13.5 Example of Application Circuit 4
is an example of application circuit only for receiving controlled by MCU and EEPROM.
Fig 13-5
(For receiving only / 5V Use)
VDD
MCU
- Fig 13-5 is the EEPROM Mode and external EEPROM I/O is connected to SPI control pins of TC32306FTG,
- Fig 13-5 is 5V Use. For 3V Use, change the voltage supply connections by referring Fig 13-1.
- Do not connect DC voltage except ground to RF_IN pin.
- PA_OUT pin is open.
- MCU controls RESET pin.
- MCU controls ENB pin, RX_SW pin and TX_SW pin to set configuration of EEPROM.
- MCU accepts a signal from DET_TMONI1 pin as an interrupt signal.
- MCU monitors RSSI_OUT pin signal.
- In EEPROM Mode, this IC doesn't prepare antenna switch control.
- About EEPROM pin termination, see that manual.
- About resistors, capacitors and coils values in the circuit, consider referring to the evaluation circuit of section 13.1.
