Bits 7 to 3: Device ID (ID[7:3]). The upper five bits of the IDR are used to display the DS26518 ID.
Table 10-16. Device ID Codes in this Product Family
Bits 2 to 0: Silicon Revision Bits (ID[2:0]). The lower three bits of the IDR are used to display a sequential
number denoting the die revision of the chip. The initial silicon revision = “000” and is incremented with each silicon
revision. This value is not the same as the two-character device revision on the top brand of the device. This is due
to the fact that portions of the device assembly other than the silicon may change, causing the device revision
increment on the brand without having a revision of the silicon. ID0 is the LSB of a decimal code that represents
the chip revision.
