As far as memory types are concerned, Volatile is considered to be its memory type. There is a Tape & Reel (TR) case available. The 44-TSOP (0.400, 10.16mm Width) case contains it. It is estimated that the memory size on the chip is 4Mb 256K x 16. There is a mainstream memory format used by this device, which is called SRAM-format memory. Suitable for use in a wide range of demanding applications, this device offers an extended operating temperature range of -40°C~125°C TA. A supply voltage of 2.5V~3.6V can be applied to it. It is recommended that the mounting type be Surface Mount. It is encased in an 44-pin package that contains this ic memory chip. A minimum operating temperature of -40°C is required for this device. As a general rule, memory ics is recommended that the product be operated at temperatures no higher than 125°Cc, otherwise, damage could be done to it. The minimum supply voltage for this part should not be less than 2.5V. A maximum voltage of 3.6V shall be allowed for its operating voltage.
