There is a Volatile memory type associated with this device. The case comes in Tube size. An embedded 36-BSOJ (0.400, 10.16mm Width) case surrounds memory ics. 4Mb 512K x 8 is the chip's memory size. This device uses a SRAM-format memory, which is of mainstream design. 0°C~70°C TA is an extended operating temperature range, making this device ideal for demanding applications. A voltage of 4.5V~5.5V can be supplied to memory ics. There is a recommendation that Surface Mount mounting type should be used for this product. It is encased in an 36-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. A minimum operating temperature of 0°C must be met by this device. It is recommended for operation at temperatures no higher than. If this part is to be used, the minimum supply voltage should not be less than 4.5V volts. This part requires a minimum voltage of 5.5V.
