Overview

The ESP8089 offers a complete and self-contained Wi-Fi networking solution. When

serving as a Wi-Fi adapter, ESP8089 can work with any microcontroller-based systems to

achieve wireless connectivity through the SPI/SDIO interface.

ESP8089 allows direct connection to cellular baseband and application processors via SPI/

SDIO or memory-mapped parallel interfaces. Its built-in processing and storage capabilities

allow it to integrate with the host platform, with minimal development upfront and loading

during runtime. ESP8089 is highly-integrated, including the antenna switch balun and

power management converters, reducing the external circuitries. The entire solution,

including the front-end module, requires minimal PCB area.

The ESP8090-based systems have the following advanced features:

•

fast sleep/wake context switching for energy-efficient VoIP,

•

adaptive radio biasing for low-power operation,

•

advanced signal processing, and

•

spur cancellation and radio co-existence features for cellular/Bluetooth/802.11

interference mitigation.
