MT47H128M16RT-25E IT:C

Product Overview

The MT47H128M16RT-25E IT:C is a Micron Technology Inc. DDR2 SDRAM memory IC offering 2Gbit of volatile DRAM in an 84-FBGA surface-mount package. It is organized as 128M x 16 and uses a parallel memory interface with a 400 MHz clock frequency. The device is specified for a 1.7V to 1.9V supply voltage and an operating temperature range of -40°C to 95°C (TC), making it suitable for board-level memory subsystems that require a parallel DDR2 interface.

Key Features

• 2Gbit volatile DRAM memory capacity
• 128M x 16 memory organization with parallel interface
• DDR2 technology with 400 MHz clock frequency
• 400 ps access time and 15 ns word/page write cycle time
• 1.7V to 1.9V supply voltage range
• -40°C to 95°C (TC) operating temperature
• 84-TFBGA surface-mount package, supplier device package 84-FBGA (9x12.5)

Applications

• System memory for DDR2-compatible computing platforms
• Buffer memory in embedded designs using a parallel DDR2 interface
• High-density volatile storage in memory modules and board-level subsystems

Design & Procurement Notes

Design reviews should confirm that the memory controller supports a parallel DDR2 interface, 128M x 16 organization, and 400 MHz operation. The 1.7V to 1.9V supply range requires regulated board power with adequate decoupling and stable voltage margins. PCB layout should account for the 84-FBGA (9x12.5) surface-mount package and the parallel signal paths. Thermal design should consider the -40°C to 95°C (TC) operating range, including case temperature measurement or simulation. Timing budgets can reference the 400 ps access time and 15 ns word/page write cycle time when validating system performance.
