MT47H64M16NF-25E

The Micron MT47H64M16NF-25E is a 1Gb DDR2 SDRAM x16, configured as 8 Meg x 16 x 8 banks, on the -25E speed grade (DDR2-800) at VDD = 1.8V. It is an automotive-grade variant.

Key figures

• Array: 8 Meg x 16 x 8 banks (1Gb, x16).
• Speed: -25E = DDR2-800, CL = 5, cycle time 2.5ns.
• Supply: VDD = VDDQ = 1.8V (JEDEC-standard 1.8V I/O).
• Package: 84-ball FBGA, 8mm x 12.5mm (package code NF).
• Operating temperature range: -40°C to +95°C.

Grade note

The ordering-code suffix decodes to an automotive-grade device (“Automotive grade” special option) on the IT operating range, -40°C to +95°C. The grade is carried through the classification above; this page does not reproduce the qualification standard name in prose. The same data sheet also documents an x8 sibling that is not this ordering code.

Lifecycle

No first-hand lifecycle (PCN/EOL) document was archived here for this code, so the lifecycle field is left blank rather than asserted.
