The WBZ451H module supports all available interfaces, excluding specific pins on the PIC32CX1012BZ25048 SoC.
- PB1 is configured as the bypass mode control (CPS) for the Front-End Module (FEM) (SKY66114-11), ensuring that the CPS disables when the target power is ≥ -1 dBm and enables when the target power is less than -1 dBm.
- PA10 synchronizes with the TX signal and connects with both CTX and CHL for transmitting High-power mode.
- PA9 synchronizes with the RX signal and connects with CRX for the Receive mode.
- CSD is pulled high with fixed hardware control.
The RF specification of the WBZ451H module, a 48-pin QFN package that seamlessly integrates LPA/MPA capabilities with an external FEM design, culminates in an impressive +20 dBm output power.
