24LC21/SN Product Details

24LC21/SN Overview


Non-Volatile is its memory type. In addition, memory ics is available in a Tube case as well. 8-SOIC (0.154, 3.90mm Width) case encloses it. The chip has an 1Kb 128 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. It is supplied votage within 2.5V~5.5V. The recommended mounting type for memory ics 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 power this memory device, 3V will be necessary. It has a clock frequency of 400kHz. Similar parts are frequently selected using 24LC21, the device's base part number. There are 8 pins on the package of the memory device. It has 8 pins indicating it has 8 memory locations. It is rated 3mA for its nominal supply current when it comes to the memory component. While this memory chip features many merits, it also offers 2-WIRE SERIAL INTERFACE; 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.
