A Volatile-type memory can be classified as the memory type of this device. Tape & Reel (TR)-cases are available. The file is embedded in a 48-TFBGA case. There is an 4Mb 256K x 16 memory capacity on the chip. This device uses a PSRAM-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 2.5V~3.6V can be supplied to memory ics. There is a recommended mounting type of Surface Mount for it. This memory device is enclosed in a 48-pin package. It is noted that the operating supply voltage of this memory is 3.3V. As a result of the Surface Mount mounting configuration, this chip is designed to be straightforward, high-efficiency, and easy to install. Several ports on this chip are used to access one memory address for reading and writing.
