In terms of its memory type, it can be classified as Volatile. It is supplied votage within Tray. In the case of 90-TFBGA, it is embedded within the case. There is 256Mb 8M x 32 of memory on the chip. This device uses takes advantage of the DRAM format. The device's extended operating temperature range of -40°C~85°C TA makes it ideal for many demanding applications. The device is capable of handling a supply voltage of 3V~3.6V. The recommended mounting type for this device is Surface Mount. On the chip, there are 90 terminations. This part supports as many as 1 functions for the comprehensive working procedure. In order to operate this memory device, it must be supplied with 3.3V of power. With a clock frequency of 166MHz, the memory rotates on its own. This memory device is enclosed in a 90-pin package. The memory device has 90 pins, which means that it has 90 memory locations, which indicates it is an 90-bit device. Although it has all the merits this chip has, it is also equipped with AUTO/SELF REFRESH to give a performance boost to the system. Using 1 ports, a single memory address can be read and/or written. The power supply needed for this memory chip is only 3.3V . An COMMON-bit memory mapped I/O port address is used to address this device. A maximum supply current of 0.35mA can be used to operate this device.
