A transmission line may also have 14 terminations, which are made using devices matched to its characteristic impedance. In the electronic industry, the 48-LQFP has a reputation for being economical. Materials are taken from Tape & Reel (TR)'s packaging. The mounting on the PCB is done with Surface Mount. It should not exceed 0°C~70°C°C when operating. The material qualifies for standard applications as a SCSI, LVD, SE-qualified material. Ensure normal operation with the 2.7V~5.25V Supply Voltage. There are also 48 pins available for specific purposes. As an example, 14 signal lines are lines dedicated solely to the transmission of signals or intelligence, which are either public or private. High efficiency requires a constant voltage supply of 3.3V.
