CC2642R vs CYW20820: Industrial BLE Sensor Hub vs Automotive Dual-Mode Bluetooth


The TI CC2642R and Infineon CYW20820 both carry Bluetooth radios but serve entirely different markets. CC2642R is TI's ultra-low-power BLE 5.2 sensor hub for industrial and medical IoT — consumer or industrial, battery-powered, BLE-only. CYW20820 is Infineon's (formerly Cypress) AEC-Q100-qualified automotive dual-mode Bluetooth SoC supporting both Classic Bluetooth (for audio) and BLE (for IoT telemetry) in harsh vehicle environments.




Overview


CC2642R is a 48 MHz Cortex-M4F with 352 KB Flash, 80 KB RAM, BLE 5.2, Sensor Controller Engine (autonomous ADC/I2C/SPI at ~0.6 µA), ~1.4 µA standby, and industrial temperature variants (-40°C to +85°C). A focused, efficient BLE-only design for long-life sensor nodes.


CYW20820 integrates an Arm Cortex-M4 application core, dual-mode Bluetooth 5.0 (Classic BR/EDR + BLE), 256 KB RAM, 512 KB Flash, a hardware audio subsystem (I2S, PCM, hardware SBC and CVSD/mSBC codecs for voice), extended temperature (-40°C to +105°C), and AEC-Q100 Grade 1 qualification. It is designed for automotive head units, hands-free kits, and telematics control units.




Key Differences


    

  • Bluetooth Classic: CYW20820 supports BR/EDR for A2DP audio and HFP hands-free calling; CC2642R is BLE-only.
    • 

  • Automotive qualification: CYW20820 carries AEC-Q100 Grade 1 and extended temperature to +105°C; CC2642R has industrial variants to +85°C but no AEC-Q100.
    • 

  • Sensor Controller: CC2642R's SCE provides autonomous peripheral sampling at ~0.6 µA; CYW20820 has no equivalent.
    • 

  • Power: CC2642R ~1.4 µA standby is significantly lower than CYW20820's automotive-optimized power profile (designed for connected operation, not coin-cell).
    • 

  • Audio: CYW20820 has hardware audio processing (SBC, CVSD, mSBC); CC2642R has no audio hardware.
    • 

  • SDK: CC2642R uses TI SimpleLink SDK; CYW20820 uses Infineon ModusToolbox + WICED Bluetooth SDK.
    • 

  • Application domain: CC2642R is consumer/industrial IoT; CYW20820 is automotive infotainment and telematics.
    • 





Use Cases


Choose CC2642R for coin-cell or small battery-powered BLE sensor nodes in industrial, medical, or consumer IoT applications where ultra-low standby current and Sensor Controller autonomous sampling are critical advantages.


Choose CYW20820 for automotive applications — vehicle Bluetooth handsfree systems, in-car audio streaming, automotive asset tracking dongles, and telematics units — where AEC-Q100 qualification, +105°C temperature rating, Classic Bluetooth audio profiles, and hardware voice codec processing are mandatory requirements.




Verdict


CYW20820 is purpose-built for automotive Bluetooth where dual-mode Classic + BLE, AEC-Q100 qualification, and extended temperature define the product requirements. CC2642R is purpose-built for ultra-low-power IoT sensor endpoints where the Sensor Controller autonomously reads sensors for years on a small battery. The two chips do not compete — they operate in different market segments with different certification requirements and power envelopes.
