Description

Functionality

20 IRQ

Digital Output

Active Low Interrupt Request.

Open drain device.

Programmable 40

kΩ internal pull-up.

Interrupt can be

serviced every 6 µs

with <20 pF load.

Optional external

pull-up must be >4

kΩ.

26 XTAL1

Input

Crystal Reference oscillator input.

Connect to 16 MHz

crystal and load

capacitor.

27 XTAL2

Input/Output

Crystal Reference oscillator output

Note: Do not load this pin by using it as a 16 MHz

source. Measure 16 MHz output at Pin 15,

CLKO, programmed for 16 MHz. See the

MC13192 Reference Manual for details.

Connect to 16 MHz

crystal and load

capacitor.

28 VDDLO2 Power Input

LO2 VDD supply. Connect to VDDA externally.

29 VDDLO1 Power Input

LO1 VDD supply. Connect to VDDA externally.

30 VDDVCO Power Output

VCO regulated supply bypass.

Decouple to ground.

31 VBATT

Power Input

Analog voltage regulators Input. Connect to Battery. Decouple to ground.

32 VDDA

Power Output

Analog regulated supply Output. Connect to directly

VDDLO1 and VDDLO2 externally and to PAO±

through a frequency trap.

Note: Do not use this pin to supply circuitry external to

the chip.

Decouple to ground.

EP Ground

External paddle / flag ground.

Connect to ground.

1 The transceiver GPIO pins default to inputs at reset. There are no programmable pullups on these pins. Unused GPIO pins

should be tied to ground if left as inputs, or if left unconnected, they should be programmed as outputs set to the low state.

2 During low power modes, input must remain driven by MCU.

3 By default MISO is tri-stated when CE is negated. For low power operation, miso_hiz_en (Bit 11, Register 07) should be set

to zero so that MISO is driven low when CE is negated.
