    Products Detail

    25LC640-E/SN Overview


    In terms of its memory type, it can be classified as Non-Volatile. The case comes in Tube size. The case is embedded in 8-SOIC (0.154, 3.90mm Width). Memory size on the chip is 64Kb 8K x 8. This device uses takes advantage of the EEPROM format. The device's extended operating temperature range of -40°C~125°C TA makes it ideal for many demanding applications. The device is capable of handling a supply voltage of 2.5V~5.5V. The recommended mounting type for this device is Surface Mount. On the chip, there are 8 terminations. The comprehensive working procedure is supported by 1 functions in this part. A voltage of 5V is required for the operation of this memory device. There is a clock frequency rotation of the memory within a 3MHz range. It is common to select similar parts by referring to the device's base part number, 25LC640. An 8-pin package is used to package this memory device. A memory device like this has 8 pins, indicating that there are 8 memory locations on the device. There is a note stating that this memory chip operates at 5V. As far as its nominal supply current is concerned, this memory component carries a rating of 5mA. It also features 1000K ERASE/WRITE CYCLES; DATA RETENTION > 200 YEARS to boost system performance despite all its merits. This memory chip requires only 5V of power.
