Overview
The M93C66-MN6TP is an electrically erasable programmable memory (EEPROM) device produced by STMicroelectronics. This device is part of the M93C series, which includes various memory sizes such as 1 Kbit, 2 Kbit, 4 Kbit, 8 Kbit, and 16 Kbit. The M93C66 specifically offers a 4 Kbit memory capacity, accessible through the industry-standard MICROWIRE™ bus protocol. The memory array can be configured either in bytes (x8b) or in words (x16b), providing flexibility in data organization and access.
The device operates within a voltage supply range of 2.5 V to 5.5 V for the M93C66-W version and 1.8 V to 5.5 V for the M93C66-R version, ensuring compatibility with a wide range of applications. It supports a clock frequency of up to 2 MHz and operates over an ambient temperature range of -40 °C to +85 °C.
