25LC040AT-E/ST Product Details

25LC040AT-E/ST Overview


Non-Volatile is its memory type. Tape & Reel (TR)-cases are available. An embedded 8-TSSOP (0.173, 4.40mm Width) case surrounds memory ics. The chip has an 4Kb 512 x 8 memory. The device uses a mainstream EEPROM-format memory. Due to its wide operating temperature range, this device can be used in a wide variety of demanding applications. The device is capable of handling a supply voltage of 2.5V~5.5V. It is recommended that the mounting type be Surface Mount. 8 terminations are planted on the chip. In total, this part supports 1 functions. In order to function properly, this ic memory chip should be powered by a voltage of 2.7V. During the rotation of the clock, the ic memory chip is set as 10MHz. A device's base part number, 25LC040A, is often used in order to identify similar components. It is encased in an 8-pin package that contains this ic memory chip. There are 8 pins on this memory device, which indicates it has 8 memory locations in it. It is noted that the operating supply voltage of this memory is 5V. This chip is configured to use Surface Mount mounting, a straight forward, high-efficiency mounting fashion. As far as its nominal supply current is concerned, this memory component carries a rating of 5mA. Although it has all the merits this chip has, it is also equipped with DATA RETENTION > 200 YEARS; 1,000,000 ERASE/WRITE CYCLES to give a performance boost to the system. By integrating this memory with a SPI-type serial bus, data can be carried and transferred to the CPU easily.
