As far as memory types are concerned, Non-Volatile is considered to be its memory type. There is a Tray case available. 48-TFSOP (0.724, 18.40mm Width) case encloses it. A memory chip with a capacity of 4Mb 512K x 8 256K x 16 is used on this device. This device uses takes advantage of the FLASH format. The device's extended operating temperature range of 0°C~70°C TA makes it ideal for many demanding applications. It is capable of handling a voltage supply of 4.5V~5.5V. It is recommended to mount it in the Surface Mount mounting type. It is common to select similar parts by referring to the device's base part number, M29F400. The ic memory chip comes in a package with 48 pins that allows it to be connected to a computer. The operating supply voltage of this memory chip is noted to be 5V. This chip uses Surface Mount mounting, a straightforward, high-efficiency method of mounting. It is rated for a nominal supply current of 20mA for this memory component. There must not be a minimum operating temperature of less than 0°C for this device. Temperatures no higher than 70°C degrees Celsius are recommended for operation. If this part is to be used, the minimum supply voltage should not be less than 4.5V volts. The operating voltage of the memory ics shall not exceed 5.5V.
