There is a memory type Non-Volatile for this type of device. The case comes in Tray size. An embedded 32-TFSOP (0.724, 18.40mm Width) case surrounds memory ics. The chip has an 4Mb 512K x 8 memory. Memory data is stored in FLASH-format, which is common in mainstream devices. Due to its extended operating temperature range, the device is well suited for a wide range of demanding applications. With 2.7V~3.6V as the supply voltage, it is capable of handling memory ics. It is recommended to mount it in the Surface Mount mounting type. The chip has 32 terminations. In total, 1 functions are supported by this part. In order to operate this memory device, it must be supplied with 3.3V of power. It is common to select similar parts by referring to the device's base part number, M29W040. A 32-pin package containing this memory device is used to house this device. A memory device like this has 32 pins, indicating that there are 32 memory locations on the device. When it comes to power supplies, this memory chip only requires 3/3.3V . The device is able to run from a max supply current of 0.02mA , so it can be used in any environment. To alter the state of certain nonvolatile memory arrays, 2.7V programming voltage is required. As a result, this memory has 8 specific divisions of varying sizes.
