The Microchip Technology 24LC21A-I-SNG is a 1024-bit serial CMOS EEPROM organized as 128 words by 8 bits. This component features a standard 2-wire serial interface compliant with the I2C protocol, supporting clock frequencies up to 400 kHz. It operates within a supply voltage range of 2.5V to 5.5V and is specified for industrial temperature ranges from -40°C to +85°C. The device is housed in a compact, rectangular plastic small outline package (PDSO8) with a terminal pitch of 1.27mm, making it suitable for surface-mount applications. Its compact memory density and efficient serial interface are beneficial in various industrial control, consumer electronics, and automotive systems. The maximum write cycle time (tWC) is 10ms.
