CYW4373

Overview

1x1 Dual-band Wi-Fi 5 (802.11ac) + Bluetooth® 5.2 combo

Infineon’s AIROC™ CYW4373/CYW4373E/CYW43732 single-chip combo device features 1x1 dual-band 2.4 GHz and 5 GHz Wi-Fi 5 (802.11ac) and Bluetooth® 5.2. The “E” version offers extended temperature range (-40 to +85 °C) support and the CYW43732 offers support for dedicated LNA for the Wi-Fi and Bluetooth® subsystems. Included on-chip are 2.4 GHz and 5 GHz power amplifiers and low-noise amplifiers. All versions offer a USB hub and SDIO Wi-Fi host interfaces with the CYW4373E also offering PCIe.
