SAB82C258A12N V2.1 – INFINEON

The Infineon SAB82C258A12N V2.1 is a high-performance single-chip Ethernet controller designed for embedded systems requiring robust TCP/IP communication. This specific variant features an integrated 10BASE-T transceiver and a direct memory access (DMA) controller, facilitating efficient data transfer between the network and the host processor. Its primary function is to handle all Ethernet protocol layers, reducing the processing burden on the host. Output voltage is rated at 3.3V, and output current at 500mA. It is packaged in a 144-pin PQFP (Plastic Quad Flat Pack) suitable for surface mount assembly. The operating temperature range is –40°C to 85°C, ensuring reliable operation in harsh environments. Common applications include industrial control systems, network-enabled sensors, and embedded web servers. Its integrated transceiver and DMA capabilities offer significant advantages by minimizing external component count and maximizing network throughput.
