Ordering Information

Description

The EM488M3244VBD is Synchronous Dynamic

Random Access Memory (SDRAM) organized as

2Meg words x 4 banks by 32 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 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.

Available packages: TFBGA-90B(13mmx8mm).
