CYW54591RKUBGT

CYW54591RKUBGT is a CYW5459x complete dual-band (2.4GHz and 5GHz) Wi-Fi 5 2×2 MIMO MAC/PHY/Radio system-on-chip. This Wi-Fi 5 single chip device provides a high level of integration with a dual-stream IEEE 802.11ac MAC/baseband/radio and Bluetooth 5.1. In IEEE 802.11ac mode, the WLAN operation supports rates of MCS0–MCS9 (up to 256 QAM) in 20MHz, 40MHz, and 80MHz channels for data rates up to 867Mbps. In addition, all the rates in IEEE 802.11a/b/g/n are supported. Included on-chip Wi-Fi 5 are the 2.4GHz and 5GHz transmit power amplifiers and receive low-noise amplifiers. The WLAN operation supports 2x2 MIMO operations as well as two fully simultaneous SISO channels; one in 2.4GHz and the other in 5GHz enabling dual-band real simultaneous dual-band (RSDB) operation. For the WLAN section, the device interfaces to a host SoC processor through a PCIe v3.0-compliant interface running at Gen1 speed, and an SDIO v3.0 interface that can operate in 4b or 1b modes.
