Microchip Technology's 24LC21-P is a serial CMOS EEPROM with a density of 1 Kbit, organized as 128 words by 8 bits. This component operates with an I2C serial interface, supporting a maximum clock frequency of 400 kHz. It features a data retention period of 200 years and an endurance rating of 1,000,000 write cycles. The device is housed in a PDIP8 package and operates within a temperature range of 0°C to 70°C, with supply voltage requirements between 4.5V and 5.5V. The 24LC21 series is commonly integrated into applications within the industrial and consumer electronics sectors, where reliable non-volatile data storage is essential. The I2C control byte is defined as 1010XXXR, and the output characteristics are open-drain.
