BAR Series - Serial Memory

Bar Memory Tokens Leveraging industry-standard serial EEPROM memory, Datakey offers BAR tokens with SPI, I2C or microwire interfaces and capacities from 1 Kb to 256 Kb. The tokens feature: Ultra-rugged Construction - Bar memory tokens are solid over-moulded a durable composite, making them impervious to liquids and virtually crush-proof. MIL-STD-810 Tested - Bar memory tokens have been tested to MI-STD-810F standards for immersion, salt-fog, freezing rain, altitude, solar radiation and more. Writable Label - Bar memory tokens come standard with a white, writable label BAR Receptacles Bar receptacles mount to the surface of an enclosure with only the contact pins extending inside. This greatly reduces the volume required inside the enclosure.  Additional features include: IP67 Rating – All Bar receptacles have an IP67 rating and can be supplied with or without a pre-installed adhesive gasket.  The design also minimises radiated emissions. MIL-STD-810 Tested – Bar receptacles have been tested to MIL-STD-810F standards (with and without mated Bar tokens) for shock, vibration, immersion, salt-fog, blowing dust & sand, freezing rain, altitude, solar radiation and more. Open Design – The open design of the Bar receptacles allow for easy in-field cleaning.  The contact system employs a wiping mechanism to clear any material with each insertion. BarLink Programmers It is often desired to use a PC to read data from or write data to a memory token.  The BarLink programmers support all of the Bar tokens and connect to a PC via a USB port.  The programmers come with Windows® drivers and a sample application.  The sample application can be used for troubleshooting when integrating a Bar token into an embedded design, as it provides a known-good way to communicate with the memory device.  For those who wish to develop their own Windows® applications, we offer a development kit with all of the necessary tools, including the programmer.
