DS1321E Overview
The item is packaged with the materials of Tube. A 20-TSSOP (0.173, 4.40mm Width) has been provided to save space on the board. As a type of Nonvolatile RAM, it provides high quality and reliable performance. -40°C~85°C should be set as the operating temperature. The voltage 4.75V~5.5V must be provided for the device to function normally. It is mounted based on the technique of Surface Mount. In addition to this part number, there are other electronic components that can be found based on its base part number DS1321. In order to prevent signals from reflecting back from the transmission line's end, 20 terminations are used. A voltage of 5V is used as the supply voltage for the device. The pin configuration is 20. As a result, the reflow temperature limit of 240 is determined by the component with the lowest tolerance for high temperatures. Electronic aparts with 20 channels are used. This item falls under the Power Management Circuits subcategory. In order to ensure the transmission of data, there are 1 channels. High efficiency can be achieved by using the power supplies of 5V. IC type POWER SUPPLY SUPPORT CIRCUIT is indicated in this case. It is a type of memory that stores information in the form of SRAM. There is a maximum current that may be supplied without degrading the characteristics or damaging the internal circuit as low as 1.5mA. A current is drawn by the device from its supply to supply 50μA. 5V depends on the voltage drawn from the device's supply.
