Description

The H5TC2G43AFR-xxA, H5TC2G83AFR-xxA are a 2Gb low power Double Data Rate III (DDR3L) Synchro-

nous DRAM, ideally suited for the main memory applications which requires large memory density, high

bandwidth and low power operation at 1.35V. Hynix DDR3L SDRAM provides backward compatibility with

the 1.5V DDR3 based environment without any changes. (Please refer to the SPD information for details.)

Hynix 2Gb 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.
