MT47H128M4CF-3:F – DDR2 SDRAM – Micron

Micron MT47H128M4CF-3:F is a 512Mb DDR2-667 SDRAM organized as 256 Meg x 4 (32 Meg x 4 x 4 banks) in a Pb-free 60-ball FBGA package (8mm x 10mm). This obsolete, hard-to-find part is available now for RFQ at Pacific Component Xchange.

The Micron MT47H128M4CF-3:F is a 512-megabit DDR2 SDRAM from Micron’s MT47H legacy DRAM family. It is organized as 256 Meg x 4 (32 Meg x 4 x 4 internal banks) and is rated at the -3 speed grade, DDR2-667 (3.0ns cycle time at CAS latency CL=5), delivering a 667 MT/s data rate at a 333 MHz clock. The device operates from a JEDEC-standard 1.8V supply with SSTL_18-compatible I/O and is supplied in a lead-free (Pb-free) 60-ball FBGA package measuring 8mm x 10mm (package code CF).

As a x4 device, the MT47H128M4CF-3:F is most commonly used in memory modules and embedded designs where multiple narrow-width DRAMs are combined to build wider data buses with ECC support. With Micron’s DDR2 SDRAM line now obsolete, this part is increasingly difficult to source through authorized channels, making it a frequent target for end-of-life buys and legacy production sustainment.
