MT48H8M16LFF4-8 IT

Memory IC Overview

The Micron MT48H8M16LFF4-8 IT is a 128Mb Mobile SDRAM configured as 8 Meg x 16 with four internal banks. It operates at VDD/VDDQ of 1.70V to 1.95V and supports clock frequencies up to 125 MHz (cycle time 8ns). The device utilizes a 54-ball VFBGA package measuring 8mm x 8mm. It features an industrial temperature range of -40°C to +85°C, LVTTL-compatible I/O, and includes power-saving modes such as deep power-down and partial-array self-refresh.

Memory IC Feature Summary

• Fully synchronous interface with internal pipelined architecture for high-speed random access
• On-die temperature sensor enables temperature-compensated self-refresh operation
• Partial-array self-refresh capability allows programmable power reduction during standby
• Quad-bank organization hides row precharge cycles through concurrent bank operations

Memory IC Applications

• Mobile handheld devices requiring low-power memory solutions
• Industrial embedded systems operating in extreme temperature environments
• Portable consumer electronics utilizing 1.8V logic interfaces
• Battery-powered applications benefiting from deep power-down modes

Memory IC Procurement Notes

Verify the exact suffix configuration against official Micron documentation, as 'LFF4' may indicate specific die or packaging variations not explicitly detailed in standard public datasheets. Confirm availability status directly with the manufacturer, as this component series may be subject to discontinuation or lifecycle changes. Ensure compatibility with system voltage levels and thermal requirements before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when designing systems that require 128Mb capacity within a compact 54-ball footprint. It is suitable for applications needing industrial-grade temperature stability and low-power standby modes. Consider the 8ns cycle time for timing constraints relative to the host processor's clock speed. Verify that the system supports the required 1.8V supply rails and LVTTL signaling standards.

Memory IC Part Context

This part belongs to the Micron Mobile SDRAM family, designed specifically for portable and mobile applications. It represents a generation of low-power synchronous DRAMs optimized for battery life and space-constrained designs. The technology focuses on reducing power consumption through advanced self-refresh techniques while maintaining high data throughput capabilities.

Memory IC Replacement Considerations

Consult Micron's official cross-reference guides for verified substitutes. Potential alternatives include other parts within the MT48H8M16LF series with different speed grades or temperature ratings. Ensure any replacement maintains the same 54-ball VFBGA pinout and electrical characteristics to guarantee board-level compatibility.
