Integrated power supply reference design for NXP i.MX 7D processor


Design files


TIDA-050034 is a fully functional development board combining a TI PMIC, TPS65218DO, with NXP i.MX 7Dual Application Processor.

The hardware design consists of DDR3L SDRAM (2x512MB), 64MB Serial NOR Flash, 8GB eMMC 5.0 iNAND, SD Card interface v3.0, 50 pin LCD Connector for external TFT display interface, 1000Base-T Ethernet, USB2.0 Type A and micro-AB, MIPI CSI for external camera interface and mini-PCIe interface.

This design is intended for any project that is using the i.MX 7Solo or i.MX 7Dual processor and requires evaluation of alternate power solutions.

  • Full system-on-board for rapid development of NXP i.MX 7D & i.MX 7S systems
  • Low-power modes & DVFS supported
  • Wifi + Bluetooth wireless connectivity
  • Ethernet, CAN, USB wired connectivity
  • LCD/HDMI/MIPI DSI display options
  • Selectable boot options (SD, eMMC, QSPI)
