CYW43455
Single-Chip 5G WiFi IEEE 802.11n/ac MAC/ Baseband/ Radio with Integrated Bluetooth 5.0 The Cypress CYW43455 single-chip device provides the highest level of integration for Internet of Things applications and handheld wireless system with integrated single-stream IEEE 802.11ac MAC/baseband/radio and, Bluetooth 5.0. In 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. The WLAN section supports the following host interface options: an SDIO v3.0 interface that can operate in 4b or 1b mode, a high-speed 4-wire UART, and a PCIe1Gen1 (3.0 compliant) interface. The Bluetooth section supports a high-speed 4-wire UART interface. Using advanced design techniques and process technology to reduce active and idle power, the CYW43455 is designed to address the needs of mobile devices that require minimal power consumption and compact size. It includes a power management unit which simplifies the system power topology and allows for direct operation from a mobile platform battery while maximizing battery life. The CYW43455 implements highly sophisticated enhanced collaborative coexistence hardware mechanisms and algorithms, which ensure that WLAN and Bluetooth collaboration is optimized for maximum performance. In addition, coexistence support for external radios (such as LTE cellular and GPS) is provided via an external interface. As a result, enhanced overall quality for simultaneous voice, video, and data transmission on a handheld system is achieved.
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.
