9.1 SAMA7G5 Series System-in-Package (SiP)

The Microchip SAMA7G54 System-On-Module Series embeds the SAMA7G5 Series SiP, which integrates the Arm Cortex-A7 CPU-based SAMA7G54 MPU with a 2-Gbit DDR3L SDRAM in a single package.

By combining the SAMA7G54 with DDR3L 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 SAMA7G5 Series SiP data sheet (see Reference Documents).

The SAMA7G5 Series SiP is available in a 18x21 mm 427-ball SBS TFBGA package.

The Microchip SAMA7G54 System-On-Module 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 internal Power Management Unit (MCP16502) respecting the microprocessor power sequence timing. It is used to reset the internal microprocessor and the rest of the customer application board. It can then be forced externally in case of a system crash.
  • The NRST_OUT signal is an output pin generated by the SAMA7G54 reset controller. On the customer application, it can be used to reset specific interfaces such as 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.
