1. Introduction
6223A-SRD is a small size and low profile of WiFi + BT Combo module with LGA (Land-Grid Array)
footprint, board size is 12mm*12mm with module thickness of 2mm. It can be easily manufactured on
SMT process and highly suitable for tablet PC, ultra book, mobile device and consumer products. It
provides SDIO interface for WiFi to connect with host processor and high speed UART interface for BT. It
also has a PCM interface for audio data transmission with direct link to external audio codec via BT
controller. The WiFi throughput can go up to 150Mbps in theory by using 1x1 802.11n b/g/n SISO
technology and Bluetooth can support BT2.1+EDR/BT3.0 and BT4.2.
6223A-SRD uses highly integrated WiFi/BT single chip based on advanced COMS process. 6223A-SRD
integrates whole WiFi/BT function blocks into a chip, such as SDIO/UART, MAC, BB, AFE, RFE, PA,
EEPROM and LDO/SWR, except fewer passive components remained on PCB.
This compact module is a total solution for a combination of Wi-Fi + BT technologies. The module is
specifically developed for Smart phones and Portable devices.
