Its memory type can be classified as Non-Volatile. It is supplied votage within Tube. In the case of 40-DIP Module (0.610, 15.495mm), it is embedded within the case. On the chip, there is an 2Mb 128K x 16 memory, which is the size of the chip's memory. There is a mainstream memory format used by this device, which is called NVSRAM-format memory. 0°C~70°C TA is an extended operating temperature range, making this device ideal for demanding applications. A voltage of 3V~3.6V can be supplied to memory ics. A Through Hole mounting type is recommended for this product. The chip has 40 terminations. As many as 1 functions are supported for comprehensive working. Memory devices such as this one are designed to be powered by 3.3V and should be used as such. When choosing similar parts, DS1258W is frequently referred to as the device's base part number. The memory device in question has 40 pins, thus indicating that it has 40 memory locations that can be accessed. This memory chip requires a mere 3.3V of power. The device is able to run from a max supply current of 0.1mA , so it can be used in any environment. It is usually considered a type of SRAMs component. The frequency of data processing on this memory chip is 150GHz.
