CC4000-TC6000GN
The following product brief applies to the
TC6000GN – a highly-integrated GPS
module offered by GNS using
Texas Instruments’ SimpleLink™
GPS CC4000. The GNS TC6000GN
module enables applications benefitting
from precise time, location, and/or
velocity data. This solution provides
industry standard NMEA protocol data
for accurate time, position, latitude,
longitude, satellite status, course
and speed. This solution provides
industry standard NMEA protocol data
for accurate time, position, latitude,
longitude, satellite status, course and
speed. Autonomous warm start and hot
start are enabled by on-board memory,
improving start-up performance. A single
GPIO is used to initiate a GPS fix (Push-
to-fix), activating power management
for active and deep sleep modes.
Applications requiring high precision
timing benefit from an independent
programmable PPS generator. Further,
the GPS driver and firmware is fully
integrated into the module, greatly
minimizing loading on the host CPU, and
reducing system complexity. This allows
GPS functionality to simply integrate
with very small MCUs and MPUs. This
solution is provided as a module to
help customers reduce development
time, lower manufacturing costs, save
board space, and minimize RF and GPS
expertise required.
