256Mb: x16 Mobile SDRAM is a mobile storage device produced by Micron. Its features include programmable burst length, auto refresh mode, self refresh mode, 64ms, 8,192-cycle refresh, LVTTL-compatible input and output, low voltage power supply, deep power down, partial array self refresh power-saving mode, industrial operating temperature (-40oC to +85oC).
The MT48V16M16LFFG is a 256 Mb (16 M × 16) mobile SDRAM offered in a 54‑ball FBGA package. It operates at either 2.5 V or 1.8 V and is rated for industrial temperatures from –40 °C to +85 °C. The device features a fully synchronous interface, internal pipelined operation, and programmable burst lengths.
The datasheet details the functional block diagram, pin assignments, mode‑register settings, timing parameters, power‑down modes, and extended features such as Temperature‑Compensated Self‑Refresh (TCSR) and Partial Array Self‑Refresh (PASR). It also provides absolute maximum ratings and electrical characteristics for design engineers.
