M93S66-WBN6

Memory IC Overview

The M93S66-WBN6 is a 4-kbit serial Electrically Erasable Programmable Read-Only Memory (EEPROM) manufactured by STMicroelectronics. It features an SPI interface with a maximum clock frequency of 2 MHz and operates within a supply voltage range of 2.5 V to 5.5 V. The device is housed in an 8-pin DIP package and supports data retention for up to 200 years. It is designed for surface mount or through-hole installation, functioning reliably between -40°C and +85°C.

Memory IC Feature Summary

• Supports high-speed serial communication via SPI interface
• Provides non-volatile data storage with long-term retention capabilities
• Operates across a wide industrial temperature range

Memory IC Applications

• Industrial control systems requiring parameter storage
• Consumer electronics for configuration data retention
• Automotive modules needing reliable memory solutions

Memory IC Procurement Notes

Verify the specific suffix 'WBN6' against official STMicroelectronics documentation to confirm pinout compatibility and package type. Ensure the ordering information matches the required DIP configuration. Cross-reference the datasheet revision date to guarantee alignment with current manufacturing standards and environmental compliance requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when an SPI interface is preferred over Microwire for system integration. Consider the 8-pin DIP package for prototyping or legacy board designs. Verify that the 2 MHz clock speed meets the system's timing constraints. Confirm that the 4-kbit capacity aligns with the application's data storage needs without excessive overhead.

Memory IC Part Context

This part belongs to the M93S66 series of serial EEPROMs from STMicroelectronics. The series includes variants with different bit densities and interfaces. The M93S66 specifically denotes the 4-kbit capacity version. It is part of a broader family designed for low-power, high-reliability memory applications in embedded systems.

Memory IC Replacement Considerations

Check for direct substitutes like M93S66-WMN6P for SOIC packages if form factor changes are acceptable. Verify interface compatibility when considering alternative brands. Ensure voltage and temperature specifications match the original design requirements.
