5 Detailed Description
5.1 Overview
5.1.1 Device Features
5.1.1.1 WLAN
• 802.11b/g/n integrated radio, modem, and MAC supporting WLAN communication as a BSS station
with CCK and OFDM rates in the 2.4-GHz ISM band
• Auto-calibrated radio with a single-ended 50-Ω interface enables easy connection to the antenna
without requiring expertise in radio circuit design.
• Advanced connection manager with multiple user-configurable profiles stored in an NVMEM allows
automatic fast connection to an access point without user or host intervention.
• Supports all common Wi-Fi security modes for personal and enterprise networks with on-chip security
accelerators
• SmartConfig technology: A 1-step, 1-time process to connect a CC3100-enabled device to the home
wireless network, removing dependency on the I/O capabilities of the host MCU; thus, it is usable by
deeply embedded applications.
• 802.11 transceiver mode: Allows transmitting and receiving of proprietary data through a socket
without adding MAC or PHY headers. This mode provides the option to select the working channel,
rate, and transmitted power. The receiver mode works together with the filtering options.
5.1.1.2 Network Stack
• Integrated IPv4 TCP/IP stack with BSD socket APIs for simple Internet connectivity with any MCU,
microprocessor, or ASIC
• Support of eight simultaneous TCP, UDP, or RAW sockets
• Built-in network protocols: ARP, ICMP, DHCP client, and DNS client for easy connection to the local
network and the Internet
• Service discovery: Multicast DNS service discovery lets a client advertise its service without a
centralized server. After connecting to the access point, the CC3100 device provides critical
information, such as device name, IP, vendor, and port number.
5.1.1.3 Host Interface and Driver
• Interfaces over a 4-wire serial peripheral interface (SPI) with any MCU or a processor at a clock speed
of 20 MHz.
• Interfaces over UART with any MCU with a baud rate up to 3 Mbps. A low footprint driver is provided
for TI MCUs and is easily ported to any processor or ASIC.
• Simple APIs enable easy integration with any single-threaded or multithreaded application.
5.1.1.4 System
• Works from a single preregulated power supply or connects directly to a battery
• Ultra-low leakage when disabled (hibernate mode) with a current of less than 4 µA with the RTC
running
• Integrated clock sources
