SE300 is advanced security chip with flash memory for illegal reproduction prevention.It uses mixed RSA public
key algorithm and non-public secret key algorithm.
Also, RSA algorithm decrypt 32bit cipher text with 32bit key.
SE300 supports I2C Interface, +3.3V power and embedded flash memory, It is available in Small Outline
Package(SOP) package with the size of 6.0㎜ x 5.1㎜.
