The USB connections D
+
and D
remain powered and logically connected to the
USB bus. If a crystal oscillator is used, powering down during ‘suspend’ is managed
by the internal logic of ISP1181. When using an external oscillator on pin XTAL1, a
stable logic 1 level must be applied during ‘suspend’ state.
Figure 7
shows a typical bus-powered modem application using ISP1181 in
powered-on mode. The SUSPEND output is connected to the reset input (RST) of the
8031 microcontroller via an external inverter. This allows a ‘resume’ condition to wake
up the 8031 from power-down mode. The ISP1181 is woken up via the USB bus
(global resume) or by the ring detection circuit on the telephone line.
11.1.2
Powered-off application
In powered-off application (PWROFF = 1 in the Hardware Configuration Register) the
supply of the CPU and other parts of the circuit is removed during ‘suspend’ state.
The SUSPEND output is active HIGH during ‘suspend’ state, making it suitable as a
power switch control signal, e.g. for an external oscillator.
Input pins of ISP1181 are pulled to ground via the pin buffers. Outputs are made
three-state to prevent current flowing in the application. Bi-directional pins are made
three-state and must be pulled to ground externally by the application. The power
supply of external pull-ups must also be removed to reduce power consumption.
