IS61QDPB24M18C-300M3I-TR 特徵

  • 2Mx36 and 4Mx18 configuration available.
  • On-chip Delay-Locked Loop (DLL) for wide data valid window.
  • Separate independent read and write ports with concurrent read and write operations.
  • Max. 450 MHz clock for high bandwidth
  • Synchronous pipeline read with EARLY write operation.
  • Double Data Rate (DDR) interface for read and
  • write input ports. 2.5 Cycle read latency. Fixed 2-bit burst for read and write operations. Two input clocks (K and K#) for address and control registering at rising edges only. Two echo clocks (CQ and CQ#) that are delivered simultaneously with data.
  • Data valid pin (QVLD).
  • HSTL input and output interface.
  • Full data coherency.
  • Boundary scan using limited set of JTAG 1149.1 functions.
  • Byte Write capability.
  • Fine ball grid array (FBGA) package option: 13mmx15mm and 15mmx17mm body size 165-ball (11 x 15) array
  • Programmable impedance output drivers via 5x user-supplied precision resistor.
  • ODT (On Die Termination) feature is supported optionally on data input, K/K#, and BWx#.

概觀

The IS61QDPB22M36C/C1/C2 and IS61QDPB24M18C/C1/ -C2 are 72Mb synchronous, high-performance CMOS static random access memory (SRAM) devices. These SRAMs have separate I/Os, eliminating the need for high-speed bus turnaround. The rising edge of K clock initiates the read/write operation, and all internal operations are self-timed. Refer to the description of the basic operations of these.
