SFK5V 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. From 1 to 256 bytes may be written to the memory using the Page Programming instruction. The entire contents of memory may be read using a single Read instruction. Refer to the Memory SPI Interface Specification for specific sector and page information. The SFK 5V series features 5 volt Vcc and logic operation, and Datakey’s industry-leading solid molded construction, rugged wear-resistant exterior and long-lasting contacts. The SFK 5V series is recommended only for applications requiring 5 volt operation. For all other applications, use the standard SFK Series (3.3 volt).
