MT48LC16M16A2TG-75 L:D TR

Memory IC Overview

The Micron MT48LC16M16A2TG-75 L:D TR is a 256 Mbit Synchronous Dynamic Random Access Memory (SDRAM) configured as 16 Meg x 16 bits across four internal banks. It operates at a maximum clock frequency of 133 MHz with a cycle time of 7.5 ns and a CAS latency of 3. The device utilizes a single +3.3V ±0.3V power supply and features a 54-pin Thin Small Outline Package (TSOP II). It supports programmable burst lengths of 1, 2, 4, or 8 and includes low-power self-refresh capabilities.

Memory IC Feature Summary

• Fully synchronous operation with all signals registered on the positive edge of the system clock
• Internal pipelined architecture allowing column address changes every clock cycle
• Supports low-power self-refresh mode for reduced standby current consumption
• Compatible with PC100 and PC133 standards for standard memory interface compliance

Memory IC Applications

• Personal computer main memory systems
• Graphics frame buffer storage
• Industrial control board memory modules
• Consumer electronics requiring volatile data retention

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, speed grade, and temperature range. Confirm whether the 'L' designation indicates low-power self-refresh availability for the target application environment. Ensure the revision level aligns with existing design documentation to prevent potential timing discrepancies during integration.

Memory IC Selection Notes

Select this component when a 16-bit wide interface is required for 256 Mbit capacity within a TSOP II footprint. Consider the -75 speed grade for systems operating up to 133 MHz. Evaluate the low-power self-refresh feature if extended battery life or thermal management in enclosed industrial environments is a priority over standard refresh modes.

Memory IC Part Context

This part belongs to the Micron MT48LC16M16A2 series, which provides 256 Mbit density options in various configurations including x4, x8, and x16. The series is designed for general-purpose synchronous DRAM applications, offering flexibility through multiple package options such as TSOP and FBGA variants to suit different PCB layout constraints.

Memory IC Replacement Considerations

Direct replacements include other Micron parts from the same family with matching speed grades and packages, such as the MT48LC16M16A2P-75 variant. Verify pinout compatibility and electrical specifications before substituting.
