AIROC™ CYW20829 Bluetooth® LE SoC
The perfect combination of low power and high performance

AIROC™ CYW20829 Bluetooth® LE SoC

The AIROC™ CYW20829 Bluetooth® LE SoC is a Bluetooth® 5.3 core spec-compliant device for IoT, smart home and industrial applications. With the right combination of low power and performance, AIROC™ CYW20829 is designed to support the entire spectrum of Bluetooth® Low Energy use cases for home automation, sensors, lighting, Bluetooth® Mesh, remote controls and any other Bluetooth® LE-connected IoT application.

With Infineon's AIROC™ CYW20829, designers won't have to choose between low power and high performance. The device has been designed from the ground up with efficient peripheral design, low leakage silicon with scalable and efficient MIPS, and a low power Bluetooth® radio. The solution offers superior RF performance for reliable, robust connections, enabling the best user experience in the latest smart, connected devices.

AIROC™ CYW20829 integrates a power amplifier with 10 dBm of transmit output power and has receive sensitivity of -98.5 dBm for LE and -106 dBm for LE-LR 125 Kbps for the best link budget in the AIROC™ Bluetooth® portfolio. The best-in-class RF performance offers reliable, robust connectivity without compromising low power - making the CYW20829 ideal for a wide range of applications in smart home, smart building, medical, industrial, mesh, and hid (keyboard, mouse, remote control).

The CYW20829 is the first Infineon AIROC™ Bluetooth® system on chip to use the ARM® Cortex® M33. The Bluetooth® LE subsystem is architected for low current consumption with a highly optimized radio and an ARM® Cortex® M33 core focused as the Bluetooth® controller. A second ARM® Cortex® M33 with a floating-point unit is dedicated for customer applications and can be clocked up to 96 MHz to provide high performance compute at low power. The application sub-system is highly integrated with configurable serial communication blocks that can be turned into UART/I2C/SPI as needed, multiple timer/counter pulse-width modulators, I2S, PDM, CAN and LIN interfaces. Security is built into the platform architecture with a ROM based root of trust, a TRNG, eFuse for custom keys and cryptography acceleration. For added flexibility AIROC™ CYW20829 also supports XIP from external flash as well as encryption on the fly for content on the flash.

The AIROC™ CYW20829 is supported by ModusToolbox™ software. ModusToolbox™ is a collection of easy-to-use software and tools enabling rapid development of Bluetooth® enabled IoT solutions. Brainstorm new ideas and get support for the AIROC™ Bluetooth® and Multi-protocol system on chip family via the Infineon Developer Community with direct access to online applications support engineers.
