  • Page 2: Product Description

    Product Description Product Description EB-5318RF GPS module features high sensitivity, low power and ultra small form factor. This GPS module is powered by SiRF Star IV, it can provide you with superior sensitivity and performance even in urban canyon and dense foliage environment. With SiRF CGEE (Client Generated Extended Ephemeris) technology, it predicts satellite positions for up to 3 days and delivers CGEE-start time of less than 15 seconds under most conditions, without any network assistance.

  • Page 4: Electrical Specification

    OFF command is a software feature based on interrupts related to rising and/or falling edges and/or sensing of pin levels. 3. The WAKE_UP pin is an output from the EB-5318RF used to enable an external PMIC. A low on this output indicates that the EB-5318RF is in one of its low-power states (KA-only, Hibernate, or Standby mode) and requires no more than 60µA of current on the VIO_18 input.
