概要

The 71V65703 3.3V CMOS SRAM, organized as 256K x 36, is designed to eliminate dead bus cycles when turning the bus around between reads and writes or writes and reads. Thus it has been given the name ZBT™, or Zero Bus Turnaround. The 71V65703 contains address, data-in, and control signal registers. The outputs are flow-through (no output data register). In the burst mode, it can provide four cycles of data for a single address presented to the SRAM.

71V65703 - Block Diagram
  • High-performance system speed - 100MHz (7.5ns Clock-to-Data access)
  • ZBT feature - No dead cycles between write and read cycles
  • Internally synchronized output buffer enable eliminates the need to control OE
  • Single R/W (Read/Write) control pin
  • 4-word burst capability (interleaved or linear)
  • Individual byte write (BW1 - BW4) control (May tie active)
  • Three chip enables for simple depth expansion
  • 3.3V power supply (±5%)
  • 3.3V (±5%) I/O supply (VDDQ)
  • Power down controlled by ZZ input
  • Available in 100-pin TQFP, 119-pin BGA, and 165 fpBGA packages

    Parametric Table tips

    Tips for Using This Parametric Table:

    • Hide Filters button in header: Collapse or expands filters
    • Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
    • Reset button in header: Reset all filters to the page default
    • Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
    • Export button in header: Export the filtered results of the table to an Excel document
    • Filter parts search bar in header: Type to filter table results by part number
    • Hide column button in column headers: Select to hide columns in table
    • AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
    • Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
    • Document icon next to product name in row: View the featured document for this product
    • Chip icon next to the right of the document icon in row: View the block diagram for this product
    • Cart icon to the right of the chip icon: Indicates that samples are available for this product
