MT48LC16M16A2P-7E IT:D TR

Memory IC Overview

The Micron MT48LC16M16A2P-7E IT:D TR is a 256 Mbit Synchronous Dynamic Random Access Memory (SDRAM) component. It features a 16 Meg x 16 organization with four internal banks and a 16-bit data bus width. The device operates at a maximum clock frequency of 133 MHz, corresponding to a cycle time of 7.5 ns at CAS Latency (CL) 2. It utilizes a 54-pin Thin Small Outline Package (TSOP II) in surface-mount configuration. The unit supports an industrial operating temperature range from -40°C to +85°C and requires a single 3.3V ±0.3V power supply.

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 access modes.
• Includes auto precharge functionality with concurrent auto precharge and auto refresh capabilities.

Memory IC Applications

• Industrial embedded systems requiring wide data buses
• Consumer electronics utilizing PC133 compliant memory architectures
• General-purpose digital signal processing applications

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, speed grade, and temperature rating. Confirm the revision status (D or G) as it dictates available packaging options. Ensure the source is an authorized distributor to guarantee product authenticity and traceability. Check for lead times and availability directly with the manufacturer or authorized partners.

Memory IC Selection Notes

Select this component when a 16-bit interface and 133 MHz synchronous performance are required within an industrial temperature environment. Compare against other speed grades if higher frequencies are needed, or different organizations if narrower buses suffice. Verify compatibility with the host controller's supported CAS latencies and burst lengths.

Memory IC Part Context

This part belongs to the Micron MT48LC16M16A2 series of 256 Mbit SDRAM devices. The series offers multiple configurations including x4, x8, and x16 densities. Variations exist across commercial, industrial, and automotive temperature ranges, alongside different physical packages such as TSOP and FBGA types.

Memory IC Replacement Considerations

Direct replacements include other speed grades within the same family, such as the MT48LC16M16A2P-6A for 167 MHz operation or the MT48LC16M16A2P-75 for PC133 CL=3 timing. Cross-package equivalents like the VFBGA version MT48LC16M16A2B4 may be considered if pinout compatibility allows.
