Description

The 24LC08B-I/SN is a serial Electrically Erasable Programmable Read-Only Memory (EEPROM) from Microchip Technology, offering non-volatile storage with an 8-Kbit capacity organized as 1,024 x 8 bits. It employs an I²C bus protocol for communication, enabling efficient data transfer with a two-wire serial interface. Operating at a voltage range of 2.5V to 5.5V, it is suitable for a variety of applications including consumer electronics, communications, and industrial systems.
This EEPROM provides features such as byte-level write capability, compatibility with Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) I²C modes, and a page write buffer of 16 bytes to optimize write operations. It includes hardware write protection for data security and supports up to 1,000,000 write cycles with data retention of over 200 years. Packaged in an 8-pin SOIC, it is designed for easy integration into space-constrained environments. The 24LC08B-I/SN is reliable and ideal for applications requiring low-power, high-endurance EEPROM solutions.
