USIM Interface
The AirPrime HL77xx modules have one physical USIM interface, USIM1, and an optional internal
USIM or eUICC.
The USIM1 interface allows control of a 1.8V USIM and is fully compliant with GSM 11.11
recommendations concerning USIM functions.
The five signals used by the UIM1 are as follows:
•
UIM1_VCC: Power supply
UIM1_CLK: Clock
•
UIM1_DATA: I/O port
•
•
UIM1_RESET: Reset
UIM1_DET/GPIO3: Hardware SIM detection
•
Refer to the following table for the pad description of the USIM1 interface.
