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 0x1, corresponding to the Arm Cortex-M0+ 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.
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 | PIC32CM16/32 GV00 |
| 0x01 - 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.
