MX25R8035FZUIH0

Memory IC Overview

The MX25R8035FZUIH0 is an 8-Mbit Serial NOR Flash memory from Macronix, utilizing the MXSMIO technology. It supports SPI Mode 0 and Mode 3 with Single, Dual, and Quad I/O configurations. The device operates on a single power supply ranging from 1.65V to 3.6V for all read, erase, and program operations. It features ultra-low power consumption modes alongside high-performance fast read capabilities. The memory array is organized into equal 4K-byte sectors and 32K/64K-byte blocks, allowing flexible erasure options.

Memory IC Feature Summary

• Supports Ultra Low Power Mode and High Performance Mode for optimized energy efficiency and speed.
• Features advanced security including block lock protection and an 8K-bit secured OTP area for unique identifiers.
• Enables Program Suspend/Resume and Erase Suspend/Resume for dynamic system management.
• Provides hardware write protection via the WP# pin and software protection through status register bits.

Memory IC Applications

• Embedded systems requiring non-volatile code storage
• Consumer electronics with limited power budgets
• Industrial control applications needing data retention
• IoT devices utilizing secure identification features

Memory IC Procurement Notes

Verify the specific ordering suffix to confirm package type and temperature range compatibility. Ensure the design accounts for the required voltage levels and interface signals. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Check for any recent product change notices regarding packaging or material composition updates.

Memory IC Selection Notes

Select this component when an 8-Mbit capacity is required in a compact USON package. Consider the MX25R series for its balance of low power consumption and moderate performance. Evaluate the need for Quad I/O speeds versus standard SPI interfaces. Ensure the application benefits from the integrated security features and flexible block protection schemes.

Memory IC Part Context

This part belongs to the MX25R8035F family, which includes various package options such as SOP, WSON, and WLCSP. The ZUIH0 suffix specifically denotes the 8-land USON (2x3mm) package variant. It shares core electrical specifications and command sets with other members of the MXSMIO series, differing primarily in physical footprint and pin configuration.

Memory IC Replacement Considerations

Direct replacements within the same family include other MX25R8035F variants with different packages, such as MX25R8035FM1IL0 for SOP-8 or MX25R8035FBHIH2 for WLCSP. Verify that the substitute part matches the required operating voltage range and interface timing characteristics before integration.
