MT48LC2M32B2P-6A:J TR

Memory IC Overview

The MT48LC2M32B2P-6A:J TR is a 64Mb Synchronous Dynamic Random Access Memory (SDRAM) manufactured by Micron Technology. It features a 2 Meg x 32 organization with four internal banks and operates at a maximum clock frequency of 167 MHz. The device utilizes an 86-pin TSOP II package and supports LVTTL-compatible inputs and outputs. It requires a single 3.3V ±0.3V power supply and offers programmable burst lengths of 1, 2, 4, 8, or full page. Key timing parameters include a CAS latency of 3-3-3, with tRCD and tRP values of 18 ns.

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
• Supports auto precharge, concurrent auto precharge, and auto refresh modes for efficient row management
• LVTTL-compatible inputs and outputs ensuring compatibility with standard logic levels

Memory IC Applications

• General-purpose memory systems requiring 3.3V operation
• Embedded systems utilizing synchronous DRAM interfaces
• Industrial control applications compatible with commercial temperature ranges
• Consumer electronics devices needing high-speed data buffering

Memory IC Procurement Notes

Verify the specific revision code (:J) against current Micron documentation to ensure alignment with latest manufacturing standards. Confirm that the 86-pin TSOP II package matches your PCB footprint requirements. Check for end-of-life status as older SDRAM variants may be discontinued. Ensure voltage levels strictly adhere to the 3.3V ±0.3V specification during integration.

Memory IC Selection Notes

Select this component when a 64Mb capacity with a 32-bit data bus width is required. The -6A speed grade provides a 167 MHz operating frequency suitable for moderate-speed applications. The industrial temperature range option (IT) should be considered if operation below 0°C is necessary, though the base model covers commercial ranges. Verify CAS latency requirements match the system controller's capabilities.

Memory IC Part Context

This part belongs to the MT48LC2M32B2 series of 64Mb SDR SDRAMs. It shares architectural similarities with other members like the MT48LC2M32B2TG and MT48LC2M32B2B5, differing primarily in package type and speed grade. The series is designed for PC100-compliant systems and offers internal bank interleaving to hide row access times.

Memory IC Replacement Considerations

Direct substitutes include the MT48LC2M32B2P-6A without the trailing suffix if packaging differences are negligible. For identical specifications, verify availability of the MT48LC2M32B2P-6A IT:J TR variant. Cross-reference with other manufacturers' 64Mb x32 SDRAMs only after confirming pinout and electrical parameter compatibility.
