AT25DF041B-MHNHR-T

Memory IC Overview

The AT25DF041B-MHNHR-T is a non-volatile NOR flash memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 4 Megabits organized as 512K x 8 bits. The device utilizes an SPI interface with a maximum clock frequency of 85 MHz. It operates within a supply voltage range of 1.7V to 3.6V and supports a commercial temperature range from -40°C to 125°C. The component is housed in an 8-UDFN (2x3) package with exposed pad for surface mount installation.

Memory IC Feature Summary

• Supports standard SPI serial communication protocols for data access
• Provides reliable non-volatile data retention without power
• Designed for high-speed code execution and data storage applications

Memory IC Applications

• Embedded system code storage
• Data logging devices
• Consumer electronics firmware storage

Memory IC Procurement Notes

Verify the specific suffix MHNHR-T against the official Renesas datasheet to confirm the 85 MHz speed grade, 1.7V minimum voltage, and 8-UDFN package type. Ensure the supplier provides RoHS3 compliance documentation. Confirm the manufacturer is Renesas Electronics Corporation or an authorized licensee. Check for recent Product Change Notifications regarding labeling or packaging updates.

Memory IC Selection Notes

Select this component when a compact 8-lead footprint is required alongside extended industrial temperature capabilities up to 125°C. The 85 MHz speed offers a balance between performance and power consumption compared to higher-speed variants. Verify that the system power rail remains stable above 1.7V during operation to ensure correct device functionality.

Memory IC Part Context

This part belongs to the AT25DF041B family of SPI Flash memories. It shares architectural similarities with other members like the AT25DF041B-MAHN-T but differs in speed grade and operating voltage specifications. The family is designed for cost-effective storage solutions in space-constrained electronic designs requiring robust data integrity.

Memory IC Replacement Considerations

Direct pin-compatible substitutes may include other AT25DF041B variants with matching package and speed grades. Verify electrical parameters such as voltage range and temperature limits before substitution.
