In this case, the memory type of the device can be classified as Volatile. It is available in a case with a Tray shape. 66-TSSOP (0.400, 10.16mm Width) case encloses it. 128Mb 32M x 4 is the chip's memory size. This device uses takes advantage of the DRAM format. Suitable for use in a wide range of demanding applications, this device offers an extended operating temperature range of 0°C~70°C TA. It is capable of handling a voltage supply of 2.3V~2.7V. There is a recommendation that Surface Mount mounting type should be used for this product. As you can see from the diagram, the chip is planted with 66 terminations. In total, this part supports 1 functions. Memory devices such as this one are designed to be powered by 2.5V and should be used as such. With a clock frequency of 167MHz, the memory rotates on its own. In order to select similar parts, typical manufacturers refer to MT46V32M4 as the device's base part number. The memory device in question has 66 pins, thus indicating that it has 66 memory locations that can be accessed. In spite of all the merits this chip has, it also features AUTO/SELF REFRESH to level up system performance. Each memory address is accessed by one of 1 ports on this chip. As for power supplies, this memory chip requires just 2.5V . There are I/O ports on this memory ics that have COMMON-bit memory mapping. It is able to operate from a max supply current of 0.355mA.
