128-BFQFP contains it. This packaging has a Tray-shape, making it convenient to carry around. Keeping the temperature at 0°C~70°C will ensure reliable operation. If you use a 1.8V 2.5V 3.3VV power supply, you should have no problem. KSZ8851 numbers are members of this family. Using 128 pins allows the device to operate. A 85mA-current supply is provided to the gadget. For maximum efficiency, the supply voltage should be set to 3.3V. There is currently a supply of 85mA in the market. 70°C°C is the maximum operating temperature that enables stable operation. It operates at a minimum working temperature of 0°C degrees Celsius to ensure reliability. As far as transceivers are concerned, there are 1 transceivers. The part owns 1 ports. It requires 85mA as the greatest current to function. Despite a supply voltage of 3.5VV, it can withstand it. It can work with a source voltage of 3.1V as low as possible.
