MT48LC4M32B2F5-6:G

Memory IC Overview

The MT48LC4M32B2F5-6:G is a 128 Mbit Synchronous Dynamic Random Access Memory (SDRAM) manufactured by Micron Technology. It features a 32-bit data bus width and an organization of 1 Megabit x 32 across four internal banks. The device supports a maximum clock frequency of 167 MHz with a typical access time of 5.4 ns. It operates on a single 3.3V power supply within a voltage range of 3.0V to 3.6V. The component is housed in a VFBGA-90 package, suitable for surface mount technology, and functions reliably within an industrial 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 programmable burst lengths including 1, 2, 4, 8, or full page configurations.
• Includes auto precharge and concurrent auto precharge modes for efficient row management.

Memory IC Applications

• High-performance personal computer systems requiring fast memory access.
• Graphics workstations utilizing high-bandwidth memory interfaces.
• Networking equipment requiring reliable synchronous data storage.
• Industrial control systems operating within extended temperature ranges.

Memory IC Procurement Notes

Verify the specific suffix :G against official Micron documentation to confirm pinout and electrical characteristics match your design requirements. Confirm current lifecycle status as older SDRAM variants may be discontinued. Ensure compatibility with your system's CAS latency settings and refresh intervals before finalizing procurement.

Memory IC Selection Notes

Select this component when a 32-bit wide interface is required for high-throughput applications. Compare against the MT48LC4M32B2 series for alternative packaging options such as TSOP if board space constraints differ. Verify that the 167 MHz speed grade meets your system clock requirements and that the VFBGA-90 footprint aligns with your PCB layout capabilities.

Memory IC Part Context

This part belongs to the Micron MT48LC family of SDRAM devices, designed for general-purpose high-speed memory applications. It shares architectural similarities with other members like the MT48LC4M32B2B5 but differs in package type and specific speed binning. The F5 designation typically indicates a specific speed grade within the commercial or industrial temperature spectrum.

Memory IC Replacement Considerations

Direct replacements include other MT48LC4M32B2 variants with compatible speed grades and package types. Verify that substitute parts maintain the same 32-bit width and 128 Mbit capacity. Check for identical pinouts in VFBGA-90 packages to ensure mechanical interchangeability without redesigning the motherboard traces.
