25LC640-I/SN Overview

There is a memory type Non-Volatile for this type of device. It is available in a case with a Tube shape. It is available in 8-SOIC (0.154, 3.90mm Width) 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. The device's extended operating temperature range of -40°C~85°C TA makes it ideal for many demanding applications. A voltage of 2.5V~5.5V can be supplied to memory ics. There is a recommendation that Surface Mount mounting type should be used for this product. 8 terminations are planted on the chip. As many as 1 functions are supported for comprehensive working. In order to power this memory device, 5V will be necessary. During the rotation of the clock, the ic memory chip is set as 2MHz. It is common to select similar parts by referring to 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. The memory device has a total of 8 pins, thus indicating that it has a total of 8 memory locations. This memory runs on an 2.5V operating supply voltage. In terms of its nominal supply current, this memory component has a rating of 5mA. In spite of all the merits this chip has, it also features 1000K ERASE/WRITE CYCLES; DATA RETENTION > 200 YEARS to level up system performance. Talking about power supplies, this memory chip requires 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.
