 |
|
The Ct-G432 is a high sensitivity, low power ,Surface Mount Device (SMD), that fully utilized SiRF star IV upgraded features. This 48-channel global positioning system (GPS) receiver is designed for a wide range of OEM applications then based on the GPS signal search capabilities of SiRF
star IV GSD4e ROM chipset, SiRF’s newest chipset technology.
The Ct-G432 provides flexible bus interface (Optional :
UART , I2C or SPI ).
Ct-G432 is designed to allow quick and easy integration
into GPS-related applications such as:
- Mobile gaming
- Cellular handsets
- Cameras
- Asset Tracking
- Other location-aware consumer devices Premium on-chip software provides a new level of continuous location awareness by employing.
- *2 Full support for client-based and server-based SiRFInstantFixTM
- *3 Dynamic contextual awareness, temperature monitoring, and MEMS sensors that work in concert to conserve power and boost performance
(*2/*3, Above features should be combined with external EEPROM, please refer to application note.)
