TCM 515 provides a highly integrated solution in a small form factor including the required func- tionality for encryption, decryption and authenti- cation of secure telegrams without the need for external components. TCM 515 receives radio telegrams based on an external antenna connected via the host PCB. It can filter, decrypt and authenticate these tele- grams before forwarding them to an externally connected host processor or host PC via a serial interface (UART). The serial interface operates according to EnOcean ESP3 standard with the option to use higher interface speeds (TURBO mode) to reduce latencies. ESP3 messages received from the external host will be encrypted and authenticated as required and then transmitted as EnOcean radio tele- grams.
