AS3955 − Detailed Description

UID Bytes

The UID block contains four LSB bytes of the 7-byte UID which

is used during anti-collision and selection process. Every IC is

programmed by a unique number during fabrication process at

ams. See UID Coding about details on UID.

This block stores some IC manufacturer data which is

programmed and locked during fabrication process at ams.

UID is treated as IC internal configuration, and is permanently

locked during IC production.

Fabrication Data

Fabrication data are used to set internal configuration and

trimming values. They are treated as IC internal configuration.
