71V67903 - Block Diagram


3.3V 512K x 18 Synchronous 3.3V I/O Flowthrough SRAM

The 71V67903 3.3V CMOS SRAM is organized as 512K x 18. The 71V67903 SRAM contains write, data, address and control registers. There are no registers in the data output path (flow-through architecture). The burst mode feature offers the highest level of performance to the system designer, as it can provide four cycles of data for a single address presented to the SRAM.


  • Fast access times 7.5ns up to 117MHz clock frequency
  • LBO input selects interleaved or linear burst mode
  • Self-timed write cycle with global write control (GW), byte write enable (BWE), and byte writes (BWx)
  • 3.3V core power supply
  • Power down controlled by ZZ input
  • 3.3V I/O supply (VDDQ)
  • Available in 100-pin TQFP, 119-pin BGA and 165 fpBGA packages
