3.7.2 Circuit Recommended for the RUIM Card Interface
As the MC509 module is not equipped with a RUIM card socket, a RUIM card socket
need to be placed on the user interface board. The RUIM card signals are
transmitted outwards through the 145-pin LGA interface. Figure 3-16 shows the
circuit of the RUIM card interface.
