Working principle

The CYW20746A0KFBGT is a low-power, low-latency transceiver based on an advanced 802.15.4-compliant protocol. This device operates in the 2.4GHz ISM band and supports both Bluetooth Low Energy (BLE) and classic Bluetooth (BT) data rates. It offers radio coverage up to 6 meters and supports data rates up to 3 Mbps. The integrated antenna provides an increased directivity for improved communication range and increased throughput.

At the radio layer, the device contains a mix-mode transceiver and eight data channels in the 2.4 GHz ISM band, with a Carrier Sense Multiple Access (CSMA) protocol for reliable data transmission.

At the link layer, the CYW20746A0KFBGT implements Link Layer security, which provides strong 128-bit AES-CCM security for application data, as well as connection-oriented control and operation.

The device supports a low-rate Bluetooth data packet format for reliable data transmission over unreliable networks. It supports Low Energy Advertising (LEA) for data broadcast operations, and supports up to 128 simultaneous connections.

At the upper layers, the device implements the Host Controller Interface (HCI) for efficient integration with user-level Bluetooth protocol stacks. It also provides a host interface for logging debug data.
