Description

TiWi-SL are the industry's first industrial temp-rated 802.11 b/g Wi-Fi modules. They have been designed for simple connectivity to the industry's most popular microcontroller platforms. It utilizes Texas Instruments' CC3000 SimpleLink™ technology to move nearly all the functions required for Wi-Fi off the host processor and onto the module.

Features

  • Self-contained solution with Wi-Fi driver, security supplicant and TCP/IP stack all on-module
  • Small host footprint -- as low as 6KB Flash, 3KB RAM
  • Low memory footprint enables Wi-Fi connectivity with MCUs
  • Low MIPS/CPU overhead
  • Extremely simple API, primarily BSD socket; about 35 total APIs
  • Universal IP connectivity enables Wi-Fi anywhere
  • Quick Wi-Fi implementation without previous Wi-Fi or RF experience
  • Quickly portable to any low-cost, low-power MCU platform
  • Enables headless Wi-Fi with TI patented "First Time Config"
  • Begin development with any MCU using LSR's TiWi-SL EM Board (450-0089) or with TI's MSP430 FRAM kit
