Remote SIM Access
MC75i supports Remote SIM Access. RSA enables MC75i to use a remote
SIM card via its serial interface and an external application, in addition to
the SIM card locally attached to the dedicated lines of the application inter-
face. The connection between the external application and the remote SIM
card can be a Bluetooth wireless link or a serial link.
The necessary protocols and procedures are implemented according to the
“SIM Access Profile Interoperability Specification of the Bluetooth Special
Interest Group” (SAP).
Firmware update
Generic update from host application over ASC0, ASC1 or USB.
Interfaces
Module interface
80-pin board-to-board connector.
2 serial interfaces
ASC0:
•
8-wire modem interface with status and control lines, unbalanced, asyn-
chronous
•
Adjustable baud rates: 300bps to 921,600bps
•
Autobauding: 1,200bps to
460,800
bps
•
Supports RTS0/CTS0 hardware handshake and software XON/XOFF
flow control.
•
Multiplex ability according to GSM 07.10 Multiplexer Protocol.
ASC1:
•
4-wire, unbalanced asynchronous interface
•
Adjustable baud rates: 300bps to 921,600bps
•
Supports RTS1/CTS1 hardware handshake and software XON/XOFF
flow control
USB
Supports a USB 2.0 Full Speed (12Mbit/s) slave interface.

C
I
2
C bus for 7-bit addressing and transmission rates up to 400kbps. Pro-
grammable with AT^SSPI command.
Alternatively, all lines of the I²C interface are configurable as SPI.
SPI
Serial Peripheral Interface for transmission rates up to 6.5 Mbps.
Programmable with AT^SSPI command.
If the SPI is active the I²C interface is not available.
