Bits 31:28 – PROCESSOR[3:0]: Processor

Processor

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

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

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

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

Die Number

Identifies the die family.

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

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

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.
