TF-331 Web Server Controller

TF-331

The TF-331 Web Server Controller provides a very low cost, high performance SoC solution for consumer, networking and industrial device manufacturers that require remote monitoring, control and management through the LAN or Internet using a Web browser via broadband or dial-up network. TCP/IP protocol stack and networking utilities are embedded in the internal 64KB ROM which reduces software development efforts and improves performance. The TF-331 includes two UARTs, (one supports high speed, up to 1Mbps), a 10/100M Ethernet MAC and five GPIO ports to connect different devices. The performance of the TF-331 is further improved with the use of hardware Protocol Accelerators and flexible DMA engines. The hardware Protocol Accelerator in the TF-331 accelerates the handling of TCP, IP, UDP and ICMP protocols. Nine DMA channels are used for data transfer, no CPU intervention is required to serve these functions. The pipelined RISC CPU in the TF-331 is used for handling high-level protocol layer applications. Up to 4MB of SRAM and Flash memory can be addressed by the TF-331. The HTTP server software and most applications can be run using the embedded 24KB of SRAM without adding any external memory. The high speed UART interface can be used for connecting to devices such as Bluetooth or modem. The built-in 10/100Mbps Ethernet MAC on the TF-331 allows easy connection to the LAN. When connected to the LAN, the external flash write access capability can be used for online firmware update. With the bundled HTTP Server software and the low memory requirements, the TF-331 is the most cost effective solution for implementing an embedded web server design.
