25AA640/S Overview

Non-Volatile is its memory type. It is available in a case with a Tray shape. As you can see, it is embedded in Die case. There is an 64Kb 8K x 8 memory capacity on the chip. 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. A voltage of 1.8V~5.5V is possible to be applied to the supply. There is a recommendation that Surface Mount mounting type should be used for this product. As you can see from the diagram, the chip is planted with 8 terminations. In total, 1 functions are supported by this part. The memory device designed for this application has been designed to be powered by an 2.5V power supply. With a clock frequency of 1MHz, the memory rotates on its own. To select similar parts, many people use the device's base part number 25AA640. It has 8 pins indicating it has 8 memory locations. While this memory chip features many merits, it also offers DATA RETENTION > 200 YEARS; 4KV ESD PROTECTION; 1M ENDURANCE CYCLES for improving system performance. This memory chip requires a mere 2/5V of power. By integrating with the SPI-type serial bus, this memory transmits data to the processor. This memory ics is capable of operating with an input current of 0.005mA at max.
