Preliminary W91030
Publication Release Date: May 1997
- 13 - Revision A1
capacitors are charged. The microcontroller should therefore ignore the interrupt from these source
until the capacitors are charged up (in M-mode). The microcontroller can examine the RNGON and
ALGO pins and wait until these signals are inactive during a power on interrupt. In C-mode, the
interrupt occurs only after the capacitors have been charged, and will wait until FSKE is set high.
It is possible to clear the ALGO pin and its interrupt quickly by setting the SLEEP pin high. In the
sleep mode, the ALGO pin is forced low and the charge switch in Figure 7-4 will turn on, forcing the
capacitor to charge up rapidly.
Sleep Mode
The W91030 can go into a sleep mode by setting SLEEP high, resulting in reduced power
consumption. In this mode, the gain control op-amp, oscillator and all internal circuits, except the ring
detector are disabled. The RNGDI, RNGRC and RNGON pins are not affected, so the device can still
react to call arrival indicators and activate an interrupt to wake up the microcontroller. The sleep
mode can be disabled by the microcontroller.
Crystal Oscillator
The operation frequency of the W91030 is 3.579545 MHz. Crystal oscillators, ceramic resonators or
other clock sources can be used. A crystal oscillator or ceramic resonator can be directly connected
to the OSCI and OSCO pins without the need for external components. If other clock sources are
used, the OSCI pin should be driven by a clock source and the OSCO pin used to drive other external
clocked devices, or left open. Figure 7-9 shows some applications.
