Implementation
ASC1 without Java:
•
4-wire, unbalanced asynchronous interface
•
1.2kbps to 460kbps
•
Autobauding TBD
•
Supports RTS1/CTS1 hardware handshake and software
XON/XOFF flow control
ASC1 under Java: System.out
Supports a USB 2.0 Full Speed (12Mbit/s) slave interface.
I 2 C bus for 7-bit addressing and transmission rates up to 400kbps.
Programmable with AT^SSPI command.
Alternatively, all pins of the I²C interface are configurable as 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.

Supported SIM cards: 3V, 1.8V
50Ohms. External antenna can be connected via antenna
connector or solderable pad.
80-pin board-to-board connector
•
Switch-on by hardware pin IGT
•
Switch-off by AT command (AT^SMSO)
•
Automatic switch-off in case of critical temperature and
voltage conditions.
•
Orderly shutdown and reset by AT command
•
Emergency reset by hardware pin EMERG_RST and IGT.
Supports management of rechargeable Lithium Ion and Lithium
Polymer batteries
