This document describes Micron's synchronous DRAM product MT48H8M16LF, which features temperature compensated self refresh, fully synchronous operation, internal pipelined operation, and hiding row access/precharge.
The Micron MT48H8M16LF is a 128 Mb (x16) mobile SDRAM built on a 54‑ball FBGA package (8 mm × 8 mm). It operates at 1.8 V and supports temperature ranges from –25 °C to +85 °C (extended) or –40 °C to +85 °C (industrial). The device offers fully synchronous operation with programmable burst lengths, auto‑precharge, and multiple power‑saving modes.
Key functional blocks include a quad‑bank architecture, internal pipelined operation, and LVITL‑compatible I/O. Detailed timing diagrams, mode register definitions, and command descriptions are provided for system integration and initialization procedures.
