AT24C01D-SSHM-T: A Compact 1Kb I2C Serial EEPROM Solution by Microchip

The AT24C01D-SSHM-T is a 1-kilobit serial EEPROM memory chip manufactured by Microchip Technology, designed for low-power and space-constrained applications. This device is organized as 128 x 8 bits and operates via the I2C (Inter-Integrated Circuit) protocol, making it an ideal choice for embedded systems requiring reliable non-volatile memory.

One of the key features of the AT24C01D-SSHM-T is its low power consumption, which is critical for battery-powered devices such as IoT sensors, wearables, and portable electronics. With a write current of 3 mA and a standby current of just 6 μA, it ensures minimal energy usage during operation. The chip supports a wide voltage range from 1.7V to 5.5V, providing flexibility across various system designs.

The EEPROM offers high reliability with endurance of up to 1 million write cycles and data retention of 100 years. It includes hardware write-protection features, allowing users to safeguard critical data by controlling the WP (Write Protect) pin. The I2C interface enables easy integration with microcontrollers and other digital components, supporting clock frequencies up to 400 kHz for efficient data transfer.

Packaged in a space-saving 5-lead SOT-23, the AT24C01D-SSHM-T is suited for applications where PCB real estate is limited. Common uses include storing calibration data, device configuration parameters, and user settings in industrial, automotive, and consumer electronics.

ICGOOODFIND: The AT24C01D-SSHM-T stands out for its compact form factor, low power profile, and robust performance, making it a dependable choice for modern embedded memory needs.
