Its memory type can be classified as Non-Volatile. In addition, memory ics is available in a Tape & Reel (TR) case as well. There is a 8-SOIC (0.154, 3.90mm Width) case embedded in it. There is an 1Kb 128 x 8 memory capacity on the chip. As with most mainstream devices, this one uses EEPROM-format memory. This device has an extended operating temperature range of -40°C~85°C TA, so it's perfect for a wide range of demanding applications. The device is capable of handling a supply voltage of 2.5V~5.5V volts. A Surface Mount mounting type is recommended for this product. On the chip, there are 8 terminations that are planted. The comprehensive working procedure of this part involves 1 functions. There is a requirement for 4V to be supplied to this ic memory chip in order to operate. In order to operate effectively, the memory rotates at a clock frequency within a range of 400kHz. A device's base part number, BR24C21, is often used in order to identify similar components. In this ic memory chip, there is an 8-pin package that encloses the device. It has 8 pins indicating it has 8 memory locations. As for the power supply, this memory chip only needs 3/5V . Integrated into this memory is a I2C-type serial bus that facilitates data transmission to the CPU. It is able to operate from a max supply current of 0.003mA.
