HY5V26C(L/S)F-I Series
4 Banks x 2M x 16bits Synchronous DRAM
DESCRIPTION
The Hynix HY5V26C(L/S)F is a 134,217,728bit CMOS Synchronous DRAM, ideally suited for the Mobile applications which require
low power consumption and industrial temperature range. HY5V26C(L/S)F is organized as 4banks of 2,097,152x16
HY5V26C(L/S)F is offering fully synchronous operation referenced to a positive edge of the clock. All inputs and outputs are synchro-
nized 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.)

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 deacti-
vated, 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 activ-
ity
Selects bank to be read/written during CAS activity
Row Address : RA0 ~ RA11, Column Address : CA0 ~ CA8
Auto-precharge flag : A10
Command Inputs : RAS, CAS and WE define the operation
Refer function truth table for details
Data Mask:Controls output buffers in read mode and masks
input data in write mode
Data Input/Output:Multiplexed data input/output ball
