Motorola Unveils GPS Receiver

Motorola's GPS Products business (Northbrook, IL) has released the latest product in its Oncore GPS receiver line. Ready for software and systems integration, designers can employ the M12 Oncore receiver to bring GPS functionality to their handheld designs.

The M12 has been developed to deliver a small footprint in GPS design. To achieve this task the product sports a 40 x 60 x 10 mm footprint.

The M12 is built using a custom RFIC and a MCORE-based MMC2003 32-b RISC microcontroller. The product offers a less than 15 second acquisition time during hot operation (current almanac, position, time, and ephemeris information stored in the device), a less than 40 second acquisition time during warm operation (current almanac, position, and time information stored in the device), and less than 60 second acquisition time during cold operation (no stored information). It also offers a less than 1 s typical internal reacquisition time.

The receiver operates across the +2.75 to +3.2 VDC supply range dissipating 50 mV maximum power. Other features include a 100 meter accuracy with selective availability (SA) on, a less than 25 meter accuracy with SA off, and a better than 500 ns timing accuracy with SA on.

Th M12 is available with an MMCX RF antenna connector. Antenna power is provided by the host system through one of the power/data connector pins.
