2.2.1 Processor – i.MX 7Dual Applications Processor

The i.MX 7Dual family of processors are used for high-performance processing with low-power requirements also incorporating high degree of functional integration. These processors are targeted towards the growing market of connected and portable devices. The i.MX 7Dual processor consists of three cores (2 × Arm®Cortex®-A7 core operating at 800MHz to 1.2GHz, depending on the part number and one Cortex®-M4 core operating at 200MHz). The processor provides a 32-bit DDR3 - 1066 memory interface and also supports DDR3L, LPDDR2 and LPDDR3 interface (DDR3L which is used in this design). This processor has number of other interfaces like Ethernet, EPD Controller, MIPI CSI, DSI and LCD interface, WLAN, Bluetooth, GPS, display, camera sensors along with improved security and tamper protection. A detailed table listing the mapping for each pin on the iMX7D processor is found in Appendix A.
