M93S56-WMN6P

Memory IC Overview

The M93S56-WMN6P is a 2 Kbit (128 x 16) Microwire serial EEPROM manufactured by STMicroelectronics. It operates within a supply voltage range of 2.5 V to 5.5 V and supports clock frequencies up to 2 MHz. The device features an 8-pin SOIC package, with an operating temperature range from -40 °C to +85 °C. Key specifications include more than 4 million write cycles, data retention exceeding 200 years, and user-defined write protection capabilities.

Memory IC Feature Summary

• Supports Microwire bus serial interface for efficient data access
• Provides user-definable write-protected memory areas
• Includes ready/busy signal during programming operations

Memory IC Applications

• Industrial control systems requiring non-volatile configuration storage
• Consumer electronics needing parameter retention
• Automotive modules compatible with standard serial interfaces

Memory IC Procurement Notes

Verify the specific suffix 'WMN6P' against the manufacturer's current datasheet to confirm package type and compliance status. Ensure the design accommodates the Microwire protocol requirements. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Memory IC Selection Notes

Select this component when a 16-bit wide serial EEPROM is required over 8-bit alternatives. It is suitable for applications needing block protection and high endurance. Compare with M93S46 or M93S66 variants if different memory densities are needed while maintaining the same interface and package constraints.

Memory IC Part Context

This part belongs to the M93Sx6 series of Microwire serial EEPROMs. It shares architectural similarities with other devices in the family, such as the M93S46 and M93S66, differing primarily in memory organization and capacity. The series is designed for low-power, space-constrained embedded applications.

Memory IC Replacement Considerations

Direct substitutes within the same series include M93S46-WMN6P (1 Kbit) and M93S66-WMN6P (4 Kbit). Verify pin compatibility and software driver adjustments for word size differences before substitution.
