Single-chip low power 802.11n WLAN and BLE module
The CDW-B78720C-XX series from Cdtech and available from Tecona are highly integrated single-chip low power 802.11n wireless LAN (WLAN) network controllers.

Measuring a mere 22- x 15- x 2.5-mm, the CDW-B78720C-XX series combine a KM4 MCU, WLAN MAC, a 1T1R, WLAN baseband, RF, and Bluetooth in a single chip. Bluetooth covers BLE4.2, BLE5.0 and BLE Mesh specifications, while the 1T1R WLAN encompasses 802.11b/g/n.

The chip also provides a bunch of configurable GPIOs which are configured as digital peripherals for different applications and control usage.

The CDW-B78720C-XX series integrate internal memories for complete WIFI protocol functions. The embedded memory configuration also enables simplified application development.

The devices carry FCC and WiFi alliance certifications. Both DIP and SMT assembly methods are supported.
