WizFi220 (WiFi)

Description:

The WizFi220_CA is an ultra low power serial to WiFi module with power amplifier and on-board Chip Antenna. The module provides serial UART interface which enables connection to any embedded design utilizing and 8/16/32-bit micro-controller via simple commands. The module supports data rates up to 11 Mbps, and is compliant with 802.11b. The Serial to Wi-Fi embedded software allows devices and appliance manufacturers to easily add WiFi capabilities to their products with minor impact on the host micro-controller firmware. The WizFi220 provides all the hardware and software necessary to quickly set up a serial (UART) based link to a PC or external micro-controller.

Features:

• Brings Wi-Fi connectivity to any device with a micro-controller and serial HOST interface (UART)
• Quick Booting Time : under 20mSec
• Minimal Serial to Wi-Fi “driver ” footprint on host microcontroller and minor changes to existing host MCU firmware
