ST78C34CJ44-F Product Details

ST78C34CJ44-F Overview


Alternatively, UART can be purchased in the cost-effective PLCC package.The configuration uses 44 terminations.During operation, it receives a voltage of 5V.This device is an integrated circuit with 44 pins.In order for the equipment to work for a long period of time, it should not be allowed to reach a temperature above 0°C.UART is recommended that the operating temperature does not exceed 70°C to ensure long-term, normal performance.A configuration of the chip is determined by its 44 pins.A mounting method of Surface Mount is used.Providing power supplies of 5V makes it reliable and efficient for electronic designers.To ensure its high efficiency, a voltage of 5.5V is provided as the supply voltage.Universal asynchronous receiver-transmitter uses 4mA as the supply current, which is suUniversal asynchronous receiver-transmitterable for a specific application.Transferring data is not possible with 20 I/Os.
