HY5V56D(L/S)FP Series
4 Banks x 4M x 16bits Synchronous DRAM
DESCRIPTION
The HY5V56D(L/S)FP is a 268,435,456bit CMOS Synchronous DRAM, ideally suited for the Mobile applications which
require low power consumption and industrial temperature range. HY5V56D(L/S)FP is organized as 4banks of
4,194,304x16
HY5V56D(L/S)FP is offering fully synchronous operation referenced to a positive edge of the clock. All inputs and out-
puts 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.)

INPUT
DESCRIPTION
Clock : The system clock input. All other inputs are registered to the
SDRAM on the rising edge of CLK
Clock Enable : Controls internal clock signal and when deactivated, the
SDRAM will be one of the states among power down, suspend or self
refresh
Chip Select : Enables or disables all inputs except CLK, CKE, UDQM and
LDQM
Bank Address : Selects bank to be activated during RAS activity
Selects bank to be read/written during CAS activity
