24LCS21AT/SN Product Details

24LCS21AT/SN Overview


As far as its memory type goes, it falls into the Non-Volatile category. The case comes in Tape & Reel (TR) size. Embedded in the 8-SOIC (0.154, 3.90mm Width) case, memory ics is a single file. There is an 1Kb 128 x 8 memory capacity on the chip. There is a EEPROM-format memory used in this device, which is the memory format used by mainstream devices. With an extended designed operating temperature of 0°C~70°C TA, this device is capable of lots of demanding applications. The supply voltage can be up to 2.5V~5.5V. As far as the mounting type is concerned, Surface Mount is recommended. It is planted on the chip with 8 terminations. It supports up to 1 functions for comprehensive operation. The memory device designed for this application has been designed to be powered by an 3V power supply. With a clock frequency of 400kHz, the memory rotates on its own. Similar parts are frequently selected using the ic memory chip's base part number, 24LCS21A. In this ic memory chip, there is an 8-pin package that encloses the device. I have noticed that the memory device has 8 pins, which indicates that it has 8 locations in the memory. Chips such as this one are mounted using Surface Mount mounting, a straightforward method of mounting that is effective. It is rated for a nominal supply current of 3mA for this memory component. While this memory chip features many merits, it also offers DATA RETENTION > 200 YEARS; 1000000 ERASE/WRITE CYCLES GUARANTEED for improving system performance. When it comes to power supplies, this memory chip only requires 3/5V . By integrating this memory with a I2C-type serial bus, data can be carried and transferred to the CPU easily.
