Overview
The M24256-DFMN6TP is a 256-Kbit serial I2C bus EEPROM (Electrically Erasable Programmable Read-Only Memory) produced by STMicroelectronics. This device is organized as 32 K x 8 bits, making it suitable for a wide range of applications requiring non-volatile memory. The M24256-DFMN6TP operates with a supply voltage from 1.7 V to 5.5 V and supports clock frequencies up to 1 MHz. It is designed to provide high-speed data storage and retrieval, with features such as byte and page write capabilities within 5 ms. The device also includes an identification page for storing sensitive application parameters, which can be permanently locked in read-only mode.
