Overview
The M93C66-MN6 is an electrically erasable programmable memory (EEPROM) device produced by STMicroelectronics. This component is part of the M93C series, which includes devices with 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, configurable either in bytes (x8) or words (x16).
The device operates using the industry-standard MICROWIRE™ bus protocol and is available in different voltage ranges, with the M93C66-W devices operating from 2.5 V to 5.5 V and the M93C66-R devices operating from 1.8 V to 5.5 V. It supports a clock frequency of up to 2 MHz and functions over an ambient temperature range of -40 °C to +85 °C.
