MT48LC16M4A2P-7E:G

Memory IC Overview

The Micron MT48LC16M4A2P-7E:G is a 64Mb SDRAM with a 4 Meg x 16 organization and 54-pin TSOP package. It supports PC133 compliance at 133 MHz with CAS latency 2, featuring a 5.4 ns access time. Operating on a single +3.3V supply, it includes four internal banks for interleaved access, programmable burst lengths, and standard/low-power self-refresh modes.

Memory IC Feature Summary

• Fully synchronous interface with all signals registered on the positive clock edge
• Internal pipelined architecture allowing column address changes every clock cycle
• Four internal banks to hide row access and precharge times
• Programmable burst lengths of 1, 2, 4, 8, or full page

Memory IC Applications

• High-speed data buffering in embedded systems
• Graphics memory applications requiring random access
• General-purpose volatile storage in 3.3V logic systems

Memory IC Procurement Notes

Verify the specific speed grade suffix matches the required system clock frequency. Confirm that the plastic package variant aligns with thermal and mechanical constraints. Ensure the die revision corresponds to the intended manufacturing batch for compatibility.

Memory IC Selection Notes

Select this component when a 16-bit wide interface is required for 64Mb capacity. The -7E suffix indicates suitability for 133 MHz operation with CAS latency 2. Verify power supply stability within the ±0.3V tolerance for reliable LVTTL signal integrity.

Memory IC Part Context

This device belongs to the Micron 64Mb SDRAM family, which also includes x4 and x8 configurations. It utilizes a quad-bank architecture common to this generation of synchronous DRAMs, designed for high-performance computing environments requiring low-latency access.

Memory IC Replacement Considerations

Compatible substitutes include other Micron 64Mb SDRAMs with identical pinouts and timing, such as the MT48LC16M4A2TG-7E:G (lead-containing) or variants with different temperature ranges like the IT designation.
