25AA640A-E/P Product Details

25AA640A-E/P Overview


As far as its memory type goes, it falls into the Non-Volatile category. In addition, memory ics is available in a Tube case as well. As you can see, it is embedded in 8-DIP (0.300, 7.62mm) case. The chip has an 64Kb 8K x 8 memory. In this device, the memory is of the EEPROM-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. With 1.8V~5.5V as the supply voltage, it is capable of handling memory ics. There is a recommendation that Through Hole mounting type should be used for this product. There is a clock frequency rotation of the memory within a 10MHz range. When selecting similar parts for the ic memory chip, 25AA640A is often referred to. The memory device has an 8-pin package, which encloses it in a small package. By integrating this memory with a SPI-type serial bus, data can be carried and transferred to the CPU easily.
