MT46H16M16LF is a mobile DDR SDRAM product released by Micron Technology. The product uses bidirectional data strobes, supports 1.8V voltage, and internally uses a dual-channel architecture to achieve two data accesses per cycle. The product has four internal banks that can perform concurrent operations. In addition, the product also supports programmable burst lengths, auto refresh and self refresh modes.
This Micron datasheet describes two mobile DDR SDRAM parts, the MT46H16M16LF (4 Meg × 16 × 4 banks) and the MT46H8M32LF (2 Meg × 32 × 4 banks). It lists electrical characteristics, functional features, and supported operating modes such as auto‑refresh, deep power‑down, and partial array self‑refresh.
Package options include 60‑ball and 90‑ball VFBGA formats, with timing options of 6 ns, 7.5 ns, and 10 ns cycle times. The parts operate from a 1.8 V supply and are qualified for commercial (0 °C to +70 °C) and industrial (‑40 °C to +85 °C) temperature ranges.
