The RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data rate up to 250 Kbps. The communication range can be increased by enabling a Forward Error Correction option, which is integrated in the modem. TRW-811S provides extensive hardware support for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication and wake-on-radio.The main operating parameters and the 64-byte transmit/receive FIFOs of TRW-811S can be controlled via an SPI interface. In a typical system, the TRW-811S will be used together with a microcontroller and a few additional passive components.
