MT48LC4M32B2F5-7 IT:G TR

Memory IC Overview

The MT48LC4M32B2F5-7 IT:G TR is a 128 Mbit Synchronous Dynamic Random Access Memory (SDRAM) manufactured by Micron Technology. It features a 32-bit data bus width and an organization of 1 Meg x 32 across four internal banks. The device supports PC100 compliance with a maximum clock frequency of 143 MHz and a typical access time of 7 ns. It operates on a single 3.3V ±0.3V power supply and supports CAS latencies of 1, 2, and 3. The component utilizes Low Voltage Transistor-Transistor Logic (LVTTL) compatible inputs and outputs.

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 programmable burst lengths including 1, 2, 4, 8, or full page configurations.
• Includes auto precharge and concurrent auto precharge modes for efficient row management.

Memory IC Applications

• Personal computer memory systems
• Graphics cards and video acceleration
• Consumer electronics requiring high-speed data buffering

Memory IC Procurement Notes

Verify the specific suffix 'IT:G' against official Micron documentation to confirm temperature range and packaging details. Ensure the ordering information matches the exact part number to avoid compatibility issues with system controllers. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement.

Memory IC Selection Notes

Select this component when a 128 Mbit capacity with a 32-bit interface is required for PC100-compliant designs. Consider the four-bank architecture for improved performance in applications needing row access hiding. Verify that the controller supports the necessary CAS latency settings and burst length configurations defined in the device specifications.

Memory IC Part Context

This device belongs to the MT48LC4M32B2 family of 128 Mbit SDRAMs. Variants within this family share the same core memory array but differ in speed grades, package types, and environmental ratings. The F5 designation typically indicates a specific package configuration within the broader product line.

Memory IC Replacement Considerations

Direct replacements include other Micron MT48LC4M32B2 variants with matching speed grades and pinouts. Cross-manufacturer equivalents must be verified for electrical compatibility and timing parameters.
