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.)

PIN DESCRIPTION
PIN PIN NAME DESCRIPTION
CLK Clock The system clock input. All other inputs are registered to the SDRAM on the
rising edge of CLK
CKE Clock Enable Controls internal clock signal and when deactivated, the SDRAM will be one
of the states among power down, suspend or self refresh
CS Chip Select Enables or disables all inputs except CLK, CKE, UDQM and LDQM
BA0, BA1 Bank Address Selects bank to be activated during RAS activity
Selects bank to be read/written during CAS activity
A0 ~ A11 Address Row Address : RA0 ~ RA11, Column Address : CA0 ~ CA8
Auto-precharge flag : A10
RAS, CAS, WE Row Address Strobe, Col-
umn Address Strobe, Write
