W3100A-LF TCP/IP (RoHS) TCP/IP IC

Not recommended for new designs.

Performance Benefit

• Line-speed data transmission by hardwired logic and Saving MCU processing power by TCP/IP offload

Implementation Benefit

• Easy control way like memory

Cost Benefit

• No OS required

Application Benefit

• As a Internet Controller : Easy embedded to controllers or data collectors with low-end MCUs
• As a Internet Accelerator :   Reducing Jitter with fixed processing time by
  hardware. Enhancing video and voice quality.
