HY57V653220B
4 Banks x 512K x 32Bit Synchronous DRAM
DESCRIPTION
The Hynix HY57V653220B is a 67,108,864-bit CMOS Synchronous DRAM, ideally suited for the memory applications
which require wide data I/O and high bandwidth. HY57V653220B is organized as 4banks of 524,288x32.
HY57V653220B 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.)
FEATURES
• JEDEC standard 3.3V power supply
• Auto refresh and self refresh
• All device pins are compatible with LVTTL interface • 4096 refresh cycles / 64ms
• JEDEC standard 400mil 86pin TSOP-II with 0.5mm of • Programmable Burst Length and Burst Type
pin pitch
- 1, 2, 4, 8 or full page for Sequential Burst
• All inputs and outputs referenced to positive edge of
system clock
- 1, 2, 4 or 8 for Interleave Burst
• Data mask function by DQM0,1,2 and 3
• Programmable CAS Latency ; 2, 3 Clocks
• Internal four banks operation
• Burst Read Single Write operation
