MT48LC8M16A2P-7E IT:L TR

Memory IC Overview

The MT48LC8M16A2P-7E IT:L TR is a Micron Technology 128Mb Synchronous DRAM configured as 8 Meg x 16 with four internal banks. It operates at a maximum clock frequency of 143 MHz with a cycle time of 7ns and an access time of 5.4ns. The device uses a single +3.3V ±0.3V power supply and features LVTTL-compatible inputs and outputs. It supports programmable burst lengths of 1, 2, 4, or 8 locations, along with auto precharge and self-refresh modes. The component is housed in a 54-pin TSOP II package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

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
• Quad-bank organization enabling row access hiding for seamless random-access operation
• Supports standard and low-power self-refresh modes alongside auto refresh capabilities

Memory IC Applications

• High-speed data buffering in embedded systems
• Cache memory expansion for microprocessors
• Graphics frame buffer applications
• Industrial control system memory modules

Memory IC Procurement Notes

Verify that the ordering suffix 'IT' confirms the industrial temperature range (-40°C to +85°C) and 'L' indicates low-power self-refresh support. Confirm the 'TR' suffix aligns with the required tape-and-reel packaging format for automated assembly processes. Ensure compatibility with the host controller's voltage levels and timing constraints before finalizing procurement.

Memory IC Selection Notes

Select this part when a 128Mb capacity with a 16-bit data bus width is required for high-performance synchronous operations. The -7E speed grade is suitable for systems requiring up to 143 MHz clock frequencies. Choose the industrial temperature variant if the application environment exceeds commercial limits. Verify that the 54-pin TSOP II package fits the available PCB footprint and routing constraints.

Memory IC Part Context

This component belongs to the Micron MT48LC8M16A2 series of 128Mb SDRAMs. It shares architectural similarities with other members like the MT48LC16M8A2 and MT48LC32M4A2, differing primarily in organization and pinout. The device is designed for PC100 and PC133 compliant systems, offering a cost-effective solution for general-purpose memory needs in consumer and industrial electronics.

Memory IC Replacement Considerations

Direct replacements include other Micron parts within the same family such as the MT48LC8M16A2TG-7E for leaded TSOP variants. Cross-manufacturer equivalents may require verification of pin compatibility and timing parameters. Ensure any substitute maintains the 16-bit width and 143MHz operational capability.
