Table 12 External headers (P6) – pin description
Pin no. Signal name
1 V_PTAT_S&H_EN
2 BB1_EN
3 V_DAC_1
Notes:
1. Pins 5, 6 of header P2 are not connected to any signal.
2. Pins 1, 3, 8 of header P3 are not connected to any signal.
3. Pins 1, 4, 6, 7, 8 of header P4 are not connected to any signal.
4. Pin 6 of header P5 is not connected to any signal.
The pin headers enhance the functionality of the module significantly. They enable probing the analog outputs
of the sensor module and also probing various other signals provided to the IC. In principle, the accessibility of
several pins on the radar IC and the IF signals available via the external pin headers enable interfacing the
module with an external signal processor.
