ADVANCE CYW43143 Single Chip IEEE 802.11 b/g/n MAC/PHY/Radio with USB/SDIO Host Interface The CYW43143 is a single-band, single-stream, IEEE 802.11n compliant, MAC/PHY/Radio system-on-a-chip with internal 2.4 GHz Power Amplifier (PA) and integrated T/R switch. The CYW43143 supports internal RX diversity by providing two antenna ports. The device enables development of USB or SDIO 802.11n WLAN clients that can take advantage of the high throughput and extended range of Cypress second-generation solution. The CYW43143 maintains compatibility with legacy IEEE 802.11b/g devices. State-of-the-art security is provided by industry standard support for WPA, WPA2 (802.11i), and hardware-accelerated AES encryption/decryption, coupled with TKIP, IEEE 802.1X support, and a WLAN Authentication and Privacy Infrastructure (WAPI) hardware engine. Embedded hardware acceleration enables increased system performance and reduced host-CPU utilization in both client and access point configurations. The CYW43143 also supports Cypress widely accepted and deployed WPS to easily secure WLAN networks. SDIO and USB wireless client modules for digital TVs, Blu-ray Disc players, set-top boxes, game consoles, and printers. 2 Supports the I S digital audio interface. Stand-alone wireless USB dongles and multimedia streaming boxes. Cypress Part Numbering Scheme Cypress is converting the acquired IoT part numbers from Broadcom to the Cypress part numbering scheme. Due to this conversion, there is no change in form, fit, or function as a result of offering the device with Cypress part number marking. The table provides Cypress ordering part number that matches an existing IoT part number. Table 1.
