73M2901CE Data Sheet

DS_2901CE_031

1 Hardware Description

The 73M2901CE is designed to operate from a +3.6 to +2.7 volt supply with low power consumption

(~30 mW @ 3.0 volts). The modem supports automatic standby idle mode. The modem will also accept

a request to power down from the DTE via hardware control. No additional major components are

required to complete the modem core logic. The modem provides direct firmware LED support via the

port pins (pins 3, 4, 5, 6, 31, and 32).

The 73M2901 CE includes the following hardware features:

•

Fully self-contained. “AT” Command interpreter and data pump.

User pins available.

Synchronous serial data I/O available.

Asynchronous serial port.

On-chip hybrid and line driver.

Autobaud capability from 300 bps to 9600 bps.

Reduced external hardware support required with energy incoming ring detection.

1.1 Power Supply

Power is supplied to the 73M2901CE by the VPD and VPA pins. The 73M2901CE is designed for a

single +3.6 to +2.7 volt supply and for low power consumption (~30mW @ 3.0 volts). Ground is supplied

to the 73M2901CE by the VND and VNA pins.

The 73M2901CE has been designed with separated analog and digital supplies to insure the best

performance of the part by using separately filtered power supplies. It is recommended that separate

locally bypassed traces be used to apply power to the analog supply VPA and the digital supply VPD.

1.2 Low Power Mode

The Teridian 73M2901CE supports a low power standby mode. If the low power standby option is

enabled, the 73M2901CE will go into a power saving mode when idle.

While in this mode, the oscillator will be running and clocks will be supplied to the UART, timers and

interrupt blocks, but no clocks will be supplied to the CPU. Instruction processing and activity on the

internal busses is halted. Normal operation is resumed when an interruption such as assertion of DTR or

RING occurs, a character is sent to the 73M2901CE TXD input, or a reset occurs.

1.3 Analog Line / Hybrid Interface

The 73M2901CE provides a differential analog output (TXAP and TXAN) and a single-ended analog input

(RXA) with internal A/D and D/A converters. A driver is provided for an internal hybrid function.

The internal hybrid driver is capable of driving an external load matching impedance and a line-coupling

transformer. The internal hybrid/line driver senses the load and adapts itself to its requirements.

The 73M2901CE provides firmware control for a hook relay driver (RELAY) as well as interrupt support

for a ring detect opto-coupler (RING).

1.4 Interrupt pins

The external interrupt sources, DTR and RING, come from dedicated input pins of the same name.

DTR informs the 73M2901CE that the host has requested the 73M2901CE to perform a specific function.

The function of DTR can be changed by “AT” commands (described in full in the 73M2901CE AT

Command User Guide).
