Description
The EM48AM1684LBB is Synchronous Dynamic
Random Access Memory (SDRAM) organized as
2 x 4 banks x 2 Mbit by 16 bits. All inputs and
outputs are synchronized with the positive edge of
the clock.
The 256Mb SDRAM uses synchronized pipelined
architecture to achieve high speed data transfer
rates and is designed to operate at 1.8V low power
memory system. It also provides auto refresh with
power saving / down mode. All inputs and outputs
voltage levels are compatible with LVCMOS.
Available packages:TFBGA 54B 12mm x 8mm.
