71V3579S75PFGI

Overview

The 71V3579S75PFGI is a 4.5 Mbit (256K x 18) synchronous static random access memory manufactured by Renesas Electronics Corporation. It operates with a 3.3 V core supply and supports 3.3 V I/O levels. The device features a parallel interface with a maximum clock frequency of 117 MHz and an access time of 7.5 ns. It is housed in a 100-pin TQFP package suitable for surface mount installation.

Feature Summary

• Supports burst mode operations providing four cycles of data for a single address to enhance system performance.
• Includes self-timed write cycles controlled by global write control, byte write enable, and individual byte writes.

Applications

• High-performance embedded systems requiring fast data retrieval
• Network infrastructure equipment utilizing parallel SRAM interfaces
• Industrial control applications needing reliable volatile memory storage

Procurement Notes

Verify the specific suffix PFGI against official Renesas documentation to confirm pinout compatibility and RoHS status. Ensure the selected variant matches the required 100-pin TQFP package dimensions. Confirm that the 3.3 V operating voltage aligns with the target system power rails before finalizing procurement orders.

Selection Notes

Select this component when a 256K x 18 organization is required for synchronous parallel memory applications. The 7.5 ns access time suits designs demanding high-speed data processing. Consider the 100-pin TQFP footprint for PCB layout constraints. Verify thermal requirements for the specified operating temperature range during the design phase.

Part Context

This part belongs to the 71V3579 series of 3.3 V CMOS SRAMs. The series offers various access times and packaging options to accommodate different speed and form factor requirements. The 71V3579S75PFGI specifically targets applications needing 7.5 ns performance in a standard surface-mount package.

Replacement Considerations

Direct substitutes include variants within the same family such as 71V3579S65PFG or 71V3579S85PFG, which share identical pinouts but offer different access speeds. Cross-manufacturer equivalents like ISSI IS61LF25618A require verification of electrical characteristics and timing parameters.
