HY57V283220(L)T(P)/ HY5V22(L)F(P)
4 Banks x 1M x 32Bit Synchronous DRAM
DESCRIPTION
The Hynix HY57V283220(L)T(P) / HY5V22(L)F(P) is a 134,217,728-bit CMOS Synchronous DRAM, ideally suited for the
memory applications which require wide data I/O and high bandwidth. HY57V283220(L)T(P) / HY5V22(L)F(P) is orga-
nized as 4banks of 1,048,576x32.
HY57V283220(L)T(P) / HY5V22(L)F(P) 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.)
