MT47H128M16RT-25E is a 2Gb DDR2 SDRAM in a 16 Meg x 16 x 8 banks configuration, on the -25E speed grade (DDR2-800, tCK = 2.5ns, CL = 5) at VDD = VDDQ = 1.8 V, in a 84-ball FBGA package (9.0mm x 12.5mm, package code RT). Operating temperature range: 0C to +85C.
Key figures
- Array: 16 Meg x 16 x 8 banks (2Gb).
- Speed: -25E = DDR2-800, tCK = 2.5ns, CL = 5.
- Supply: VDD = VDDQ = 1.8 V.
- Package: 84-ball FBGA, 9.0mm x 12.5mm (package code RT).
- Operating temperature range: 0C to +85C.
Temperature and lifecycle
The manufacturer part catalog lists this ordering code’s operating range as 0C to +85C, and its part status as “End of Life”, so the Lifecycle field is set to Obsolete on that basis.
Source and datasheet link
Device figures come from Micron 2Gb: x4, x8, x16 2Gb DDR2 SDRAM current commercial-grade part (first-hand Antenna House/micron-ds-fo.xsl, AGG=NONE, the document body is marked Micron Confidential) + Micron ddr2 part-catalog export (2026-11-02); the operating-temperature band and supply status come from the manufacturer part catalog. No public datasheet hyperlink is published (this is a confidential manufacturer copy, not byte-verified against a hosted public file).
Who makes it
Micron Technology, Inc., founded 1978 and headquartered in Boise, Idaho, is the manufacturer of this DDR2 family.
