MT48V4M32LFB5-8:G Product Details
MT48V4M32LFB5-8:G Overview
As far as its memory type goes, it falls into the Volatile category. In addition, memory ics is available in a Tray case as well. 90-VFBGA case encloses it. There is an 128Mb 4M x 32 memory capacity on the chip. In this device, the memory is of the DRAM-format, which is a popular format in the mainstream computing sector. Due to its extended operating temperature range, the device is well suited for a wide range of demanding applications. The supply voltage can be up to 2.3V~2.7V. It is recommended that the mounting type be Surface Mount. As you can see from the diagram, the chip is planted with 90 terminations. This part supports as many as 1 functions for the comprehensive working procedure. The memory device designed for this application has been designed to be powered by an 2.5V power supply. In order to operate effectively, the memory rotates at a clock frequency within a range of 125MHz. It is common to select similar parts by referring to the device's base part number, MT48V4M32. The memory device is enclosed in a package with an 90-pin connector. I have noticed that the memory device has 90 pins, which indicates that it has 90 locations in the memory. According to the datasheet, this memory chip operates at an operating voltage of 2.5V. In this chip, the Surface Mount mounting method is used, a straightforward, high-efficiency mounting method. As far as the nominal supply current of this memory component is concerned, it is rated at 115mA. Despite all the merits of this chip, it also has AUTO/SELF REFRESH to boost system performance. Several ports on this chip are used to access one memory address for reading and writing. I/O port addresses on this device are mapped to memory addresses of COMMON bits.
