Description

The 24LC256T-E/MS is a 256-Kilobit (32K x 8) serial EEPROM from Microchip Technology, utilizing I²C (Inter-Integrated Circuit) communication protocol. It is designed for non-volatile memory storage, meaning it retains data even when power is removed. Key features include a wide operating voltage range from 1.7V to 5.5V, low power consumption, and a maximum clock frequency of 400 kHz in standard mode, which can be extended up to 1 MHz in fast mode. The device supports byte-level and page-level writing, with a page size of 64 bytes, and features hardware write protection to prevent accidental data loss. The 24LC256T-E/MS is housed in an 8-lead MSOP (Mini Small Outline Package) for compact design requirements. It is highly reliable and suitable for applications in consumer electronics, industrial systems, and automotive environments where long-term data retention and multiple write cycles are necessary. The EEPROM's endurance rating is 1 million write/erase cycles, and it can retain data for up to 200 years, ensuring long-term stability and performance.
