EM428M1644RTA - Double DATA RATE SDRAM

Description

The EM428M1644RTA is high speed Synchronous graphic RAM fabricated with ultra high performance CMOS process containing 134,217,728 bits which organized as 2Meg words x 4 banks by 16 bits.

The 128Mb DDR SDRAM uses a double data rate architecture to accomplish high-speed operation.

Features

  • Internal Double-Date-Rate architecture with 2 Accesses per clock cycle.
  • VDD/VDDQ= 2.5V ±0.2V for (-75 and -6).
  • VDD/VDDQ= 2.6V ±0.1V for (-5 ).
  • 2.5V SSTL-2 compatible I/O.
  • Burst Length (B/L) of 2, 4, 8.
  • 2,2.5,3 Clock read latency.
  • Bi-directional,intermittent data strobe(DQS).
  • All inputs except data and DM are sampled at the positive edge of the system clock.
  • Data Mask (DM) for write data.
  • Sequential & Int.
