MT28EW256ABA1HPN-0SIT TR

Memory IC Overview

The MT28EW256ABA1HPN-0SIT TR is a 256 Mbit NOR flash memory component from Micron Technology Inc. It features an asynchronous parallel interface with support for 32M x 8 or 16M x 16 bit organization. The device operates within a voltage range of 2.7V to 3.6V and offers access times of 70 ns. It is housed in a VFBGA-56 package, suitable for surface mount installation, and functions across a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports asynchronous parallel data transfer with flexible bus width configurations
• Provides non-volatile storage using SLC NAND technology architecture
• Designed for embedded applications requiring high-speed random access

Memory IC Applications

• Embedded systems firmware storage
• Industrial control equipment code execution
• Automotive electronics boot code retention

Memory IC Procurement Notes

Verify the specific suffix HPN against official Micron documentation to confirm the VFBGA-56 package type and pinout compatibility. Ensure the trailing TR designation aligns with reel handling requirements for automated assembly processes. Cross-reference the full part number with current datasheets to validate operational parameters and environmental ratings before integration into design specifications.

Memory IC Selection Notes

Select this component when a parallel interface is required for direct CPU connection without external controllers. The VFBGA-56 package offers a compact footprint compared to larger BGA options. Consider the 70 ns access speed for system timing constraints. Verify that the 2.7V to 3.6V supply range matches the target platform's power delivery capabilities.

Memory IC Part Context

This part belongs to the MT28EW series of embedded parallel NOR flash memories. It provides a balance of density and performance for code execution in resource-constrained environments. The series supports standard parallel commands for read, program, and erase operations, facilitating straightforward integration into existing hardware architectures designed for parallel NOR devices.

Memory IC Replacement Considerations

MT28EW256ABA1HPC-0SIT TR: Offers identical electrical specifications but utilizes a 64-LBGA package instead of VFBGA-56. Requires PCB layout modification for different pinout and dimensions.
