There is a memory type Non-Volatile for this type of device. It is supplied votage within Tray. As you can see, it is embedded in 8-SOIC (0.154, 3.90mm Width) case. This chip has an 64Kb 8K x 8 size of memory on it, so a lot of data can be stored on it. Memory data is stored in FRAM-format, which is common in mainstream devices. The device's extended operating temperature range of -40°C~85°C TA makes it ideal for many demanding applications. The device is capable of handling a supply voltage of 2.7V~3.6V volts. A Surface Mount mounting type is recommended for this product. With a clock frequency of 20MHz, the memory rotates on its own. The memory device is enclosed in a package with an 8-pin connector. This device must not operate below -40°C . As a general rule, memory ics is recommended that the product be operated at temperatures no higher than 85°Cc, otherwise, damage could be done to it. This memory ics should not be operated with a voltage below 2.7V volts at the minimum. Its operating voltage shall not exceed 3.6V. As a result of the frequency of this memory chip, data can be processed at a rate of 20MHz.
