MT48LC16M16A2B4-7E IT:G TR

Memory IC Overview

The MT48LC16M16A2B4-7E IT:G TR is a 256Mb Synchronous DRAM (SDRAM) 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 ±0.3V power supply and features LVTTL-compatible inputs and outputs. It supports standard and low-power self-refresh modes, auto refresh, and programmable burst lengths. The component is housed in a 54-ball VFBGA package and is rated for an industrial operating temperature range of -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 standard and low-power self-refresh modes for reduced power consumption
• Includes auto precharge and concurrent auto precharge capabilities

Memory IC Applications

• Industrial embedded systems requiring wide data bus interfaces
• 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 and temperature grade. Confirm the revision status aligns with design specifications. Ensure compatibility with the host controller's supported SDRAM timing parameters. Validate that the procurement source is authorized by Micron Technology to guarantee product authenticity and traceability.

Memory IC Selection Notes

Select this component when a 16-bit data width and 256Mb capacity are required within an industrial temperature environment. The -7E speed grade provides a 7.5 ns cycle time suitable for 133 MHz systems. Consider the VFBGA package dimensions for PCB layout constraints. Verify that the application does not require automotive-grade certification, which necessitates different part numbering.

Memory IC Part Context

This device belongs to the Micron MT48LC16M16A2 family of 256Mb SDR SDRAMs. It shares architectural similarities with other members like the MT48LC16M16A2P and MT48LC16M16A2FG, differing primarily in package style and thermal characteristics. The B4 suffix indicates the 54-ball VFBGA package variant designed specifically for the x16 configuration.

Memory IC Replacement Considerations

Compatible substitutes include MT48LC16M16A2B4-7E AIT:G TR for automotive temperature ranges or MT48LC16M16A2B4-7E IT:G for standard commercial packages. Cross-referencing requires matching the 16-bit organization, 133 MHz speed grade, and VFBGA footprint.
