The EM488M1644VTG is Synchronous Dynamic Random Access Memory (SDRAM) organized as 2Meg words x 4 banks by 16 bits. All inputs and outputs are synchronized with the positive edge of the clock. The 128Mb 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. EM488M1644VTG is available in TSOPII 54Pin package.
