The ADF7022 is an io-homecontrol-compliant RF transceiver with features of low power, high performance, and low IF. It fully integrates the Layer 1, Layer 2, and time-critical elements of Layer 3 of the io-homecontrol protocol. It supports master, slave, and beacon modes, with automatic io-homecontrol channel scan, automatic CRC, preamble, start byte insertion/check, UART data encoding, and more. Additionally, it has features like low power modes, automatic address filtering, autonomous packet handling, etc., significantly increasing battery life.
The ADF7022 is an io‑homecontrol‑compliant RF transceiver designed for low‑power wireless communication in home automation and building control applications. It integrates protocol handling, automatic channel scanning, CRC, preamble insertion, UART encoding, and autonomous packet processing without host MCU intervention.
Key features include very low current consumption in various modes, programmable output power up to 13.5 dBm, dual‑PA antenna diversity, on‑chip ADC and temperature sensor, and a flexible SPI interface. The device is supplied in a 5 mm × 5 mm 32‑lead LFCSP package and operates from 1.8 V to 3.6 V.
