Bits 31:28 – PROCESSOR[3:0] Processor

The value of this field defines the processor used on the device.

Note: For this device, the value of this field is 0x6, corresponding to the Arm Cortex-M4F processor.

Bits 27:23 – FAMILY[4:0] Product Family

The value of this field corresponds to the product family part of the ordering code.

Note: For this device, the value of this field is 0x0 for SAM D5x and 0x3 for SAM E5x Family of base line microcontrollers.

Bits 21:16 – SERIES[5:0] Product Series

The value of this field corresponds to the product series part of the ordering code.


Value	Description
0x00	Reserved
0x01	SAM E51
0x02	Reserved
0x03	SAM E53
0x04	SAM E54
0x05	Reserved
0x06	SAM D51
0x07 - 0x3F	Reserved

Bits 15:12 – DIE[3:0] Die Number

Identifies the die family.

Bits 11:8 – REVISION[3:0] Revision Number

Identifies the die revision number. Refer the product family silicon errata and data sheet clarification document for further information.

Note: The device variant (last letter of the ordering number) is independent of the die revision (DSU.DID.REVISION): The device variant denotes functional differences, whereas the die revision marks evolution of the die.

Bits 7:0 – DEVSEL[7:0] Device Selection

This bit field identifies a device within a product family and product series.
