There is a memory type Volatile for this type of device. It is available in a case with a Tube shape. An embedded 28-BSOJ (0.300, 7.62mm Width) case surrounds memory ics. It is estimated that the memory size on the chip is 256Kb 32K x 8. In this device, the memory is of the SRAM-format, which is a popular format in the mainstream computing sector. The device's extended operating temperature range of -40°C~85°C TA makes it ideal for many demanding applications. A voltage of 4.5V~5.5V is possible to be applied to the supply. As far as the mounting type is concerned, Surface Mount is recommended. A package of 28 pins is used to protect this memory device. According to the datasheet, this memory chip operates at an operating voltage of 5V. Several ports on this chip are used to access one memory address for reading and writing. This device must operate at a minimum temperature of -40°C. It should not be operated above 85°C°C. In order for this part to work properly, there must be a minimum voltage supply of 4.5V volts. The operating voltage of the memory ics shall not exceed 5.5V.
