HY57V641620HG Datasheet 4 Banks X 1m X 16bit Synchronous Dram

Manufacturer: SK Hynix

Overview: HY57V641620HG 4 Banks x 1M x 16Bit Synchronous DRAM D E S C R IP T IO N The Hynix HY57V641620HG is a 67,108,864-bit CMOS Synchronous DRAM, ideally suited for the main memory applications which require large memory density and high bandwidth. HY57V641620HG is organized as 4banks of 1,048,576x16. HY57V641620HG 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 patible 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 mand (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 mand or can be interrupted and replaced by a new burst read or write mand on any cycle. (This pipelined design is not restricted by a `2N` rule.

Key Features

  • Single 3.3± 0 . 3 V power supply Note).
  • 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 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 - 1, 2, 4 or 8 for Interleave Burst.
  • Programmable.
