Overview
The M93C46-WMN6P is a 1 Kbit electrically erasable programmable memory (EEPROM) device manufactured by STMicroelectronics. This device is part of the M93Cx6 series, which includes various memory sizes such as 1 Kbit, 2 Kbit, 4 Kbit, 8 Kbit, and 16 Kbit. The M93C46-WMN6P is accessed through the industry-standard MICROWIRE™ bus protocol and can be configured either in bytes (x8) or words (x16).
The device operates within a voltage supply range of 2.5 V to 5.5 V and supports a clock frequency of up to 2 MHz. It features a self-timed programming cycle with auto-erase, a READY/BUSY signal during programming, and enhanced ESD/latch-up behavior. The M93C46-WMN6P is known for its high reliability, with more than 4 million write cycles and over 200 years of data retention.
