The S25FL208K supports the standard Serial Peripheral Interface (SPI), and a high performance Dual output using SPI pins: Serial Clock, Chip Select, Serial SI/IO0, SO, WP and HOLD . SPI clock frequencies of up to 76 MHz are supported along with a clock rate of 76 MHz for Dual Output Read. The S25FL208K array is organized into 4,096 programmable pages of 256 bytes each. Up to 256 bytes can be programmed at a time. Pages can be erased in groups of 16 (4-kB Sector Erase), groups of 256 (64-kB Block Erase) or the entire chip (Chip Erase). The S25FL208K has 256 erasable sectors and 16 erasable blocks. The small 4 kB sectors allow for greater flexibility in applications that require data and parameter storage. A Hold pin, Write Protect Pin and programmable write protection provide further control flexibility. Additionally, the S25FL208K device supports JEDEC standard manufacturer and device identification.
