Description
The EM481M1622VTA is Synchronous Dynamic Random Access Memory (SDRAM) organized as
512K x 2 banks x 16 bits. All inputs and outputs are synchronized with the positive edge of the clock.
The 16Mb SDRAM uses synchronized pipelined architecture to achieve high speed data transfer rates
and is designed to operate at 3.3V low power memory system. It also provides auto refresh with power
saving / down mode. All inputs and outputs voltage levels are compatible with LVTTL .
