MT46V64M8FN-6:D TR

Memory IC Overview

The MT46V64M8FN-6:D TR is a 512Mb DDR SDRAM configured as 16 Meg x 8 with four internal banks. It utilizes a 60-ball FBGA package (10mm x 12.5mm) and operates at a clock rate of 167 MHz with a cycle time of 6ns. The device supports CAS latencies of 2.5, features a pipelined double-data-rate architecture for two data accesses per clock cycle, and includes bidirectional data strobes (DQS). It requires VDD and VDDQ supplies of +2.5V ±0.2V.

Memory IC Feature Summary

• Internal pipelined double-data-rate architecture enabling two data accesses per clock cycle
• Four internal banks allowing for concurrent operation to maximize effective bandwidth
• Source-synchronous data capture using bidirectional data strobes (DQS)
• Supports programmable burst lengths of 2, 4, or 8 locations

Memory IC Applications

• High-speed computer systems requiring dynamic random-access memory
• Graphics applications utilizing SDRAM interfaces
• Networking equipment needing high-bandwidth data storage
• Consumer electronics devices incorporating DDR memory solutions

Memory IC Procurement Notes

Verify the specific speed grade suffix '6' corresponds to the required 6ns cycle time and 167 MHz operation. Confirm the 'FN' designation matches the 60-ball FBGA package dimensions. Ensure the ':D' revision aligns with design requirements. Check RoHS compliance status as standard versions may differ from lead-free variants. Validate that the 'TR' suffix indicates tape-and-reel packaging for automated assembly processes.

Memory IC Selection Notes

Select this component when a 512Mb density with an 8-bit data bus width is required. The 6ns speed grade suits systems operating at 167 MHz. Consider the FBGA package for space-constrained designs. Verify voltage compatibility with the +2.5V supply requirement. Ensure the controller supports the necessary CAS latency settings for the selected speed grade.

Memory IC Part Context

This part belongs to Micron's 512Mb DDR SDRAM family, which also includes x4 and x16 configurations. The MT46V64M8 series shares architectural features with the MT46V128M4 and MT46V32M16 variants. These components utilize the same Core DDR Rev. B technology and offer similar feature sets including DLL alignment and differential clock inputs.

Memory IC Replacement Considerations

Compatible substitutes within the same family include other speed grades like -5B or -75 if timing constraints allow. Different package options such as TSOP are available but require board redesign. Cross-vendor equivalents must match the 512Mb density, 8-bit width, and FBGA footprint.
