产品名称：CY43455 wifi模块

版本：01

introduces the pioneer of the IEEE 802.11 a/b/g/n/ac WIFI with Bluetooth 4.2 combo SDIO and UART Stamp Module --- AW-CM256SM. The AW-CM256SM IEEE 802.11 a/b/g/n/ac WIFI with Bluetootth 4.2 combo 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 4.2 and provides a complete 2.4GHz Bluetoooth system which is fully compliant to Bluetooth 4.2 and v2.1 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 combo stamp module Compliant with the IEEE 802.11a/b/g/n/ac standard, AW-CM256SM uses Direct Sequence Spread Spectrum (DSSS), Orthogonal Frequency Division Multiplexing (OFDM), BPSK, QPSK, CCK and QAM baseband modulation technologies. Compare to 802.11n technology, 802.11ac standard makes big improvement on speed and range. AW-CM256SM module adopts Broadcom solution. The module design is based on the Broadcom BCM43455 single chip
