Overview
The M93C46-MN6 is an electrically erasable programmable memory (EEPROM) device produced by STMicroelectronics. This component is part of the M93C series, which includes various memory sizes, but the M93C46 specifically offers 1 Kbit of memory. The memory array can be configured either in bytes (x8b) or in words (x16b), providing flexibility in data organization. The device operates using the industry-standard MICROWIRE™ bus protocol and is designed to work within a voltage supply range of 2.5 V to 5.5 V for the M93Cx6-W version and 1.8 V to 5.5 V for the M93Cx6-R version. It is suitable for a wide range of electronic projects due to its robust features and reliability.
