DESCRIPTION
The Hynix HY57V281620HC(L/S)T is a 134,217,728bit CMOS Synchronous DRAM, ideally suited for the Mobile applications which
require low power consumption and extended temperature range. HY57V281620HC(L/S)T is organized as 4banks of 2,097,152x16
HY57V281620HC(L/S)T is offering fully synchronous o peration referenced to a positive edge of the clock. All inputs and outputs are
synchronized with the risi ng edge of the clock input. The data paths are internally pipelined to achieve very h igh bandwidth. All input
and output voltage levels are compatible with LVTTL.
Programmable options incl ude the length o f pipeline (Rea d latency of 2 or 3), the n umber of consecutive read or write cycle s initiated
by a single control command (Burst length of 1,2,4,8, o r full page), and the burst cou nt sequence(sequ ential or interleave). A burst of
read or write cycles in progress can be terminated by a burst terminate command or can be interrupted and replaced by a new burst
read or write command on any cycle. (This pipelined design is not restricted by a `2N` rule.)
