Broadcom targets 8/16-bit MCU IoTs with new WiFi chip

Broadcom has just introduced its BCM4390 system-on-a-chip (SoC) for embedded 8/16 bit based designs that combines WiFi with an extensive programming API and SDK.

The BCM4390 is part of Broadcom's Wireless Internet Connectivity for Embedded Devices (WICED) portfolio targeting the rapidly expanding “Internet of Things” market.

According to Brian Bedrosian, Broadcom's Senior Director for Embedded Wireless in Broadcom's Wireless Connectivity Combo Group, consumers are demanding higher levels of connectivity than ever before whether in the home or on the go, with 30 billion connected devices predicted by ABI Research to be in the market by 2020.

“Adding Wi-Fi to previously unconnected devices can be a complicated process that drives up cost and increases power usage,” he said. ”Power is particularly challenging for resource-limited, battery operated products.

The WICED BCM4390 SoC is designed for 8 and 16 bit Microcontroller systems and delivers Wi-Fi connectivity to low-power and battery-powered devices with a battery voltage range from 2.3V to 5.5V.

In order to support 8 and 16bit designs, the WiFi chip has been design to ease implementation of a real-time operating system (RTOS) and a network stack on the application CPU. It enables authentication and connection to cloud services with a “self-hosted” software stack.
