Overview
The M24128-BRMN6P, produced by STMicroelectronics, is a 128-Kbit I²C-compatible EEPROM (electrically erasable programmable memory) organized as 16 K × 8 bits. This device is part of the M24128 series, which offers a range of supply voltage options and advanced features for various applications.
The M24128-BR model, specifically, operates with a supply voltage from 1.8 V to 5.5 V and supports clock frequencies up to 1 MHz. It is designed to operate over an ambient temperature range of -40 °C to +85 °C, making it suitable for a wide range of environments.
The device includes an additional 64-byte identification page in the M24128-D variant, which can be used to store sensitive application parameters and later permanently locked in read-only mode.
