Function Features
Application processor Application processor to run customer application code
32-bit ARM Cortex-A7 up to 1.3 GHz running the Linux operating system
Flash + DDR are large enough to allow for customer’s own software
applications
Interfaces Rich set of interfaces, including:
SD/MMC Card Interface supporting SD3.0 standard
SDIO for external WiFi transceiver supporting SDIO3.0 standard
SGMII for external Ethernet transceiver
Compliant with IEEE802.3
Full duplex operation at 1 Gbps
Half/full duplex operation at 10/100 Mbps
Support for VLAN tagging
Support for IEEE1588, PTP (Precision Time Protocol)
USB2.0 – USB port is typically used for:
Flashing of firmware and module configuration
Production testing
Accessing the Application Processor’s file system
AT command access
High-speed WWAN access to external host
Diagnostic monitoring and debugging
NMEA data to an external host CPU
HSIC (Optional)
High-speed 480 Mbps (240 MHz DDR) USB transfers are 100% host driver
compatible with traditional USB cable connected topologies
Bidirectional data strobe signal (STROBE)
Bidirectional data signal (DATA)
No power consumption unless a transfer is in progress
