AMIS-52100
Low-Power Transceiver with Clock and Data Recovery
Data Sheet
9.11 Alternative Wake-Up
Figure 19: Wakeup Circuits
The AMIS-52100 will wake from a low power mode upon the reception of RF energy, an application wakeup time out or when signaled
by an external controller. The low power mode is when the RF circuits are shut off, the crystal oscillator is shut off, the CLKOUT circuits
are shut off and only the RC oscillator and wakeup divider chain are running. When the AMIS-52100 receiver detects energy and wakes
up, the RX/TX pin is set low while the I
CDATA and I
CCLK pins are allowed to remain pulled high. When the application wakeup timer
wakes the AMIS-52100 to inform the external controller that tasks need to be performed, the TX/RX and I
CDATA pins are set low
while the I
CCLK pin is allowed to remain high. The TX/RX pin can be used to alert the external controller that a wake up occurred in
the AMIS-52100. Then the external controller can interrogate the I
C pins to determine what caused the wake up to occur. The external
controller can also cause the AMIS-52100 to wake up by setting both the I
CDATA and I
CCLK lines low. These functions are shown in
the following Table 30.
