71V30S35TF8

Overview

The 71V30S35TF8 is an asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It provides a storage capacity of 8 kilobits, organized as 1K words by 8 bits. The device features parallel interface access with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 3.0 volts to 3.6 volts and is housed in a 64-lead Thin Quad Flat Package (TQFP) measuring 10x10 millimeters. The component supports surface-mount installation and functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Supports simultaneous independent read and write operations through two separate ports
• Provides high-speed asynchronous data access for efficient system integration
• Operates on standard 3.3-volt logic levels for compatibility with common digital systems

Applications

• Data buffering in communication interfaces
• Cache memory implementation in embedded processors
• FIFO buffer applications in signal processing chains

Procurement Notes

Verify the exact suffix configuration against the manufacturer datasheet to ensure correct package and temperature grade. Confirm RoHS compliance status as older batches may differ. Check for official obsolescence notices or lifecycle changes before finalizing procurement plans. Ensure ESD handling protocols are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this component when dual-port functionality is required for concurrent host and peripheral access. Compare access times against system clock requirements to ensure 35 ns meets timing constraints. Verify that the 64-TQFP footprint aligns with existing PCB layout specifications. Consider thermal dissipation capabilities within the specified operating temperature range.

Part Context

This part belongs to the IDT/Renesas 71V30 series of high-speed dual-port SRAMs. The series offers various speed grades and packaging options to suit different performance needs. The 71V30S variant specifically denotes the standard commercial temperature range version. It serves as a legacy component in designs requiring reliable non-volatile-free temporary storage.

Replacement Considerations

Official substitutes include the 71V30L25TFG8 for faster 25 ns access speeds. The 71V30S35TF8 itself is listed as obsolete; verify current availability or approved alternates from Renesas.
