MT48LC8M16LFF4-8 XT:G

Memory IC Overview

The MT48LC8M16LFF4-8 XT:G is a 128Mb Mobile SDRAM manufactured by Micron Technology. It features an 8 Meg x 16 organization with four internal banks and operates at a maximum clock frequency of 125 MHz, corresponding to a cycle time of 8ns. The device utilizes a 54-ball VFBGA package measuring 8mm x 8mm. It supports standard and low-power self-refresh modes, temperature-compensated self-refresh (TCSR), and partial-array self-refresh (PASR). The component uses LVTTL-compatible inputs and outputs with a single +3.3V power supply.

Memory IC Feature Summary

• Temperature-compensated self-refresh (TCSR) for stable operation across varying thermal conditions
• Partial-array self-refresh (PASR) capability to reduce power consumption during standby
• Internal pipelined architecture allowing column address changes every clock cycle
• Four internal banks enabling row access/precharge hiding for seamless random access

Memory IC Applications

• Mobile communication devices requiring low power consumption
• Portable consumer electronics utilizing mobile memory architectures
• Industrial systems operating within specified temperature ranges
• Automotive infotainment and control modules

Memory IC Procurement Notes

Verify the specific ordering suffixes against the manufacturer's current datasheet to confirm voltage levels, package type, and temperature grade. Ensure compatibility with system clock frequencies and refresh requirements before integration. Cross-reference part markings with official decoders to validate authenticity and revision status.

Memory IC Selection Notes

Select this component for applications demanding high-speed synchronous data transfer in space-constrained mobile designs. Consider the 54-ball VFBGA footprint for compact board layouts. Evaluate power management needs regarding TCSR and PASR features for battery-operated devices. Confirm interface voltage compatibility with the host controller.

Memory IC Part Context

This part belongs to the Micron 128Mb Mobile SDRAM family, which includes x16 and x32 configurations. It shares architectural similarities with other MT48LC series devices but is optimized for mobile environments. The LF designation indicates the lead-free variant within the VFBGA package options.

Memory IC Replacement Considerations

Compatible substitutes include other Micron 128Mb Mobile SDRAMs with matching speed grades and package types, such as variants ending in -75M or -10, provided timing parameters align with system requirements.
