Overview
The M24128-BWMN6P is a 128-Kbit I2C-compatible EEPROM (electrically erasable programmable memory) produced by STMicroelectronics. This device is organized as 16 K × 8 bits, providing a total of 128 Kbits or 16 Kbytes of memory. It operates within a wide supply voltage range, making it versatile for various applications. The M24128-BW model, specifically, operates with a supply voltage from 2.5 V to 5.5 V, while the M24128-BF and M24128-DF models can operate from 1.7 V to 5.5 V, and down to 1.6 V under certain conditions. The device supports I2C bus modes at 1 MHz, 400 kHz, and 100 kHz and is designed to function over an ambient temperature range of -40 °C to +85 °C.
