Bits 31:28 – PROCESSOR[3:0] Processor

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

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

The value of this field corresponds to the Product Family part of the ordering code.

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

The value of this field corresponds to the Product Series part of the ordering code.

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. 0x0=rev.A, 0x1=rev.B etc.

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. Refer to the Ordering Information for device configurations and corresponding values for Flash memory density, pin count and device variant. For further information, refer to Device Identification.
