32-bit ARM-Based Microcontrollers Table 3-1. SAM D21L Device Identification Values Device Variant DID.DEVSEL Device ID (DID)
Reserved 0x00 - 0x61 SAMD21E16L 0x62 0x1001143E SAMD21E15L 0x63 0x1001143F Reserved 0x64 - 0x86 SAMD21G16L 0x87 0x10011457 Reserved 0x88 - 0xFF
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. The device variant denotes functional differences, whereas the die revision marks evolution of the die. © 2017 Microchip Technology Inc.
