Hardware Connection Requirements
PS028511-0112
This section describes the required external hardware connection for the ZMOTION MCU
Series.
Pins are automatically configured to their required function when the PIR engine is initial-
ized via the EPIR_INIT macro.
See
showing the required connections.
The device can be operated in SINGLE PYRO Mode to support one pyroelectric sensor, or
DUAL PYRO Mode to support two pyroelectric sensors. Both of these modes can be
operated in NORMAL or LOW SCAN RATE modes.
Depending on the application, there can be up to 3 connection requirements supporting
these modes:
Pyroelectric Sensor (PIR Sensor).
to the ANA2 input of the ADC. The ADC is configured for differential, buffered mode by
Zilog’s PIR technology. The sensor signal should be connected directly to the ADC input
with no additional signal conditioning circuitry unless specified by the pyroelectric sensor
manufacturer.
