PIN DESCRIPTION
SYMBOL PIN I/O
PIN DESCRIPTION
OSCI
1
I 100 kHz crystal input.
OSCO
2
O 100 kHz crystal output.
GND
3
I Ground power.
TCTL2
4
O RF control pin. Inversion output of QC2.
D0
5
I Demodulated data input bit0(LSB).
D1
6
I Demodulated data input bit1(MSB).
QC2
7
O Receiver quick charge 2 signal enable. Active high/low is dependent
on QC2L option bit.
TCTL1
8
O RF control pin.
QC1
9
O Receiver quick charge 1 signal enable. Active high/low is dependent
on QC1L option bit.
RFEN
PLEN
10
O Receiver power control. Active high/low is dependent on RFENL option
bit.
11
O PLL frequency synthesizer power control. Active high/low depends on
PLENL option bit. µC must program the freq. synthesizer counter while
PLEN inactive. W93910 internal channel will be decided during PLEN
active edge.
