The Universal Subscriber Identity Module or USIM card is the logical extension of the SIM card into the 3G
environment, as an evolution of the SIM card. It can be used for support of GSM Phase 2 and 3G modes.
The X-GOLD213 USIM interface is compatible with ISO 7816-3 IC card standard, required by GSM11.12 (3.0V
and GSM 11.18 (1.8V) standards. It supports both 1.8V and 3.0V SIM Cards with T=0 and T=1 protocols
supported by hardware. For 3V SIM cards, the nominal supply voltage is 2.85V. The SIM card is provided with
a 3.25MHz clock and can be configured into low power modes. All SIM related clock signals are controlled by
the SIM_CTRL register in X-Gold213.
