Wi-Fi Transceiver Chip

ASR553X is a low-power, high-performance, highly integrated 2x2 MIMO transceiver SoC supporting IEEE802.11 b/g/n and BLE 5.1 protocols. This chip integrates a low-power, high-performance RF transceiver, ARM China STAR-MC1 processor, a rich set of peripherals, and power management module including DC-DC and LDO. ASR553X provides a convenient and fast BLE networking, currently only in 6 seconds(optimization is ongoing). Two fully integrated RF transceivers include power amplifiers, on-chip switches, low noise amplifiers and more. They can be used in terminals such as MIFI, wireless NICs, conventional TVs, etc.,or paired with AP chips for CPE devices.
