Overview
The M24256-BWMN6P is a 256-Kbit I2C-compatible 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-BWMN6P operates with a single supply voltage and supports high-speed I2C bus modes up to 1 MHz. It is available in various packages, including SO8, TSSOP8, UFDFPN8, and WLCSP, all of which are RoHS-compliant and halogen-free (ECOPACK2).
