MT48LC4M16A2TG-6:G

Memory IC Overview

The MT48LC4M16A2TG-6:G is a 64Mb SDRAM manufactured by Micron Technology. It features a 4 Meg x 16 organization with four internal banks. The device operates at a maximum clock frequency of 166 MHz and has an access time of 5.5 ns. It uses a 54-pin TSOP II package and requires a single +3.3V ±0.3V power supply. The component supports PC100 and PC133 standards, includes LVTTL-compatible inputs/outputs, and offers standard and low-power self-refresh modes.

Memory IC Feature Summary

• Fully synchronous interface with all signals registered on the positive edge of the system clock
• Internal pipelined architecture allowing column address changes every clock cycle for high-speed random access
• Quad-bank structure enabling concurrent operations to hide row access and precharge times
• Programmable burst lengths including 1, 2, 4, 8, or full page with sequential or interleaved types

Memory IC Applications

• High-performance computer memory systems
• Graphics and video display buffers
• Embedded systems requiring fast data access
• Networking equipment memory modules

Memory IC Procurement Notes

Verify the specific speed grade suffix (-6) and package type (TG) against current Micron datasheets to ensure compatibility with target system timing requirements. Confirm that the -6 grade meets the 166 MHz operational frequency needed for your design. Check for end-of-life status as older SDRAM variants may be discontinued.

Memory IC Selection Notes

Select this part for designs requiring a 16-bit wide data bus and 64Mb capacity in a compact TSOP package. Ensure the host controller supports the required initialization sequence and mode register programming. Verify that the 3.3V operating voltage aligns with the system power rails and that the 5.5 ns access time satisfies the system clock constraints.

Memory IC Part Context

This component belongs to the Micron MT48LC series of 64Mb SDRAMs, which also includes x4 and x8 configurations. The MT48LC4M16A2 variant specifically provides a 16-bit data path, distinguishing it from the narrower bus options in the same family while sharing identical internal bank structures and command sets.

Memory IC Replacement Considerations

Compatible substitutes include other Micron MT48LC4M16A2 variants with different speed grades or packages, such as MT48LC4M16A2P-7E or MT48LC4M16A2TG-75, provided timing parameters are verified.
