Renesas Electronics Corporation Controllers 1894KI-32LFT

The 1894KI-32LFT is a low-power integrated PHY device designed for 10BASE-T and 100BASE-TX Ethernet applications, compliant with ISO/IEC 8802.3 standards. It features an RMII interface and supports full-duplex operation at data rates of 10 Mb/s and 100 Mb/s. The device incorporates Auto-MDIX functionality, which automatically corrects crossover errors in wiring, enhancing installation flexibility. This PHY device utilizes digital signal processing for improved performance over unshielded twisted-pair category 5 cables, capable of handling attenuation exceeding 24 dB at 100 MHz. It includes a Serial Management Interface for configuration and status monitoring, along with programmable LED outputs to indicate various operational states such as link status and activity. The 1894KI-32LFT operates on a single 3.3V power supply and features low power consumption, with typical operating power around 300 mW and a power-down mode consuming approximately 21 mW. It is available in a compact 32-pin QFN package and is suitable for a variety of applications, including NIC cards, routers, and industrial equipment. The device is also offered in an industrial temperature range, making it suitable for more demanding environments.
