M93C86-RMN3TP/K

Memory IC Overview

The M93C86-RMN3TP/K is a 16 Kbit automotive-grade serial EEPROM manufactured by STMicroelectronics. It utilizes the MICROWIRE interface with a maximum clock frequency of 2 MHz and supports dual memory organization of 2 k x 8 or 1 k x 16 bits. The device operates within a supply voltage range of 1.8 V to 5.5 V and is housed in an SOIC-8 surface-mount package. It meets AEC-Q100 qualification standards, ensuring reliability for automotive applications across a temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards
• Dual memory organization supporting both byte (x8) and word (x16) configurations
• Extended industrial temperature operation up to +125°C

Memory IC Applications

• Automotive electronic control units requiring non-volatile data storage
• Vehicle configuration parameter retention systems
• Industrial embedded systems needing robust serial memory

Memory IC Procurement Notes

Verify the specific suffix RMN3TP/K against official datasheets to confirm the 1.8V minimum operating voltage and automotive grade status. Ensure the SOIC-8 package dimensions match your PCB footprint requirements. Confirm that the MICROWIRE interface compatibility aligns with your microcontroller's serial peripheral capabilities before finalizing procurement.

Memory IC Selection Notes

Select this component when designing for automotive environments requiring high temperature tolerance and extended data retention. The 1.8V lower voltage limit makes it suitable for low-power systems compared to the 2.5V variant. Consider the 16Kbit capacity for storing larger calibration tables or vehicle identification data compared to smaller capacity devices in the same series.

Memory IC Part Context

This part belongs to the M93Cx6 family of serial EEPROMs from STMicroelectronics. It shares the MICROWIRE interface architecture with other members like the M93C46 and M93C56 but offers higher density. The 'R' suffix specifically denotes the wider voltage range starting at 1.8V, distinguishing it from the 'W' variant which starts at 2.5V.

Memory IC Replacement Considerations

M93C86-WMN3TP/S serves as a functional alternative if the system voltage does not drop below 2.5V. Verify that the pinout remains identical between the W and R variants to ensure direct socket compatibility without circuit modification.
