25LC640T-I/SN Overview

In this case, the memory type of the device can be classified as Non-Volatile. Tape & Reel (TR)-cases are available. The case is embedded in 8-SOIC (0.154, 3.90mm Width). Memory size on the chip is 64Kb 8K x 8. In this device, the memory is of the EEPROM-format, which is a popular format in the mainstream computing sector. With an extended designed operating temperature of -40°C~85°C TA, this device is capable of lots of demanding applications. A supply voltage of 2.5V~5.5V can be applied to it. Its recommended mounting type is Surface Mount. The chip has 8 terminations. For a comprehensive working procedure, this part supports as many as 1 functions. A voltage of 5V is required for the operation of this memory device. With a clock frequency of 2MHz, the memory rotates on its own. When selecting similar parts for the ic memory chip, 25LC640 is often referred to. A 8-pin package containing this memory device is used to house this device. I have noticed that the memory device has 8 pins, which indicates that it has 8 locations in the memory. The operating supply voltage of this memory chip is noted to be 5.5V. Memory chip's nominal supply current is 5mA. Although it has all the merits this chip has, it is also equipped with 1000K ERASE/WRITE CYCLES; DATA RETENTION > 200 YEARS to give a performance boost to the system. Power supplies for this memory chip are merely 3/5V . Its SPI-type serial bus helps transfer data to the CPU efficiently. Regarding voltage, the chip is well suited to a voltage range of 7V volts to 12 volts.
