IS66WVH16M8DBLL Features

  • 3.0V I/O, 11 bus signals
    • Single ended clock (CK)
  • 1.8V I/O, 12 bus signals
    • Differential clock (CK, CK#)
  • Chip Select (CS#)
  • 8-bit data bus (DQ[7:0])
  • Read-Write Data Strobe (RWDS)
    • Bidirectional Data Strobe / Mask
    • Output at the start of all transactions to indicate refresh latency
    • Output during read transactions as Read Data Strobe
    • Input during write transactions as Write Data Mask
  • RWDS DCARS Timing
    • During read transactions RWDS is offset by a second clock, phase shifted from CK
    • The Phase Shifted Clock is used to move the RWDS transition edge within the read data eye Performance Summary High Performance Up to 400MB/s
  • Double-Data Rate (DDR) - two data transfers per clock
  • 200-MHz clock rate (400 MB/s) at 1.8V VCC 166-MHz clock rate (332 MB/s) at 1.8V VCC
  • 166-MHz clock rate (332 MB/s) at 3.0V VCC
  • Sequential burst transactions
  • Configurable Burst Characteristics ,105°C ,125°C ,105°C/125°C
    • Wrapped burst lengths:
    • 16 bytes (8 clocks)
    • 32 bytes (16 clocks)
    • 64 bytes (32 clocks)
    • 128 bytes (64 clocks)
    • Linear burst
    • Hybrid option - one wrapped burst followed by linear burst
    • Wrapped or linear burst type selected in each transaction
    • Configurable output drive strength
  • Temperature Grade
    • Industrial: -40°C to +85°C Auto (A2) Grade: -40°C to +105°C Auto (A3) Grade: -40°C to +125°C

Overview

The IS66/67WVH16M8DALL/BLL are integrated memory device containing 128Mbit Pseudo Static Random Access Memory using a self-refresh DRAM array organized as 16M words by 8 bits. The device supports a HyperBus interface, Very Low Signal Count (Address, Command and data through 8 DQ pins), Hidden Refresh Operation, and Automotive Temperature Operation, designed specially for Mobile and Automotive applications.
