71V30L35TF8

Overview

The Renesas Electronics Corporation 71V30L35TF8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It features an 8-kbit storage capacity organized as 1K x 8 bits. The component supports parallel interface access with a maximum access time of 35 ns. It operates on a single 3.3V power supply within a voltage range of 3.0V to 3.6V. The device is housed in a 64-pin Thin Quad Flat Package (TQFP) with a 10mm x 10mm footprint and 0.5mm pitch. It is designed for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• True dual-ported architecture enabling simultaneous independent access to the same memory location by two separate ports.
• On-chip port arbitration logic manages bus conflicts during concurrent read/write operations.
• Asynchronous operation allows flexible timing control without requiring a system clock signal.

Applications

• Real-time data buffering between independent processing units
• High-speed cache memory in embedded systems
• Data logging applications requiring non-volatile backup support

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations such as TFGI or TFGI8 indicate specific RoHS compliance levels and reel packaging options. Confirm moisture sensitivity level (MSL 3) handling requirements before assembly. Ensure the selected variant matches the required operating temperature grade and package dimensions for your PCB design.

Selection Notes

Select this component when simultaneous bidirectional data transfer is required without external arbitration hardware. The 35ns access speed suits moderate-frequency asynchronous interfaces. Consider the 64-pin TQFP package constraints for board space. Verify that the 3.3V logic levels are compatible with the connected microcontrollers or processors.

Part Context

This part belongs to the 71V30 series of dual-port SRAMs from Renesas. The series offers various access speeds and package options. The 'L' designation typically indicates low-power characteristics and battery backup capability. The '35' denotes the 35 nanosecond access time specification.

Replacement Considerations

Direct substitutes include IDT71V30L35TFGI8 and other variants within the 71V30L35 family. Verify pin compatibility and electrical specifications before substitution. Note that some older variants may be obsolete.
