The CC3100 is a groundbreaking Wi-Fi CERTIFIED chip designed for wireless networking solutions. It’s part of Texas Instruments' innovative SimpleLink Wi-Fi family, making it easier than ever to integrate the Internet of Things into your projects. By bundling Wi-Fi and Internet protocols into a single chip, the CC3100 significantly reduces the burden on the host MCU's software. With robust security protocols built-in, this chip offers a seamless and secure connection experience. Additionally, the CC3100 comes with a comprehensive suite of tools, including software, sample applications, and detailed user guides, along with access to the TI E2E community for support. Its compact QFN package makes it easy to implement in your designs.
The Wi-Fi network processor subsystem boasts an on-chip Wi-Fi network and features a dedicated ARM MCU, which handles Wi-Fi and Internet tasks independently of the host MCU. This subsystem includes an 802.11b/g/n radio, baseband, and MAC, along with a powerful encryption engine capable of supporting fast and secure Internet connections using 256-bit encryption. The CC3100 supports multiple operation modes, including station, access point, and Wi-Fi Direct. It also complies with advanced security standards like WPA2 Personal, Enterprise Security, and WPS 2.0. Furthermore, the chip includes embedded TCP/IP and TLS/SSL stacks, an HTTP server, and multiple Internet protocols.
The power management subsystem features an integrated DC-DC converter that supports a wide range of supply voltages. It also includes low-power modes such as sleep mode, which consumes only 4μA of current.
The CC3100 can connect to any 8-bit, 16-bit, or 32-bit MCU through an SPI or UART interface. Its driver minimizes the memory footprint required by host systems, needing less than 7KB of code memory and 700B of RAM for typical TCP client applications.
