PRELIMINARY
CYW20710
1. Overview
The Cypress CYW20710 complies with the Bluetooth Core Specification, version 4.0 and is designed for use with a standard Host
Controller Interface (HCI) UART. The combination of the Bluetooth Baseband Core (BBC), a Peripheral Transport Unit (PTU), and an
ARM®-based microprocessor with on-chip ROM provides a complete lower layer Bluetooth protocol stack, including the Link Controller
(LC), Link Manager (LM), and HCI.
