AT25XE021A-XMHN-T

Memory IC Overview

The AT25XE021A-XMHN-T is a non-volatile flash memory integrated circuit manufactured by Renesas Electronics Corporation. It features a storage capacity of 2 Mbit organized as 256K x 8 bits and utilizes an SPI interface with a clock frequency of 70 MHz. The device operates within a supply voltage range of 1.65V to 3.6V and supports a wide operating temperature range from -40°C to +85°C. It is housed in an 8-TSSOP package (0.173", 4.40mm width) and is designed for surface mount installation.

Memory IC Feature Summary

• Supports Single, Dual, and Quad SPI modes for flexible data transfer rates
• Ultra-low energy consumption architecture suitable for battery-powered applications
• High reliability with robust write protection mechanisms

Memory IC Applications

• Execute-in-Place (XIP) code execution
• System settings and configuration storage
• Datalogging applications
• Boot loader storage

Memory IC Procurement Notes

Verify the specific suffix 'XMHN' corresponds to the 8-TSSOP package and tape & reel packaging format. Confirm that the component meets RoHS3 compliance standards and check for any recent Product Change Notifications (PCN) regarding label implementations or assembly location updates prior to finalizing procurement orders.

Memory IC Selection Notes

Select this component when a balance between low power consumption and moderate speed is required for 2 Mbit storage. Ensure the design accommodates the 8-TSSOP footprint and that the system voltage aligns with the 1.65V to 3.6V operational range. Consider the 70 MHz clock limit for high-speed data access requirements.

Memory IC Part Context

This part belongs to the AT25XE021A series of ultra-low energy serial flash memories. It shares core electrical specifications with variants like the AT25XE021A-MHN-T and AT25XE021A-SSHN-T, differing primarily in the physical package type. The series is engineered for general-purpose code and data storage tasks in embedded systems.

Memory IC Replacement Considerations

Direct pin-compatible substitutes include AT25XE021A-MHN-T (UDFN package) and AT25XE021A-SSHN-T (SOIC package). Verify package dimensions and thermal characteristics before substituting, as mechanical fit may differ despite identical electrical performance.
