71V3576YS133PFG

Overview

The IDT71V3576YS133PFG is a high-speed synchronous SDRAM SRAM manufactured by Renesas Electronics Corporation. It features a memory organization of 128K x 36, providing a total capacity of 4.5Mb. The device supports clock frequencies up to 133 MHz with an access time of 4.2 ns. It operates on a 3.3V core power supply and accepts 3.3V I/O signals. The component is housed in a 100-pin plastic thin quad flatpack (TQFP) package, specifically identified as 100-TQFP(14x14).

Feature Summary

• Supports high system speed with pipelined outputs for improved data throughput.
• Includes a burst counter and single cycle deselect capability for flexible operation.
• Features self-timed write cycles controlled by global write control and byte write enables.

Applications

• High-performance computing systems requiring fast cache memory.
• Network infrastructure equipment needing low-latency data buffering.
• Industrial automation controllers utilizing synchronous memory interfaces.

Procurement Notes

Verify the manufacturer designation, as documentation lists both IDT and Renesas Electronics Corporation for this part number. Confirm the specific suffix 'YS' aligns with the required RoHS compliance status and packaging type. Check for product discontinuance notices or last-buy deadlines associated with the 71V3576 family before finalizing procurement plans.

Selection Notes

Select this component when a 128K x 36 configuration is required for parallel synchronous applications. Ensure the design accommodates the 100-pin TQFP footprint and 3.3V logic levels. Consider alternative speeds if higher frequency performance beyond 133 MHz is necessary for the target application.
