MT48LC4M16A2P-75:G TR

Memory IC Overview

The Micron MT48LC4M16A2P-75:G TR is a 64Mb SDRAM configured as 4 Meg x 16, housed in a 54-pin TSOP II package. It operates at a maximum clock frequency of 133 MHz with a cycle time of 7.5 ns and an access time of 5.4 ns. The device uses a single +3.3V power supply and supports burst lengths of 1, 2, 4, or 8. It features four internal banks for interleaved operations and includes 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
• Programmable burst lengths including sequential and interleaved types
• Supports auto precharge and concurrent auto precharge functions

Memory IC Applications

• Embedded systems requiring high-speed memory
• Consumer electronics utilizing 3.3V logic
• Industrial control applications within commercial temperature ranges

Memory IC Procurement Notes

Verify the specific suffix :G indicates die revision G and P denotes lead-free plastic packaging. Confirm the -75 grade corresponds to 133 MHz operation. Ensure the TR designation matches the required reel quantity for manufacturing. Check RoHS compliance status against current regulatory requirements.

Memory IC Selection Notes

Select this component when a 16-bit data bus width is required for 64Mb capacity. The 133 MHz speed grade suits designs needing moderate latency. The TSOP II package is suitable for surface mount assembly where space constraints allow its dimensions. Verify controller compatibility with the specified CAS latencies.

Memory IC Part Context

This part belongs to the Micron MT48LC series of 64Mb SDRAMs. It shares architectural similarities with the MT48LC16M4A2 and MT48LC8M8A2 variants, differing primarily in organization and pinout. The series supports PC66, PC100, and PC133 standards.

Memory IC Replacement Considerations

Direct replacements include other Micron parts from the same family such as the MT48LC4M16A2TG-75:G if tape-and-reel packaging is not strictly required. Cross-vendor equivalents must match the 4Mx16 organization, 54-pin TSOP package, and 133MHz timing specifications.
