PRELIMINARY
CYBT-243068-02
CYBT-243069-02
Mouse Quadrature Signal Decoder
The CYBT-243068-02/CYBT-243069-02 includes one double-axis and one single axis quadrature decoders. There are two input lines
for each axis and a programmable control signal that can be active high or low.
The application can access the quadrature interface via the driver included in the firmware.
ADC Port
The CYBT-243068-02/CYBT-243069-02 includes a Σ-Δ ADC designed for audio and DC measurements. The ADC can measure the
voltage on 13 (CYBT-243068-02) GPIOs (P0, P1, P8, P10, P12-P15, P17, P28, P29, P32, P37) and 15 (CYBT-243069-02) GPIOs
(P0, P1, P8-P15, P17, P28, P29, P32, P37). When used for analog inputs, the GPIOs must be placed in digital input disable mode to
disconnect the digital circuit from the pin and avoid leakage. The internal bandgap reference has ±5% accuracy without calibration.
Calibration and digital correction schemes can be applied to reduce ADC absolute error and improve measurement accuracy in Direct
Current (DC) Mode.
The application can access the ADC through the ADC driver included in the firmware.
The following CYBT-243068-02/CYBT-243069-02 module solder pads can be used as ADC inputs:
■ Pad 4: P29, ADC Input Channel 10
■ Pad 5: P32, ADC Input Channel 7
■ Pad 7: P37, ADC Input Channel 2
■ Pad 8: P28, ADC Input Channel 11
■ Pad 9: P0, ADC Input Channel 29
■ Pad 10: P1, ADC Input Channels 28
■ Pad 11: P10, ADC Input Channel 25
■ Pad 12: P13, ADC Input Channel 22
■ Pad 14: P12, ADC Input Channel 23
■ Pad 15: P11 (CYBT-243069-02), ADC Input Channels 24
■ Pad 16: P9 (CYBT-243069-02), ADC Input Channels 26
■ Pad 17: P14, ADC Input Channels 21
■ Pad 18: P17, ADC Input Channels 18
■ Pad 26: P15, ADC Input Channels 20
■ Pad 27: P8, ADC Input Channels 27
GPIO Port
The CYBT-243068-02/CYBT-243069-02 has a maximum of 22 GPIOs. All GPIOs support the following:
■ Programmable pull-up/down of approximately 45 kΩ.
■ Input disable mode, allowing pins to be left floating or analog signals connected without risk of leakage.
■ Source/sink 8 mA at 3.3 V and 4 mA at 1.8 V.
■ P26/P27/P28/P29 can sink/source 16 mA at 3.3 V and 8 mA at 1.8 V.
Most peripheral functions can be assigned to any GPIO using the ModusToolbox Device Configurator. For details on the functions
that are assignable via the ModusToolbox Device Configurator, refer to Table 5.
The following list details the GPIOs that are available on the CYBT-243068-02/CYBT-243069-02 module:
■ P0-P6, P8-P15, P17, P26-P29, P32, and P37
