MT48LC4M16A2B4-6A:J TR

Memory IC Overview

The MT48LC4M16A2B4-6A:J TR is a Micron Synchronous DRAM (SDRAM) component with a total storage capacity of 64 Mbit. It features a data bus width of 16 bits and an organization of 4 Meg x 16 across four internal banks. The device supports a maximum clock frequency of 167 MHz, corresponding to PC133 compliance, with a typical access time of 5.4 ns. It operates within a voltage range of 3 V to 3.6 V and utilizes a VFBGA-54 surface-mount package.

Memory IC Feature Summary

• Fully synchronous operation with all signals registered on the positive edge of the system clock for precise timing control.
• Internal pipelined architecture allows column address changes every clock cycle to maximize throughput efficiency.
• Supports programmable burst lengths including 1, 2, 4, 8, or full page modes for flexible data transfer patterns.
• Includes Auto Precharge and Concurrent Auto Precharge modes to optimize row access and precharge cycles.

Memory IC Applications

• Personal computer memory modules requiring PC100 or PC133 compliant SDRAM
• Graphics cards utilizing SDRAM for frame buffer storage
• Embedded systems needing low-voltage synchronous memory solutions

Memory IC Procurement Notes

Verify the specific suffix ':J TR' against official Micron documentation to confirm tape-and-reel packaging details and RoHS compliance status. Ensure the ordering information matches the exact electrical specifications required for your design, as minor suffix variations can indicate different temperature grades or packaging formats.
