Our Trusted Platform Module is a fully integrated security module designed to be integrated into computer systems and other embedded systems. The TPM conforms to TCG v1.2 specifications and includes a cryptographic accelerator capable of computing a 2048-bit RSA signature (key generation, signing, and verification) in 200 ms. Performance of the SHA-1 accelerator is 20 μs per 64-byte block. The AT97SC3204T version complies with the TWI I2C 2-wire protocol.
