1HY5DU281622ETP
DESCRIPTION
The Hynix HY5DU281622ETP is a 134,217,728-bit CMOS Double Data Rate(DDR) Synchronous DRAM, ideally suited for
the point-to-point applications which require high densities and high bandwidth.
The Hynix 8Mx16 DDR SDRAMs offer fully synchronous operations referenced to both rising and falling edges of the
clock. While all addresses and control inputs are latched on the rising edges of the CK (falling edges of the /CK), Data,
Data strobes and Write data masks inputs are sampled on both rising and falling edges of it. The data paths are inter-
nally pipelined and 2-bit prefetched to achieve very high bandwidth. All input and output voltage levels are compatible
with SSTL_2.
