1. General Description
BL-M7603NU4 is a highly integrated Wi-Fi single chip which support 300 Mbps PHY rate. It fully complies with
IEEE802.11n and IEEE802.11b/g standard, offering feature-rich wireless connectivity at high standard, and
delivering reliable, cost-effective throughput from an extended distance.
Optimized RF architecture and baseband algorithms provide superb performance and lower power consumption.
Intelligent MAC design deploys a high efficient DMA engine and hardware data processing accelerators which
offloads the host processor.
2. Applications
MID, networking camera, STB GPS, E-book, Hard disk player, Network Radios, PSP and other device
which need be supported by wireless networking.
