MN5772

New SD Interface LSI ■ Overview MN5772 has an interface with the SD Memory Card which is a recordable medium complying with the copyright protection, certifies each other between the SD Memory Card by the mutual authentication of the SDMI standard conformity, encrypt/decrypt the contents with C2 cipher. MN5772 changes decrypted data to the elementary stream data which can be decoded with AAC decoder (MN67736LA).
