Description
The H5TC1G43BFR-xxA, H5TC1G83BFR-xxA and H5TC1G63BFR-xxA are a 1Gb 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. Hynix DDR3L SDRAM provides back-
ward compatibility with the 1.5V DDR3 based environment without any changes. (Please refer to the SPD
information for details.)
Hynix 1Gb 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.
