IS49NLC18320A-18WBLI-TR 特徵

  • 533MHz DDR operation (1.067 Gb/s/pin data rate) 38.4Gb/s peak bandwidth (x36 at 533 MHz clock frequency)
  • Differential input clocks (CK, CK#)
  • Differential input data clocks (DKx, DKx#)
  • On-die DLL generates CK edge-aligned data and
  • Reduced cycle time (15ns at 533MHz)
  • 32ms refresh (16K refresh for each bank; 128K refresh command must be issued in total each 32ms) 8 internal banks
  • Non-multiplexed addresses (address multiplexing option available)
  • SRAM-type interface
  • Programmable READ latency (RL), row cycle time, and burst sequence length
  • Balanced READ and WRITE latencies in order to optimize data bus utilization
  • Data mask signals (DM) to mask signal of WRITE data; DM is sampled on both edges of DK. OPTIONS
  • Package:  144-ball WBGA (lead-free) output data clock signals
  • Data valid signal (QVLD)
  • HSTL I/O (1.5V or 1.8V nominal)
  • On-die termination (ODT) RTT
  • Operating temperature: 25-60Ω matched impedance outputs 2.5V VEXT, 1.8V VDD, 1.5V or 1.8V VDDQ I/O IEEE 1149.1 compliant JTAG boundary scan Commercial (TC = 0° to +95°C ) Industrial (TC = -40°C to +95°C; TA = -40°C to +85°C)
