HY5DS283222BF(P)
DESCRIPTION
The Hynix HY5DS283222 is a 134,217,728-bit CMOS Double Data Rate(DDR) Synchronous DRAM, ideally suited for the
point-to-point applications which requires high bandwidth.
The Hynix 4Mx32 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.

ORDERING INFORMATION
Note) Hynix supports Lead free parts for each speed grade with same specification, except Lead free materials.
We'll add "P" character after "F" for lead free product.
For example, the part number of 300Mhz Lead free product is HY5DS283222BFP-33.
