A package containing materials from Tube is provided. For the purpose of saving board space, it is provided in the 20-SOIC (0.295, 7.50mm Width). Known for its high quality and reliable performance, it is a type of Nonvolatile RAM. Set the operating temperature to 0°C~70°C. 4.75V~5.5V voltage should be supplied for its normal operation. Based on the technique of Surface Mount, it is mounted. To prevent signals from reflecting off the end of a transmission line, 20 terminations are used. Approximately 5V volts are supplied to the device. The 20 pins are configured on the board. A component's tolerance for high temperatures determines the reflow temperature limit 245. There is an integration of uPs/uCs/peripheral IC in the MICROPROCESSOR CIRCUIT.
