Serial Memory → Made rugged and portable.

Datakey serial memory products make it easy to add robust, portable memory to your embedded device. We use industry-standard serial EEPROM and serial flash memory to simplify integration, reduce time-to-market and virtually eliminate obsolescence concerns.

Simplified Integration Speeds Time-To-Market

The Serial Memory line utilises industry-standard serial EEPROM and serial (NOR) Flash, simplifying integration and speeding time-to-market. For applications where you don’t need gigabytes of portable storage, avoid the complexities of USB flash drive or SD card integration and choose a proven Serial Memory solution. If your application does call for gigabytes of storage, avoid the shortcomings of consumer memory devices and check out the RUGGEDrive™ line.

SPI Flexibility

While all of the Serial Memory form factors are available with Microwire, I2C and SPI serial interfaces, only SPI has the advantage of supporting both EEPROM and NOR flash devices. Many of our OEM customers who utilised a lower-capacity EEPROM device were able to also use a larger NOR flash device as a way of updating the system’s firmware. Since the receptacle was already in the design, it was like they got firmware updates “for free”!

Long-term Availability

Unlike USB flash drives and SD cards that have short product life cycles, the Serial Memory line uses industry-standard serial EEPROM and serial NOR Flash memory. These memory technologies have extremely long product life cycles, especially when compared to the NAND Flash memory used in consumer products.
