M95P32-EXMNT/E

Memory IC Overview

The M95P32-EXMNT/E is a 32-Mbit serial SPI page EEPROM manufactured by STMicroelectronics. It features an extended temperature range of -40 °C to +105 °C and operates within a supply voltage of 1.6 V to 3.6 V. The device supports clock frequencies up to 80 MHz with dual and quad output capabilities. Memory organization includes 8192 programmable pages of 512 bytes, organized into 64-Kbyte blocks and 4-Kbyte sectors. It incorporates two additional 512-byte identification pages for UID storage and sensitive parameter locking.

Memory IC Feature Summary

• Supports high-speed SPI communication with dual and quad output modes for increased data throughput.
• Includes advanced error correction code (ECC) logic for double-bit correction and triple-bit error detection.
• Features hardware and software write protection mechanisms with block-level granularity.
• Provides ultralow power consumption with deep power-down mode and standby current specifications.

Memory IC Applications

• Industrial control systems requiring extended temperature operation
• Automotive electronics applications compliant with ISO26262 safety standards
• Embedded systems needing non-volatile configuration storage
• IoT devices utilizing low-power standby modes

Memory IC Procurement Notes

Verify the specific package variant corresponding to the suffix EXMNT/E against the official datasheet pinout diagrams. Confirm that the extended temperature grade (-40 °C to +105 °C) matches the system environmental requirements. Ensure compatibility with the required SPI clock frequency and voltage levels before integration.

Memory IC Selection Notes

Select this component when extended industrial or automotive temperature ranges are mandatory. The M95P32-E variant is distinct from the M95P32-I due to its wider thermal operating window. Consider the UFDFPN8 package dimensions if space constraints require a compact surface-mount solution.

Memory IC Part Context

This part belongs to the M95P32 family of ultra-low-power 32-Mbit serial SPI page EEPROMs. It shares core architecture with the M95P32-I but differs in temperature rating. The family utilizes ST's proprietary NVM technology to provide byte-write flexibility and high page cycling endurance equivalent to traditional EEPROMs.
