General description

The Infineon AIROC™ CYW20829 is a high-performance, ultra-low-power and “Secure” MCU + Bluetooth®

LE

platform, purpose-built for IoT applications. It combines a high-performance microcontroller with Bluetooth®

LE (5.4) connectivity, high-performance analog-to-digital conversion audio input, I2S/PCM, CAN, LIN for

automotive use cases and other standard communication and timing peripherals. CYW20829 employs high

level of integration to minimize external components, reducing the device footprint and costs associated with

implementing Bluetooth®

Low Energy solutions. AIROC™ CYW20829 is the optimal solution for wireless input

devices, remotes, keyboards, joysticks, Bluetooth®

Mesh, automotive, asset tracking, and Bluetooth®

LE IoT

applications that need 10 dBm RF output power such as lighting and home automation.
