Security IC |
|
|
 |
|
|
Security IC is a MCU firmware protecting IC by using special
coding
algorithm and serial number generated from a program library.
Through the verification process, the information of
manufacturing product is protected and thus MCU firmware is
ensured from decryption, or other counterfeit actions.
Security IC
can be applied in different kinds of MCU. This firmware is
highly secured, cost-efficient, and easily operated.

The range of
L6101 operation voltage is between 2.2V to 5.5V, providing
IIC transmission interface to support MCU designers transmit
security key and receive verification code. In addition,
every manufacturer serial number is built in L6101. The
verification code will be changed according to different
manufacturer serial number and security key, so as to ensure
the correct matching user MCU with security IC. |
