ESP8089 Datasheet PDF – Highly-integrated 2.4G Wi-Fi SoC

Part Number: ESP8089

Function : High Performance Wireless SoC

Package: QFN32 Package ( 5x5mm )

Manufacturer: Espressif ( )




The device is a low-power Wi-Fi System-on-Chip (SoC) made by Espressif Systems. It is a highly integrated device that integrates a CPU, flash memory, RAM, Wi-Fi and a peripheral interface, and is designed for Internet of Things (IoT) applications.

The ESP8089 offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to off-load all Wi-Fi networking functions from another application processor.

When ESP8089 hosts the application, it is usually the only application processor in the device, with the user’s applications stored in an internal/external Flash. Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any microcontroller-based design with simple connectivity through the SPI/SDIO interface or the CPU AHB bridge interface
