M93C46-WMN6P

Memory IC Overview

The M93C46-WMN6P is a 1-Kbit (128 x 8 or 64 x 16) electrically erasable programmable read-only memory (EEPROM) manufactured by STMicroelectronics. It utilizes the MICROWIRE serial interface with a maximum clock frequency of 2 MHz. The device operates within a supply voltage range of 2.5 V to 5.5 V and supports an ambient operating temperature from -40 °C to +85 °C. It features byte, word, and page write capabilities within 5 ms, over 4 million write cycles endurance, and more than 200 years of data retention.

Memory IC Feature Summary

• Supports dual memory organization for either 8-bit bytes or 16-bit words via the ORG pin configuration.
• Includes a READY/BUSY status signal to monitor programming completion without polling delays.
• Features an on-chip clock pulse counter to prevent instruction misalignment during noisy operations.
• Provides enhanced electrostatic discharge protection rated at 4000 V according to the human body model.

Memory IC Applications

• Configuration storage in industrial control systems
• Parameter memory for embedded microcontroller applications
• Data logging in automotive electronic modules

Memory IC Procurement Notes

Verify the specific suffix MN6P against the manufacturer's current datasheet to confirm package dimensions and environmental compliance details. Ensure the ordering code matches the required tape and reel or tube packaging format for your assembly line. Cross-reference the RoHS status with the latest regulatory documentation before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a 1-Kbit capacity with MICROWIRE compatibility is required. Choose the W-series variant specifically for applications requiring a minimum supply voltage of 2.5 V rather than the R-series which supports 1.8 V. Confirm that the system design accommodates the SOIC-8 surface mount package constraints and thermal requirements.

Memory IC Part Context

This part belongs to the M93Cx6 family of serial EEPROMs, which includes capacities ranging from 1 Kbit to 16 Kbit. The M93C46 represents the entry-level density in this series, sharing identical interface protocols and electrical characteristics with higher-capacity siblings like the M93C56 and M93C66.

Memory IC Replacement Considerations

Compatible substitutes include other M93C46 variants from STMicroelectronics such as M93C46-WMN6TP or M93C46-WMN6R, provided the package type and voltage specifications align with the original design requirements.
