1.2 Product Overview

KERTONG to announce a low-cost and low-power consumption th e co mbo module

of K019-CW43-DW

model

which has all of the WiFi(IEEE802.11a/b/g/n/ac), Bluetooth (5.0)

functionalities. And the highly integrated module

makes the possibilities of web browsing Mini

audio; Wireless projector; TV Box; Bluetooth POS.ect and other applications. With seamless

roaming capabilities and advanced

security, also could interact with different vendors’ 802.11

a/b/g/n/ac Access Points in the wireless

LAN.

This K019-CW43-DW module using the chipset from CYPRESS’s the CYW43455 with

IEEE 802.11ac mode, the WLAN operation supports rates of MCS0–MCS9 (up to 256 QAM)

in 20 MHz, 40 MHz, and 80 MHz channels for data rates of up to 433.3 Mbps. All rates

specified in the IEEE 802.11a/b/g/n are supported. Included on-chip are 2.4 GHz and 5 GHz

transmit amplifiers and receive low-noise amplifiers. Optional external PAs and LNAs are also

supported. WLAN section supports the following host interface options: an SDIO v3.0 interface

that can operate in 4b or 1b mode, a highspeed 4-wire UART, and a PCIe Gen1 (3.0 compliant)

interface. The Bluetooth section supports a high-speed 4-wire UART interface.

The K019-CW43-DW module complies with IEEE 802.11 a/b/g/n/ac standard and it

can achieve up to a speed of 433.3Mbps with single stream in 802.11ac draft to connect to

the wireless LAN. The integrated module provides SDIO interface for Wi-Fi, UART / PCM

interface for Bluetooth.
