8.1 Power Supplies

Table 8-1. SAM9X60D1G-I/LZB Power Supplies
Pin No.	Name⁽¹⁾	Power Type	Output Current Capability	Power Domains
123	VDDBU	Input	–	Backup supply input
56	VDDQSPI	Input	–	QSPI supply input
41, 42	VDD_3V3	Output	600 mA	I/O supply and customer application output
54, 55	VDDIOM	Output	600 mA	DDR memory supply and customer application output
52, 53	5V_MAIN	Input	–	System power input
29	VLDO1	Output	300 mA	Adjustable output depending on application settings

Note:

VDDBU and VDDQSPI need to be supplied externally on their respective pins. Failing to do so will prevent the MPU from working properly.

The SAM9X60D1G-I/LZB System-On-Module is supplied by a unique input (5V_MAIN) and its internal supplies are all delivered by a power management unit (MCP16501), as shown in the Power Architecture diagram below.
