5 Detailed Description

5.1 Overview

5.1.1 Module 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 CC3100MOD-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 CC3100MOD 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 7 µA with the RTC running
  • Integrated clock sources

5.3 Wi-Fi Network Processor Subsystem

The Wi-Fi network processor subsystem includes a dedicated ARM MCU to completely offload the host MCU along with an 802.11 b/g/n radio, baseband, and MAC with a powerful crypto engine for a fast, secure WLAN and Internet connections with 256-bit encryption. The CC3100MOD supports station, AP, and Wi-Fi Direct modes. The module also supports WPA2 personal and enterprise security and WPS 2.0. The Wi-Fi network processor includes an embedded IPv4 TCP/IP stack.

5.4 Power-Management Subsystem

The CC3100 power-management subsystem contains DC-DC converters to accommodate the differing voltage or current requirements of the system. The module can operate from an input voltage ranging from 2.3 V to 3.6 V and can be directly connected to 2xAA Alkaline batteries.

The CC3100MOD is a fully integrated module based WLAN radio solution used on an embedded system with a wide-voltage supply range. The internal power management, including DC-DC converters and LDOs, generates all of the voltages required for the module to operate from a wide variety of input sources. For maximum flexibility, the module can operate in the modes described in the following sections.

5.4.1 VBAT Wide-Voltage Connection

In the wide-voltage battery connection, the module is powered directly by the battery. All other voltages required to operate the device are generated internally by the DC-DC converters. This scheme is the most common mode for the device as it supports wide-voltage operation from 2.3 to 3.6 V.

5.5 Low-Power Operating Modes

This section describes the low-power modes supported by the module to optimize battery life.

5.5.1 Low-Power Deep Sleep

The low-power deep-sleep (LPDS) mode is an energy-efficient and transparent sleep mode that is entered automatically during periods of inactivity based on internal power optimization algorithms. The module draws about 7 µA from the supply in this low-power mode. The module can wake up in less than 3 ms from the internal timer or from any incoming host command. Typical battery drain in this mode is 140 µA. During LPDS mode, the module retains the software state and certain configuration information. The operation is transparent to the external host; thus, no additional handshake is required to enter or exit this sleep mode.

5.5.2 Hibernate

The hibernate mode is the lowest power mode in which all of the digital logic is power-gated. Only a small section of the logic powered directly by the main input supply is retained. The real-time clock (RTC) is kept running and the module wakes up once the n_HIB line is asserted by the host driver. The wake-up time is longer than LPDS mode at about 50 ms.

NOTE

Wake-up time can be extended to 75 ms if a patch is loaded from the serial flash.
