HY57V28820HC(L)T-I
4Banks x 4M x 8bits Synchronous DRAM
DESCRIPTION
The Hynix HY57V28820HC(L)T is a 134,217,728bit CMOS Synchronous DRAM, ideally suited for the Mobile applica-
tions which require low power consumption and extended temperature range. f HY57V28820HC(L)T is organized as
4banks of 4,194,304x8.
HY57V28820HC(L)T is offering fully synchronous operation referenced to a positive edge of the clock. All inputs and
outputs are synchronized with the rising edge of the clock input. The data paths are internally pipelined to achieve very
high bandwidth. All input and output voltage levels are compatible with LVTTL.
Programmable options include the length of pipeline (Read latency of 2 or 3), the number of consecutive read or write
cycles initiated by a single control command (Burst length of 1,2,4,8 or full page), and the burst count
sequence(sequential 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.)
