Example Application Schematics

Z8FS040xSB20EG - (8 Pin)

Figure 10 shows an example circuit for the 8 pin device of the ZMOTION

TM Detection and

Control MCU Family. The interface to the pyroelectric sensor is via the dedicated input ANA2

(pin 5). The status LED is driven by pin 6 which is normally configured as a GPIO by the

application to control the state of the LED. Pin 2 is used as the debug input to the chip, but can

be used for other functions as required. Pin 4 is set up for the Reset function, but may also be

used for other functions as the application requires. Pull-up resistors (10K) are provided on the

Debug and Reset signals as required for the Debug interface. The signals on pins 3 and 7 can

be used as needed. The power supply design is left to the application needs.

In Dual Pyro mode, the second Pyroelectric sensor is connected to Pin 3 (ANA3). All other

connections remain the same.
