Patent ID: 11863209
Assignee: PIXART IMAGING INC.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. An integrated circuit, comprising:
a non-volatile memory circuit, for securely and permanently recording and protecting a key data content having Y bits;
a programmable memory circuit, for storing a user configuration data content having X bits greater than Y bits;
a decision circuit, coupled to the non-volatile memory circuit and the programmable memory circuit, arranged for:
receiving the key data content having Y bits and the user configuration data content having X bits;
converting the user configuration data content having X bits into a user configuration key content having Y bits;
comparing the user configuration key content having Y bits with the key data content having Y bits;
selecting a fallback configuration data content having X bits as an output data when the user configuration key content does not match the key data content; and
selecting the user configuration data content having X bits as the output data when the user configuration key content matches the key data content; and

a processing circuit, coupled to the decision circuit, for receiving the output data of the decision circuit and performing at least one corresponding capability operation according to the output data.
