The Connected Card Application Reference Design (CCARD) is a Qualcomm Technologies, Inc. (QTI) reference design and software development platform for automotive telematics platforms. Central to the CCARD is the MDM9250-6 system on-a-chip, Qualcomm Snapdragon™ X16 LTE modem.
The CCARD’s provides a near commercial-grade Telematics Control Unit (TCU) that provide high-speed wide area networking (WAN) connectivity from an automobile. OEM customers can directly leverage the CCARD for development of their commercial devices. This platform also enhances the software development process with access to peripheral debug ports, a serial console interface, and a USB debug port.
Major Features Include:
- Gigabit LTE modem that can achieve TCP/IP connectivity to the Internet.
- CAN/LIN connectivity with vehicle CAN bus allows hybrid use cases; this offers the opportunity to build trusted services and remote access to the vehicle.
- Hotspot WLAN services for users in the vehicle; operation at dual bands 2.4 GHz and 5 GHz; capable of 802.11ac high speed connectivity.
- Connectivity over a gigabit Ethernet interface, enabling an in-car LAN and a gateway to the Internet. This provides the opportunity to form a network with in-vehicle infotainment (IVI), rear seat entertainment systems, and other control systems.
- Location services engine – Global Navigation Satellite System (GNSS) compounded by a dead reckoning engine to assist with the navigation and the vehicle tracking system. The design also includes an onboard six-axis gyroscope and accelerometer to enhance the position tracking.
- Bluetooth connectivity, Ethernet AVB and Automotive Audio Bus (A2B), enabling voice and music interfaces.
- Bluetooth LE (LE) connectivity for keyless entry.
- Onboard audio codec to facilitate eCall.
- Onboard antenna switch matrix to detect a broken antenna and switch to available ones. There is also an onboard antenna as a last solution.
