Microchip Technology's 24LC21A-PB27 is a serial EEPROM device featuring a memory organization of 128 words by 8 bits, providing a total density of 1024 bits. This CMOS component operates via an I2C serial bus interface, supporting synchronous operation with a maximum clock frequency of 400 kHz. The device utilizes open-drain output characteristics and is housed in a plastic PDIP8 package, a through-hole component with a standard 2.54 mm terminal pitch. Operating from a supply voltage range of 2.5V to 5.5V, with a nominal 3V, it functions within an ambient temperature range of 0°C to 70°C. The write cycle time is specified as a maximum of 10 ms. This component is suitable for applications in industrial control, consumer electronics, and automotive systems requiring non-volatile data storage.
