Non-Volatile is its memory type. The case comes in Tape & Reel (TR) size. An embedded 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) case surrounds memory ics. Memory size on the chip is 64Kb 8K x 8. There is a mainstream memory format used by this device, which is called EEPROM-format memory. With an extended designed operating temperature of -40°C~125°C TA, this device is capable of lots of demanding applications. With 1.8V~5.5V as the supply voltage, it is capable of handling memory ics. The recommended mounting type for this device is Surface Mount. In order to operate effectively, the memory rotates at a clock frequency within a range of 10MHz. When choosing similar parts, 25AA640A is frequently referred to as the device's base part number. The memory device has an 8-pin package, which encloses it in a small package. The SPI type serial bus this memory integrates with is helpful to carry and transfer data to the CPU.
