71V3559S80PFG8

Overview

The 71V3559S80PFG8 is a synchronous single data rate (SDR) static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a parallel interface and a storage capacity of 4.5 megabits, organized as 256K words by 18 bits. The device supports an access time of 8 nanoseconds with a maximum clock frequency of 100 MHz. It operates on a single 3.3V power supply within a voltage range of 3.135V to 3.465V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm, designed for surface-mount installation.

Feature Summary

• Supports high-speed synchronous operation with a maximum clock frequency of 100 MHz and fast 8 ns access time.
• Features a wide 18-bit data bus width suitable for high-bandwidth applications requiring parallel data transfer.
• Includes self-timed write cycles controlled by global write control and byte write enable signals.

Applications

• High-performance processor secondary cache systems
• Network infrastructure equipment requiring fast data buffering
• Industrial automation controllers needing rapid memory access

Procurement Notes

Verify the specific suffix PFG8 against official Renesas documentation to confirm package dimensions and pinout compatibility. Confirm RoHS compliance status as some variants may not meet current environmental standards. Check for end-of-life notices or production change notifications that may affect long-term availability and supply chain stability.

Selection Notes

Select this component when a system requires a wide 18-bit data path and synchronous timing constraints. Ensure the design accommodates the 100-pin TQFP footprint and 3.3V logic levels. Compare against other 71V3559 variants if different access speeds or package types are required for space or performance optimization.

Part Context

This part belongs to the 71V3559 family of 3.3V CMOS SRAMs. The family offers various access times and package options to suit different system requirements. The S80 variant specifically targets applications needing 8 ns speed, while the PFG8 suffix denotes the 100-pin TQFP packaging configuration used in this specific model.

Replacement Considerations

Check for direct substitutes within the 71V3559 series such as the 71V3559S85PFG8 for slower speed requirements. Verify pin-to-pin compatibility with other 100-pin TQFP SRAMs from Renesas or IDT before substitution.
