AT25XV041B-MHV-Y

Memory IC Overview

The AT25XV041B-MHV-Y is a 4 Mbit SPI NOR flash memory manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 1.65 V to 4.4 V and supports clock frequencies up to 85 MHz. The device utilizes an 8-UDFN (5x6 mm) package with exposed pad for surface mount installation. It functions across a temperature range of -40°C to +85°C and features non-volatile storage architecture.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI interface modes for flexible data transfer
• Includes security register pages for unique device serialization and key storage
• Optimized erase block sizes for efficient code and data storage operations

Memory IC Applications

• Embedded system code execution via execute-in-place (XiP)
• Data logging in industrial control systems
• Firmware storage for IoT devices

Memory IC Procurement Notes

Verify the suffix 'Y' against official Renesas documentation to confirm specific tape-and-reel packaging or environmental compliance status. Ensure the ordering part number matches the exact electrical specifications required for your design, as suffixes often denote critical manufacturing variations.

Memory IC Selection Notes

Select this component when a wide voltage range including 1.65 V is required alongside standard 3.3 V operation. The 8-UDFN package offers a compact footprint suitable for space-constrained designs. Confirm compatibility with existing SPI controller interfaces supporting dual and quad I/O modes.

Memory IC Part Context

This part belongs to the AT25XV series of SPI NOR flash memories designed for general-purpose data and code storage. It shares architectural similarities with other members like the AT25XE and AT25SF series but distinguishes itself through its extended voltage support down to 1.65 V.

Memory IC Replacement Considerations

Direct substitutes include AT25XV041B-MHV-T. Verify pinout and command set compatibility before replacing.
