Operating voltage range

Last Updated: December 30, 2011

What is the minimum operating voltage for WirelessUSB LS?


WirelessUSB has a supply voltage range of 2.7-3.6V. The device should never be exposed to a voltage of more than 3.9V, and operation is not guaranteed above the 3.6V maximum. Cypress guarantees that all devices will operate correctly at 2.7V, and typical devices will operate a little below this voltage, depending on operating temperature and device-to-device variation. The designer should carefully consider whether or not to detect when the supply voltage falls below 2.7V, and to cease operating at that point, or whether to continue to operate the radio until correct operation ceases.
