SFK Series Memory Keys
Datakey's large memory capacity serial flash memory Keys feature a Serial Peripheral Interface (SPI) which is a synchronous serial data link that is standard across many microprocessors and other peripheral chips. It provides a high bandwidth network connection among CPUs and other devices supporting the SPI-compatible bus. The primary applications are data logging, firmware updates, and data transfer. The memory can be written or programmed 1 to 256 bytes at a time, using the Page Write or Page Program instructions. Refer to the SPI Flash Interface Specification for specific sector and page information. The SFK Series features Datakey’s industry-leading solid molded construction, rugged wear-resistant exterior and long-lasting contacts.
