In this case, the memory type of the device can be classified as Volatile. In addition, memory ics is available in a Tube case as well. The 44-BSOJ (0.400, 10.16mm Width) case contains it. A memory chip with a capacity of 4Mb 256K x 16 is used on this device. This device uses a SRAM-format memory, which is of mainstream design. A wide operating temperature range makes this device ideal for a variety of demanding applications. A voltage of 4.5V~5.5V is possible to be applied to the supply. Its recommended mounting type is Surface Mount. A package of 44 pins is used to protect this memory device. There is a note indicating that this memory chip operates at an 5V volt supply voltage. 1 ports allow read/write access to one memory address in this chip. There must be at least an 0°C operating temperature for this device. As a general rule, memory ics is recommended that the product be operated at temperatures no higher than 70°Cc, otherwise, damage could be done to it. This memory ics requires a minimum voltage of 4.5V. This part requires a minimum voltage of 5.5V.
