Description

The µPD44165082 is a 2,097,152-word by 8-bit, the µPD44165182 is a 1,048,576-word by 18-bit and the µPD44165362 is a 524,288-word by 36-bit synchronous quad data rate static RAM fabricated with advanced CMOS technology using full CMOS six-transistor memory cell.

Key Features

  • 1.8 ± 0.1 V power supply and HSTL I/O
  • DLL circuitry for wide output data valid window and future frequency scaling
  • Separate independent read and write data ports with concurrent transactions
  • 100% bus utilization DDR READ and WRITE operation
  • Two-tick burst for low DDR transaction size
  • Two input clocks (K and /K) for precise DDR timing at clock rising edges only
  • Two output clocks (C and /C) for precise flight time and clock skew matching-clock and data delivered together to receiving device
  • Internally self-timed write control
  • Clock-stop capability with µs restart
  • User programmable impedance output
