Low Power High-performance GNSS Positioning Chip
The ER-GNSS-C01/02 adopts a 28nm process and a smart PMU design that combines ultra-low power consumption and extreme miniaturization to significantly improve the battery life of user devices.
The ER-GNSS-C01/02 is designed for global applications and supports BDS, GPS, GLONALSS, and Galileo for joint positioning of multiple systems. High integration design saves peripherals and on-board area. The ER-GNSS-C01 is a QFN40 package, and the ER-GNSS-C02 is a WLCSP package.
Key Features
Ultra-low power consumption
Support BDS, GPS, GLONALSS, Galileo IV system, BDS and GLONASS cannot run at the same time
Built-in anti-interference module
High integration, simple peripheral devices, save cost
Extremely compact, compatible with mainstream packages
