M93S46-MN6T

Memory IC Overview

The M93S46-MN6T is a 1-kbit serial electrically erasable programmable read-only memory (EEPROM) manufactured by STMicroelectronics. It features a Microwire-compatible three-wire serial interface and supports a maximum clock frequency of 2 MHz. The device is organized as 64 words of 16 bits each. It operates within a supply voltage range of 2.5 V to 5.5 V and functions across an ambient temperature range of -40 °C to +85 °C. The component is housed in an 8-pin SOIC package.

Memory IC Feature Summary

• Supports Microwire bus serial access with user-defined write protection areas
• Provides enhanced electrostatic discharge (ESD) protection capabilities
• Ensures high reliability with over four million write cycles endurance

Memory IC Applications

• Industrial control systems requiring non-volatile data storage
• Consumer electronics for configuration parameter retention
• Automotive modules utilizing standard serial communication protocols

Memory IC Procurement Notes

Verify the exact suffix against official STMicroelectronics documentation, as variations such as MN6TP or MN6G may indicate specific tape-and-reel packaging or environmental compliance standards. Confirm that the requested part number matches the intended interface type and package dimensions required for your printed circuit board design before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a compact serial EEPROM with Microwire compatibility is required for low-power applications. Ensure the system design accommodates the 2.5 V to 5.5 V operating voltage range. Consider the 8-pin SOIC footprint during layout planning to ensure adequate clearance for surface-mount assembly processes.

Memory IC Part Context

This device belongs to the M93Sx6 family of serial EEPROMs from STMicroelectronics, which includes variants like the M93S46, M93S56, and M93S66. These parts share common interface characteristics but differ in memory density. The M93S46 specifically offers 1 Kbit capacity, making it suitable for applications needing moderate storage in a minimal footprint.

Memory IC Replacement Considerations

Compatible substitutes include the M93C46-WMN6TP for parallel interface alternatives or other M93S series variants if higher density is acceptable. Verify pinout compatibility and electrical specifications before substituting.
