MAX66040

Unique Identification Number (UID)

Each MAX66040 contains a factory-programmed and

locked identification number that is 64 bits long

(Figure 3). The lower 36 bits are the serial number of

the chip. The next 8 bits store the device feature code,

which is 03h. Bits 45 to 48 are 0h. The code in bit loca-

tions 49 to 56 identifies the chip manufacturer, accord-

ing to ISO/IEC 7816-6/AM1. This code is 2Bh for

Maxim. The code in the upper 8 bits is E0h. The UID is

read accessible through the Get UID and Get System

Information commands. The lower 32 bits of the UID are

transmitted in the PUPI field of the ATQB response to

the REQB, WUPB, or SLOT-MARKER command. By

default, the upper 32 bits of the UID are factory pro-

grammed into the application data field, which is trans-

mitted as part of the ATQB response. This way the

master receives the complete UID in the first response

from the slave. See the

Network Function Commands

section for details.
