MT46V32M16TG-5B:F TR

Memory IC Overview

The MT46V32M16TG-5B:F TR is a 512 Mbit Double Data Rate SDRAM manufactured by Micron Technology. It features an 8 Meg x 16 organization with four internal banks and operates at a maximum clock frequency of 133 MHz (PC3200). The device utilizes a 66-pin TSOP package and supports a data bus width of 16 bits. Power supply requirements are +2.5V ±0.2V for standard operation, or +2.6V ±0.1V for DDR400 speeds. It includes bidirectional data strobes, differential clock inputs, and programmable burst lengths of 2, 4, or 8.

Memory IC Feature Summary

• Internal pipelined double-data-rate architecture enabling two data accesses per clock cycle
• Four internal banks allowing concurrent operations to hide row precharge and activation time
• Source-synchronous data capture using bidirectional data strobes aligned with read and write data
• Supports auto refresh and self-refresh modes for power management

Memory IC Applications

• High-speed computer memory systems
• Graphics applications requiring high bandwidth
• Networking equipment
• Industrial control systems

Memory IC Procurement Notes

Verify the specific suffix 'IT' if industrial temperature range (-40°C to +85°C) is required, as the provided source material lists 'F' revision without explicit temperature designation in the part number breakdown table. Confirm that the 'TR' suffix indicates tape and reel packaging, distinct from tray options. Ensure compatibility with SSTL_2 I/O standards on the target PCB design.

Memory IC Selection Notes

Select this component when a 512 Mbit capacity with a 16-bit interface is necessary for DDR333 or DDR400 applications. Consider the 66-pin TSOP package for through-hole or surface-mount designs where FBGA is unsuitable. Verify that the system supports the required CAS latencies and voltage levels for the -5B speed grade.

Memory IC Part Context

This part belongs to the Micron MT46V32M16 family of 512Mb DDR SDRAMs. It shares architectural features with other variants in the series, such as the MT46V64M8 and MT46V128M4, differing primarily in density and organization. The TG suffix denotes a plastic TSOP package, while F indicates the specific silicon revision compatible with x4, x8, and x16 configurations.

Memory IC Replacement Considerations

Check for MT46V32M16TG-5B:J or MT46V32M16P-5B:F TR as potential pin-compatible alternatives within the same family. Verify timing parameters and voltage specifications before substitution.
