71V30L25TFG

Memory IC Overview

The Renesas Electronics Corporation 71V30L25TFG 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 with parallel interface access. The component operates on a single 3.3V power supply and supports simultaneous independent reads or writes from two separate ports. Key electrical parameters include a maximum access time of 25 ns, a minimum operating voltage of 3 V, and a maximum operating voltage of 3.6 V. The device is housed in a 64-pin TQFP surface-mount package.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous access to the same memory location from both ports.
• On-chip port arbitration logic facilitates interrupt flags for efficient port-to-port communication.
• Fully asynchronous operation allows independent control, address, and I/O pins for each port.
• Automatic power-down feature controlled by chip enable signals reduces standby power consumption.

Memory IC Applications

• Stand-alone 8-bit dual-port SRAM implementations
• Systems requiring battery backup with data retention capabilities
• Industrial equipment utilizing TTL-compatible logic levels

Memory IC Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct package type and temperature grade. Confirm moisture sensitivity level handling requirements prior to assembly. Cross-reference manufacturer part numbers with distributor listings to validate authenticity and current production status. Ensure compatibility with system voltage tolerances and interface standards before finalizing procurement orders.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data transfer is required without external arbitration hardware. The 25 ns access speed suits applications needing rapid response times. Verify that the 64-pin TQFP footprint matches the target PCB layout constraints. Consider the industrial temperature range availability if the deployment environment exceeds standard commercial limits.

Memory IC Part Context

This device belongs to the 71V30 series of dual-port RAMs manufactured by Renesas Electronics. The series provides scalable memory solutions with varying access speeds and temperature grades. The 71V30L25 variant specifically targets general-purpose applications requiring reliable, high-speed asynchronous memory operations within a compact surface-mount form factor.

Memory IC Replacement Considerations

Direct substitutes include the 71V30L25TFGI for industrial temperature ranges. Verify pinout compatibility and electrical specifications before swapping components. Alternative packages such as tray versions may require re-evaluation of manufacturing processes.
