24LC256T-E/ST

24LC256T-E/ST Description

The 24LC256T-E/ST from Microchip Technology is a high-performance 256Kbit (32K x 8) serial EEPROM designed for reliable non-volatile data storage in embedded systems. It operates over a wide voltage range (2.5V–5.5V), making it compatible with both 3.3V and 5V systems. The device features an I2C interface with a 400 kHz clock frequency, ensuring efficient data transfer, and offers a fast 900 ns access time for rapid read operations. With a 5ms write cycle time (word/page), it balances speed and endurance, supporting up to 1 million write cycles. Packaged in an 8-pin TSSOP and delivered in Tape & Reel (TR), it is optimized for automated assembly.
