15
I
Analog-to-Digital Converter input. The ADC is 12/8 bit and can use either
VCC or an internal/external voltage as reference.
ADC3: input
ADC2: input
ADC1: input / lower reference
ADC0: input / higher reference
GND 1, 6, 12, 16, 17 Power Ground signal
INT[1:0] 3, 4
I/O
Interrupt: The signal can be either level or edge trigged. When in power
down mode, the L-ZM2102 Z-Wave Module’s MCU can be woken up by
asserting the interrupt signal.

Master Out Slave In SPI interface: input in slave mode operation and
output in master mode operation.
PWM 4 I/O Pulse Width Modulator Output: Used for frequency variation applications.
RESET_N 2 I
Reset: Active low reset. The ZW0201 Single Chip has an integrated
Power-On-Reset and Brown-out detection circuitry.

SPI Clock: Can be used as either master SPI clock output or slave SPI
clock input.
TRIAC 13 I/O TRIAC Control: A triac controller is implemented in the ZW0201
Single Chip that can controls a triac on the Application Module like
light dimmer modules etc.
