Description

The H5TC4G83CFR-xxA(I,L,J),H5TQC4G63CFR-xxA(I,L,J) are a 4Gb low power Double Data Rate III

(DDR3L) Synchronous DRAM, ideally suited for the main memory applications which requires large

memory density, high bandwidth and low power operation at 1.35V. SK Hynix DDR3L SDRAM provides

backward compatibility with the 1.5V DDR3 based environment without any changes. SK Hynix 4Gb DDR3L

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 clock (falling edges of the clock),

data, data strobes and write data masks inputs are sampled on both rising and falling edges of it. The data

paths are internally pipelined and 8-bit prefetched to achieve very high bandwidth.
