Single Pyroelectric Sensor
Figure 11
Control MCU Family with a single Pyro Electric sensor. The interface to the pyroelectric sensor
is via the dedicated input ANA2 (pin 2). V
The status LED is driven by pin 19 (PC3/COUT) which is normally configured as a GPIO by
the application to control the state of the LED. This pin provides a programmable constant
current sink specifically for LED drive without using an external resistor. Pin 15 is dedicated as
the Debug pin and is connected to pin 4 of the Debug Header. Pin 14 is set up for the Reset
function, but may also be used as PD0 (general purpose I/O) as the application requires. Pull-
up resistors (10K) are provided on the Debug and Reset signals as required for the Debug
interface. All other signals may be used as needed. The power supply design is left to the
application needs.
