DESCRIPTION
QCA4020 is an intelligent platform for the Internet of Things that contains a low-power
Wi-Fi(802.11 a/b/g/n 1x1), BLE 5.0 and Zigbee(802.15.4) connectivity protocols along with
SSL, enabling a low-cost, low-complexity system to obtain full-featured internet connectivity
and reliable information exchange.
QCA4020 device contains three processors:
The first processor, an ARM Cortex-M4F@ up to 128MHz is used as the application
processor. It runs the Qualcomm network stack as well as OEM application code.
Customer software runs under an RTOS such as ThreadX or FreeRTOS and so on.
Second processor, an ARM Cortex-M0@64MHz, which is utilized as the connectivity
processor for BLE and 802.15.4 subsystem
Third processor, CPU which is a dedicated processor to run the Wi-Fi dual band
function
PRODUCT FEATURES
The WCBN3516A module provides highly-integrated and flexible platform for developing
and evaluating products and applications based on QCA4020 SoC. WCBN3516A module can
be either used with development kit for software development or incorporated into OEM
products to enable rapid deployment of Wi-Fi connected system.
