A mobile phone network consists of 32macro cells, which are radio coverage cells served by a high-power cell site (tower, antenna or mast).PLCC is the package in which it resides.There are 33 I/Os programmed in it.The device is programmed with 44 terminations.As the terminal position of this electrical part is QUAD, it serves as an important access point for passengers and freight.Power is provided by a supply voltage of 1.8V volts.The chip is programmed with 44 pins.For high efficiency, the supply voltage should be maintained at 1.8V.In order to store data, ROMless is used.The device is designed with pins 44.In this case, the maximum supply voltage (Vsup) reaches 1.9V.Ideally, the operating temperature should be greater than 0°C.It is recommended that the operating temperature be lower than 70°C.It is composed of 2 logic blocks (LABs).It is recommended that the maximal frequency be lower than 323MHz.Types of programmable logic are divided into FLASH PLD.
