In terms of its memory type, it can be classified as Non-Volatile. It is available in a case with a Tube shape. 32-CDIP (0.600, 15.24mm) case encloses it. 4Mb 512K x 8 is the chip's memory size. Memory data is stored in EEPROM-format, which is common in mainstream devices. Due to its wide operating temperature range, this device can be used in a wide variety of demanding applications. There is a voltage range of 4.5V~5.5V for the supply voltage. As far as the mounting type is concerned, Through Hole is recommended. There are 32 terminations on the chip. In total, this part supports 1 functions. In order to operate this memory device, it must be supplied with 5V of power. When selecting similar parts for the ic memory chip, AT28C040 is often referred to. While this memory chip features many merits, it also offers AUTOMATIC WRITE for improving system performance. In terms of power requirements, this memory chip uses only 5V . It is able to operate from a max supply current of 0.08mA. A programming voltage of 5V is needed to alter the state of certain nonvolatile memory arrays.
