ISK Series Memory Keys
KEYS & TOKENS
Models: ISK1Kb, ISK4Kb, ISK16Kb, ISK64Kb, ISK256Kb
Datakey's ISK Series of Keys are economical 1 Kbit to 256 Kbit data carriers that provide convenient data storage and transfer for high-volume, end-user applications. Each ISK Key contains a non-volatile, serial I²C EEPROM that can be read, erased, and written to via a Keyceptacle® (which is available in panel-mount and board-mount forms) or KeyLink™ Reader/Writers that can easily interface to PCs and other hardware via a standard RS-232 or USB port.

LCK Series Memory Keys
KEYS & TOKENS
Models: LCK1Kb, LCK4Kb, LCK16Kb
Datakey’s LCK keys are economical 1 Kbit, 4 Kbit, and 16 Kbit data carriers that provide convenient data storage and transfer for high-volume, end-user applications that require a low-density, read/write portable memory. Each LCK key contains a non-volatile, serial Microwire EEPROM that can be read, erased, and written to via a Keyceptacle® which is available in both panel-mount and board-mount forms.

SFK Series Memory Keys
KEYS & TOKENS
Models: SFK2Mb, SFK4Mb, SFK8Mb, SFK32Mb
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.
