YL43455 IEEE 802.11a/b/g/n/ac Wireless LAN, Bluetooth and FM receiver Combo Stamp Module
General Description
The YL43455 IEEE 802.11 a/b/g/n/ac SDIO Wi-Fi with Bluetooth and FM receiver
combo stamp module is a highly integrated wireless local area network (WLAN)
solution to let users enjoy the digital content through the latest wireless
technology without using the extra cables and cords. It combines with
Bluetooth and provides a complete 2.4GHz Bluetooth system that is fully
compliant to Bluetooth and SDIO v3.0 that supports EDR of 2Mbps and 3Mbps for
data and audio communications. It enables a high-performance, cost-effective,
low-power, compact solution that easily fits onto the SDIO and UART stamp
module.
Compliant with the IEEE 802.11a/b/g/n/ac standard, YL43455 uses Direct
Sequence Spread Spectrum (DSSS), Orthogonal Frequency Division Multiplexing
(OFDM), BPSK, QPSK, CCK and QAM baseband modulation technologies.
A high level of integration and full implementation of the power management
functions specified in the IEEE 802.11 standard minimize system power
requirements by using YL43455.
YL43455 module adopts BCM43455 single chip solution. The module design is
based on the BCM43455 solution.
