CHAPTER 1. MODULE OVERVIEW

The Foxconn WBU053-LGA is a highly integrated module which features a low power 2x2

dual-band Wi-Fi subsystem. The Wi-Fi subsystem contains the 802.11a/b/g/n radio, baseband, and MAC that are designed to meet both the low power and high throughput application.

WBU053-LGA has a 32-bit RISC MCU that handles Wi-Fi, and an ARM Cortex-R4 MCU that

could offload data frame processing in Wi-Fi host driver.

1-1 Key Characteristic
