BM210012WT27 35 Wavenet Technology
It is acceptable to drive this input with a NPN transistor or N-channel
MOSFET connected to ground with a 4k7Ω pull-up resistor to 3.3V
Warning: When the modem is turned off using the HOSTPWR_ON
signal, all other signals connected to the Data Interface Connector
should also be turned off or set to 0V otherwise the modem may remain
powered on via these signals.
Modem Reset Input
The reset input line (HCRESET) is an active low input signal (TTL
compatible) and is fitted with a 6.8kΩ series resistor and clamp diode
to the internal supply line for input protection. Internally it is passively
pulled high (after the series resistor) to the supply rail (3.3V) and is
asserted with an actively driven low signal to ground. The electrical
interface specification and equivalent circuit is as follows:
Reset Input Equivalent Circuit
Reset Electrical Characteristics
Parameter Range Low High
Input Voltage 0-3.3 V
OR
0-5V 0.5 V (max) 2.0 V (min)
Input Current 200 µA (max) 200 µA (max)
Pulse width 5mS (min)
Serial Communications Interface
The modem communicates with the controller using the Data Interface
Port connection interface. The asynchronous serial interface on the
Boomer II OEM Modem operates at 3.3V and can be controlled by a
wide variety of micro controllers and microprocessors. The modem can
be connected directly to a micro controller or through a universal
asynchronous receiver/transmitter (UART) to a microprocessor data
bus.
