24LC21T/SN Product Details

24LC21T/SN Overview


In this case, the memory type of the device can be classified as Non-Volatile. It is supplied votage within Tape & Reel (TR). 8-SOIC (0.154, 3.90mm Width) case encloses it. On the chip, there is an 1Kb 128 x 8 memory, which is the size of the chip's memory. There is a EEPROM-format memory used in this device, which is the memory format used by mainstream devices. Suitable for use in a wide range of demanding applications, this device offers an extended operating temperature range of 0°C~70°C TA. The supply voltage can be up to 2.5V~5.5V. The recommended mounting type for this device is Surface Mount. On the chip, there are 8 terminations. This part supports as many as 1 functions for the comprehensive working procedure. In order to operate this memory device, it must be supplied with 3V of power. With a clock frequency of 400kHz, the memory rotates on its own. As the base part number for the device, 24LC21 is frequently used to select similar items. An 8-pin package is used to package this memory device. The memory device has 8 pins, which means that it has 8 memory locations, which indicates it is an 8-bit device. This chip uses Surface Mount mounting, a straightforward, high-efficiency method of mounting. It is rated 3mA for its nominal supply current when it comes to the memory component. Although it has all the merits this chip has, it is also equipped with 2-WIRE SERIAL INTERFACE; DATA RETENTION > 200 YEARS; 1000000 ERASE/WRITE CYCLES GUARANTEED to give a performance boost to the system. As for the power supply, this memory chip only needs 3/5V . The I2C type serial bus this memory integrates with is helpful to carry and transfer data to the CPU.
