The R1QDA4436RBG is a 4, 194, 304-word by 36-bit and the R1QDA4418RBG is a 8, 388, 608-word by 18-bit synchronous quad data rate static RAM fabricated with advanced CMOS technology using full CMOS six-transistor memory cell. It integrates unique synchronous peripheral circuitry and a burst counter. All input registers are controlled by an input clock pair (K and /K) and are latched on the positive edge of K and /K. These products are suitable for applications which require synchronous operation, High-Speed, low voltage, high density and wide bit configuration. These products are packaged in 165-pin plastic FBGA package.

Features

  • Power Supply 1.8 V for core (VDD), 1.4 V to VDD for I/O (VDDQ)
  • Clock Fast clock cycle time for high bandwidth Two input clocks (K and /K) for precise DDR timing at clock rising edges only Two output echo clocks (CQ and /CQ) simplify data capture in high-speed systems Clock-stop capability with μs restart
  • I/O Separate independent read and write data ports with concurrent transactions 100% bus utilization DDR read and write operation HSTL I/O User programmable output impedance PLL circuitry for wide output data valid window and future frequency scaling Data valid pin (QVLD) to indicate valid data on the output
  • Function Four-tick burst for reduced address frequency Internally self-timed write control Simple control logic for easy depth expansion JTAG 1149.1 compatible test access port
  • Package 165 FBGA package (15 x 17 x 1.4 mm)
