71V3579S80PFG

Overview

The 71V3579S80PFG is a Synchronous Single Data Rate (SDR) Static Random Access Memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 4.5 Megabits, organized as 256K words by 18 bits. The device features a parallel interface and operates with a maximum clock frequency of 100 MHz, achieving an access time of 8 nanoseconds. It functions within a supply voltage range of 3.135V to 3.465V and supports an operating temperature range of 0°C to 70°C. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm.

Feature Summary

• Supports high-speed data transfer via a synchronous parallel interface architecture
• Provides non-volatile data retention capabilities typical of SRAM technology
• Designed for low power consumption operations in embedded environments

Applications

• Industrial control systems requiring fast memory access
• Telecommunications equipment signal processing
• Internet of Things (IoT) embedded applications

Procurement Notes

Verify the specific suffix 'PFG' corresponds to the 100-TQFP package variant when sourcing. Confirm RoHS compliance status as legacy IDT variants may differ. Ensure the supplier provides official Renesas documentation to validate the 100 MHz speed grade and 8 ns access time specifications against potential counterfeit or mislabeled components.

Selection Notes

Select this component when a 4.5Mb synchronous SRAM with an 18-bit data width is required. The 100 MHz clock speed suits applications needing moderate latency. Compare against the 71V3579S85PFG if slower speeds are acceptable for lower power, or consider the 71V3579S65PFG for faster performance needs, noting package differences between TQFP and LQFP options.

Part Context

This part belongs to the Renesas 71V3579 series of synchronous SRAMs, originally developed under the IDT brand before acquisition. The series offers various speed grades and package options. The 71V3579S80PFG specifically represents the 100 MHz speed bin in the standard TQFP form factor, serving as a bridge between older asynchronous memories and higher-performance synchronous solutions.

Replacement Considerations

The IDT71V3579S65PF is a discontinued direct substitute available from Renesas. Verify pin compatibility and electrical characteristics against the IS61LF25618A-7.5TQLI for similar functionality.
