C bus for transmission rates up to 400kbps.
Programmable with AT^SSPI command.
Alternatively all pins 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.
The I²C interface is not available by using the SPI interface.
Audio Analog (Microphone, Earpiece)
SIM interface Supported SIM cards: 3V, 1.8V
Antenna Connected via antenna SMA connector
Power on/off, Reset
Power-on Switch on via On/Off push button, ONOFF line on IO interface
connector,
DTR line at RS232 interface or IGT_IN line at power connector
(available with recommended power supply)
Power-off
• Normal switch-off by AT^SMSO or On/Off push button
• Emergency switch-off via EMERGOFF line at power
connector
• Automatic switch-off in case of critical temperature and
voltage conditions
Reset Orderly shutdown and reset by AT command
Special features
Real time clock Timer functions via AT commands
GPIO 10 I/O pins of the application interface are programmable as
GPIO. Programming is done via AT commands. Alternatively,
GPIO pin 10 is configurable as pulse counter.
Pulse counter Pulse counter for measuring pulse rates from 0 to 1000
pulses/sec.
If the pulse counter is active the GPIO pin 10 is not available.
ADC inputs Analog-to-Digital Converter with two balanced analog inputs for
measuring external voltages.
