CYW43353
Single-Chip 5G MAC/Baseband/Radio with Integrated
Bluetooth 4.1 for Automotive and Industrial Applications
General Description
The Cypress® CYW43353 single-chip device provides the highest level of integration for Automotive and Industrial connectivity
systems with integrated single-stream IEEE 802.11ac MAC/baseband/radio, Bluetooth 4.1. 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 up to 433.3 Mbps.
In addition, all the rates specified in 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, LNAs, and antenna diversity are also supported.
The CYW43353 offers an SDIO v3.0 interface for high speed 802.11ac connectivity. The Bluetooth host controller is interfaced over
a 4-wire high speed UART and includes PCM for audio.
The CYW43353 brings the latest mobile connectivity technology to automotive infotainment, telematics, rear seat entertainment, and
industrial applications. Offering automotive Grade 3 (-40C to +85C) temperature performance, the CYW43353 is tested to AECQ100
environmental stress guidelines and manufactured in ISO9001 and TS16949 certified facilities.
The CYW43353 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, GPS, and WiMAX) is provided via an external interface. As a result, enhanced overall quality for
simultaneous voice, video, and data transmission is achieved.
Cypress Part Numbering Scheme
Cypress is converting the acquired IoT part numbers from Cypress 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.
