DESCRIPTIONThe Hynix HY57V281620HC(L/S)T is a 134,217,728bit CMOS Synchronous DRAM, ideally suited for the main memory applicationswhich require large memory density and high bandwidth. 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.

FEATURES • Single 3.3±0.3V power supply • All device pins are compatible with LVTTL interface • JEDEC standard 400mil 54pin TSOP-II with 0.8mm

of pin pitch • All inputs and outputs referenced to positive edge of

system clock • Data mask function by UDQM or LDQM • Internal four banks operation • Auto refresh and self refresh • 4096 refresh cycles / 64ms • Programmable Burst Length and Burst Type

- 1, 2, 4, 8 or Full page for Sequential Burst- 1, 2, 4 or 8 for Interleave Burst
