The power consumption of the device is very low due to several automatic and software controlled power down modes as well as the low power characteristics of the BeCMOS process. DTMF receiver is also included to enable answering machine functions for the cellular phone. Only a minimal number of external components are needed to meet typical baseband requirements.
