Description
24LC21A/SN Overview
The Mount surface mount is a popular choice for electronic components due to its compact size and ease of installation. With the mounting type being surface mount, the component can be easily attached to a surface without the need for additional hardware. This particular component has 1 function, making it ideal for simple applications. It has a nominal supply current of 3mA, ensuring efficient power consumption. The memory type is non-volatile, meaning it can retain data even when power is removed. With a clock frequency of 400kHz, data can be transferred quickly and efficiently. The memory interface is I2C, allowing for easy communication with other devices. The memory width of 8 and serial bus type of I2C further enhance its versatility. Measuring at a length of 4.9mm, this component is compact yet powerful.
