25LC640XT-I/ST Product Details

25LC640XT-I/ST Overview


There is a memory type Non-Volatile for this type of device. The case comes in Tape & Reel (TR) size. It is available in 8-TSSOP (0.173, 4.40mm Width) case. This chip has an 64Kb 8K x 8 size of memory on it, so a lot of data can be stored on it. There is a EEPROM-format memory used in this device, which is the memory format used by mainstream devices. Due to its extended operating temperature range, the device is well suited for a wide range of 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 that are planted. The comprehensive working procedure is supported by 1 functions in this part. In order to operate this memory device, it must be supplied with 5V of power. A clock frequency rotation within 2MHz is used for the ic memory chip to rotate data. To select similar parts, many people use the device's base part number 25LC640. The ic memory chip comes in a package with 8 pins that allows it to be connected to a computer. I have noticed that the memory device has 8 pins, which indicates that it has 8 locations in the memory. Memory chip's nominal supply current is 5mA. This chip is not only loaded with advantages, but it also comes with 1000K ERASE/WRITE CYCLES; DATA RETENTION > 200 YEARS, which boosts the performance of your system. As for power supplies, this memory chip requires just 3/5V . By integrating with the SPI-type serial bus, this memory transmits data to the processor.
