MT48H8M32LFB5-10 TR

Memory IC Overview

The Micron MT48H8M32LFB5-10 TR is a 256Mb Mobile SDRAM configured as 2 Meg x 32 with four internal banks. It operates at VDD/VDDQ of 1.70–1.95V in a 90-ball VFBGA (8mm x 13mm) package. The -10 speed grade supports clock rates up to 100 MHz, featuring an access time of 9ns and data setup/hold times of 2.5ns and 1ns respectively at CAS latency 2. It includes industrial temperature rating (-40°C to +85°C), partial-array self refresh, deep power-down, and LVTTL-compatible I/O.

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 for high-speed random access
• Supports programmable burst lengths including continuous page mode and auto precharge functions
• Includes low-power modes such as Deep Power-Down (DPD) and Partial-Array Self Refresh (PASR)

Memory IC Applications

• Mobile handheld devices requiring compact memory solutions
• Portable consumer electronics utilizing mobile SDRAM interfaces
• Industrial embedded systems operating within extended temperature ranges

Memory IC Procurement Notes

Verify the specific ordering suffix against official Micron documentation to confirm package type, speed grade, and temperature range. Ensure compatibility with existing system clock frequencies and voltage requirements before integration. Confirm availability status as older mobile SDRAM generations may have limited supply chains or end-of-life implications.

Memory IC Selection Notes

Select this component when a 32-bit data bus width is required for mobile applications. The 90-ball VFBGA package suits designs needing higher density than the 54-ball variant. Verify that the host controller supports the necessary CAS latencies and burst configurations defined in the mode register settings for optimal performance.

Memory IC Part Context

This device belongs to Micron's 256Mb Mobile SDRAM family, designed for low-power portable applications. It shares architectural similarities with the MT48H16M16LF but offers a wider 32-bit interface. The part utilizes standard synchronous DRAM protocols compatible with common mobile processors and baseband chips.

Memory IC Replacement Considerations

Direct substitutes include other Micron 256Mb Mobile SDRAM parts with matching 32-bit organization and VFBGA packages, such as the MT48H8M32LBF5 series. Cross-vendor replacements require verification of pinout compatibility and timing parameters.
