512 Mbit DDR2 SDRAM for industrial-temperature memory subsystems
The Micron MT47H32M16NF-25E IT:H is a 512 Mbit DDR2 SDRAM organized as 32M x 16, clocked at 400 MHz with a 400 ps access time. It operates from a 1.7 V to 1.9 V supply and is rated for -40°C to 95°C (TC).
Industrial temperature grade — no derating guesswork
The -40°C to 95°C (TC) range covers the full industrial temperature envelope with case-temperature referencing. No separate screening or derating is needed for outdoor enclosures, unheated cabinets, or near-engine installations. The 15 ns write cycle time (word, page) is maintained across the full temperature span.
