  • Method and circuit for interfacing a modem in a wireless communication device to a subscriber interface module
    Patent number: 6839570
    Abstract: A circuit for interfacing a modem in a wireless communication device to a Subscriber Interface Module (SIM) includes a modem controller, a Universal Asynchronous Receiver/Transmitter (UART) connected to the modem controller, a programmable clock circuit adapted to generate a SIM clock and a UART clock independently of one another based on a common clock and a control signal provided to the programmable clock circuit, a reset circuit to generate a SIM reset signal, and a power control circuit to control powering on and off the SIM, all on an integrated circuit chip. The circuit also includes a Bus Interface circuit to interface the modem to the SIM using a common data line.
