A Volatile-type memory can be classified as the memory type of this device. Case Tube is available. The 44-BSOJ (0.400, 10.16mm Width) case contains it. There is 4Mb 256K x 16 of memory on the chip. SRAM-format memory is used in this device, which is a mainstream design. Due to its wide operating temperature range, this device can be used in a wide variety of demanding applications. A supply voltage of 4.5V~5.5V can be applied to it. Its recommended mounting type is Surface Mount. It is encased in an 44-pin package that contains this ic memory chip. There is a note indicating that this memory chip operates at an 5V volt supply voltage. Several ports on this chip are used to access one memory address for reading and writing. This device must not operate below 0°C . 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. It is recommended that the minimum supply voltage for this part be no less than 4.5V. An operating voltage of no more than 5.5V is required. In this ic memory chip, the frequency can be clocked at up to 83MHz times per second.
