HY5V52CF
4 Banks x 2M x 32Bit Synchronous DRAM
DESCRIPTION
Preliminary
The Hynix HY5V52CF is a 268,435,456bit CMOS Synchronous DRAM, ideally suited for the memory applications
which require wide data I/O and high bandwidth. HY5V52CF is organized as 4banks of 2,097,152x32.
HY5V52CF 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 band-
width. 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
The system clock input. All other inputs are registered to the SDRAM on the rising edge
of CLK.
Controls internal clock signal and when deactivated, the SDRAM will be one of the states
among power down, suspend or self refresh
Enables or disables all inputs except CLK, CKE and DQM
Selects bank to be activated during RAS activity
Selects bank to be read/written during CAS activity
Row Address : RA0 ~ RA11, Column Address : CA0 ~ CA8
Auto-precharge flag : A10
RAS, CAS and WE define the operation
Refer function truth table for details
Controls output buffers in read mode and masks input data in write mode
Multiplexed data input / output pin
