PRELIMINARY
CYW20713
1. Overview
The Cypress CYW20713 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.
1.1 Major Features
Major features of the CYW20713 include:
■ Support for Bluetooth 4.0 + EDR, including the following options:
❐ Whitelist size of 25

❐ Secure simple pairing (SSP)
❐ Encryption pause resume (EPR)
❐ Enhance inquiry response (EIR)
❐ Link supervision time out (LSTO)
❐ Sniff subrating (SSR)
❐ Erroneous data (ED)
❐ Packet boundary flag (PBF)
■ Built-in low drop-out (LDO) regulators (2)
❐ 1.63 to 5.5V input voltage range
