9.1 SAMA7D65 System-in-Package (SiP)

The Microchip SAMA7D65 System-On-Module Series embeds the SAMA7D65D2G, which integrates the Arm® Cortex®-A7 CPU-based SAMA7D65 MPU with a 2-Gbit DDR3L SDRAM in a single package.

By combining the SAMA7D65 with a DDR3L memory in a single package, PCB routing complexity, area and number of layers are reduced. This makes board design easier and more robust by facilitating design for EMI, ESD and signal integrity.

For more information, refer to the SAMA7D65 SiP Series data sheet (see Reference Documents).

The SAMA7D65D2G SiP embedded on this System-On-Module is housed in an 18 mm x 21 mm 427-ball TFBGA package.

The Microchip SAMA7D65 System-On-Module Series provides global system Reset (NRST, NRST_OUT) and Shutdown (SHDN) pins to the application board.

Note:
  • The NRST signal is an input/output pin generated by the MCP16502 internal Power Management Unit, respecting the microprocessor power sequence timing. It is distributed internally to the microprocessor and can be forced externally for system-level control.
  • The NRST_OUT signal is an output pin generated by the SAMA7D65 reset controller. In the customer application, it can be used to reset specific interfaces such as the Ethernet PHY, Wireless Solution or another device.
  • The SHDN pin is an output pin managed by the application software. In an application case, the pin can switch on/off the 5V_MAIN external main supply.
