MT48LC16M16A2BG-7E IT:D

Memory IC Overview

The Micron MT48LC16M16A2BG-7E IT:D is a 256 Mbit Synchronous DRAM organized as 4 Meg x 16 with four internal banks. It operates at a maximum clock frequency of 133 MHz with a cycle time of 7.5 ns and CAS latency of 2. The device uses a single 3.3V power supply and features LVTTL-compatible inputs and outputs. It is housed in a 54-ball VFBGA package (8mm x 14mm) and supports an industrial operating temperature range from -40°C to +85°C.

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
• Includes auto precharge and self-refresh modes for efficient power management

Memory IC Applications

• Personal computer memory systems
• Graphics cards and video acceleration
• Consumer electronics requiring high-speed data buffering

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required timing grade (-7E), package type (BG), temperature rating (IT), and revision level (:D). Confirm lead times and availability directly with authorized distributors, as this component may be subject to end-of-life status or limited production runs.

Memory IC Selection Notes

Select this part when a 16-bit wide interface is required for 256 Mbit capacity. Ensure the host system supports PC133 specifications and 3.3V logic levels. Verify that the 54-ball VFBGA footprint is compatible with the target PCB design and that the industrial temperature range meets environmental requirements.

Memory IC Part Context

This component belongs to the Micron MT48LC16M16A2 series of 256Mb SDR SDRAMs. It is designed for high-performance applications requiring fast data throughput. The series includes various packaging options and speed grades to accommodate different system constraints and form factors.

Memory IC Replacement Considerations

Check for direct pin-to-pin replacements within the same family, such as the MT48LC16M16A2BG-7E IT:G, noting that the revision suffix indicates a change in manufacturing process or documentation version rather than functional differences.
