In terms of its memory type, it can be classified as Volatile. It is supplied votage within Tray. In the case of 44-TSOP (0.400, 10.16mm Width), it is embedded within the case. 4Mb 512K x 8 is the chip's memory size. 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~85°C TA. The device is capable of handling a supply voltage of 4.5V~5.5V volts. It is recommended to mount it in the Surface Mount mounting type. A voltage of 5V is noted as the operating supply voltage for this memory. A memory address is accessed through 1 ports on this chip. A minimum operating temperature of -40°C must be met by this device. Temperatures over 85°C°C are not recommended. In order for this part to work properly, there must be a minimum voltage supply of 4.5V volts. There shall be a voltage limit of 5.5V for its operation.
