概要

Description

The AT24C32D-XHM-T is a 32-kbit (4K x 8) EEPROM (Electrically Erasable Programmable Read-Only Memory) produced by Microchip Technology. It operates on a supply voltage ranging from 1.8V to 5.5V and communicates via the I2C (Inter-Integrated Circuit) protocol, allowing multiple devices to be connected on the same bus. The device features a 16-byte page write capability, enabling efficient data storage and retrieval.
Key features include a write cycle time of typically 5 ms, 1 million write/erase cycles endurance, and data retention of up to 100 years. The AT24C32D-XHM-T is commonly used in applications such as configuration data storage, calibration constants, and in embedded systems for non-volatile data storage. Its compact SOIC-8 package makes it suitable for space-constrained designs. Overall, the AT24C32D-XHM-T is a versatile and reliable choice for various electronic applications requiring persistent memory.

Package
