CHAPTER 1. MODULE OVERVIEW
WBU053-LGABT is highly integrated module which features a low power 2x2 11 a/b/g/n
dual-band Wi-Fi subsystem and a Bluetooth subsystem. The Wi-Fi subsystem contains the 802.11
a/b/g/n radio, baseband, and MAC that are designed to meet both the low power and high
throughput application.
WBU053-LGABT has a 32-bit RISC MCU that handles Wi-Fi and Bluetooth tasks, and an ARM
Cortex-R4 MCU that could offload data frame processing in Wi-Fi host driver. The Bluetooth
subsystem contains the Bluetooth radio, baseband, link controller. It also uses the 32-bit RISC MCU
for the Bluetooth protocols.
