MT46H256M32L4JV-5 IT:B TR

Memory IC Overview

The Micron MT46H256M32L4JV-5IT:B TR is a Mobile Low-Power DDR SDRAM IC with an 8Gb capacity organized as 256 Meg x 32. It utilizes a 168-ball VFBGA package measuring 12mm x 12mm. The device operates at a clock rate of 200 MHz with a cycle time of 5ns and an access time of 5.0ns. Supply voltage ranges from 1.70V to 1.95V, supporting an operating temperature range of -25°C to +85°C.

Memory IC Feature Summary

• Internal pipelined double data rate architecture enabling two data accesses per clock cycle
• Four internal banks for concurrent operation with programmable burst lengths
• Bidirectional data strobe per byte with edge-aligned reads and center-aligned writes
• Supports partial-array self refresh and deep power-down modes

Memory IC Applications

• Mobile handheld devices requiring low-power memory
• Wireless communication equipment
• Portable consumer electronics

Memory IC Procurement Notes

Verify the specific ordering suffix IT:B TR against official Micron documentation to confirm the wireless temperature rating, design revision, and tape-and-reel packaging format. Ensure compatibility with system voltage requirements and interface standards before procurement.

Memory IC Selection Notes

Select this component for applications requiring high-speed mobile memory with extended temperature capabilities. Confirm that the 168-ball VFBGA footprint matches the PCB layout and that the 5ns timing meets the system's clock frequency requirements.

Memory IC Part Context

This part belongs to the Micron Mobile LPDDR family, designed for portable electronics. It shares architectural features with other variants in the series but differs in capacity, package type, and speed grade. The L4 addressing indicates a standard four-die stack configuration.

Memory IC Replacement Considerations

Check for compatible parts within the same Micron Mobile LPDDR family with matching pinout and electrical specifications. Verify that any substitute supports the required 168-ball VFBGA package and -25°C to +85°C operating range.
