2 Reference Documents The documents listed below should be referenced for more information on the Freescale Tower system and the TWR‐WIFI‐RS2101. Refer to http://www.freesale.com/tower for the latest revision of all Tower documentation. • TWR‐WIFI‐RS2101 User Manual • TWR‐WIFI‐RS2101 Quick Start Guide • TWR‐WIFI‐RS2101 Lab Tutorial • RS9110‐N‐11‐21 Product Brief • RS9110‐N‐11‐21 Wi‐Fi Module Abridged Datasheet 3 Hardware Features This section provides more details about the features and functionality of the TWR‐WIFI‐RS2101. 3.1 RS9110N1121 Module The RS9110‐N‐11‐21 module from Redpine's Connect‐io‐n™ family of products is a complete IEEE 802.11bgn Wi‐Fi client device with a standard serial or SPI interface to a host processor or data source. It integrates a MAC, Baseband processor, RF transceiver with power amplifier, a frequency reference, an antenna, and all WLAN protocol and configuration functionality in embedded firmware to provide a self‐contained 802.11n WLAN solution for a variety of applications. No WLAN driver functionality is required on the host processor. Based on the Redpine Signals RS9110 SoC which includes an embedded processor, it is designed to provide standards compliant wireless connectivity to devices and systems that have a serial port and implement a TCP/IP stack. As a wireless serial modem, the RS9110‐N‐11‐21 handles SLIP packets and accepts AT commands for configuration, enabling a variety of M2M applications at low cost and small footprint. It uniquely provides connectivity in the single stream 802.11n mode, preserving overall network throughput in the emerging enterprise environments. For the TWR‐WIFI‐RS2101 Tower Peripheral Module, the RS9110‐N‐11‐21 module communicates with the MCU through an SPI. Figure 2 shows a functional block diagram of the RS9110‐N‐11‐21module. Refer to the RS9110‐N‐11‐... -
