Non-Volatile is its memory type. It is available in a case with a Tray shape. As you can see, it is embedded in 48-TFSOP (0.724, 18.40mm Width) case. There is an 64Mb 8M x 8 4M x 16 memory capacity on the chip. In this device, the memory is of the FLASH-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. A voltage of 2.7V~3.6V is possible to be applied to the supply. 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 48 terminations. In total, 1 functions are supported by this part. The memory device designed for this application has been designed to be powered by an 3V power supply. To select similar parts, many people use the device's base part number M29W640. It is encased in an 48-pin package that contains this ic memory chip. It has 48 pins indicating it has 48 memory locations. While this memory chip features many merits, it also offers BOTTOM BOOT BLOCK for improving system performance. This memory chip requires a mere 3/3.3V of power. This memory ics is capable of operating with an input current of 0.02mA at max. A programming voltage of 3V is needed to alter the state of certain nonvolatile memory arrays. The manufacturer has divided this memory into 8127 different sections that have specific sizes in total.
