial automation where stability and long-term reliability are mandatory.
With ultra-low standby current and an efficient sleep mode, the S25FL208K0RMFI010 is ideal for battery-powered systems that require long operating life. It reduces unnecessary energy consumption while maintaining fast wake-up performance.
Supporting up to 75-MHz SPI clock and fast-read instructions, the memory delivers quick access times. Uniform sectors and robust erase/write algorithms provide stable long-term data retention and predictable behavior in embedded designs.
Integrated hardware and software write protection mechanisms safeguard configuration data, boot code, and application firmware against accidental or unauthorized modification-an essential feature for secure embedded devices.
The industry-standard SPI interface makes the device compatible with nearly all 8-bit, 16-bit, and 32-bit microcontrollers. Its compact SOIC-8 package simplifies PCB layout and reduces BOM costs for space-constrained systems.
The memory array consists of 4,096 pages of 256 bytes each, organized into 4-KB sectors for efficient firmware updates and configuration storage.
Supports SPI read frequencies up to 75 MHz with multiple read modes, enhancing throughput in embedded applications that require rapid code-execution reads.
Includes block protection, lock bits, and software-controlled write commands, safeguarding critical sections of memory from accidental overwrites or system-level tampering.
