71V321LA45PF

Overview

The 71V321LA45PF is a high-performance static RAM (SRAM) device manufactured by Renesas Electronics Corporation. It features a capacity of 2 Megabits organized as 256K words by 8 bits. The component operates with a single 3.3V power supply and supports asynchronous access speeds of 45 nanoseconds. Key electrical characteristics include low standby current consumption and fast output enable times. The device utilizes CMOS technology to ensure reliable data retention and efficient power management for embedded applications requiring rapid memory access.

Feature Summary

• Asynchronous operation with fast access times
• Single voltage supply capability
• Low power consumption design

Applications

• Embedded systems requiring non-volatile-like speed
• Industrial control equipment memory buffers
• Telecommunications signal processing units

Procurement Notes

Verify the exact suffix PF against the manufacturer's latest datasheet to confirm package type and temperature range specifications. Ensure compatibility with system voltage levels before integration. Cross-reference part numbers with official Renesas distributors to avoid counterfeit components. Confirm lead times and availability directly with authorized suppliers as market conditions fluctuate.

Selection Notes

Select this component when asynchronous SRAM performance is required with specific timing constraints of 45ns. Consider the 256Kx8 organization for memory mapping requirements. Evaluate power budget constraints given the single 3.3V operation. Compare pinout compatibility with existing PCB layouts if replacing legacy parts.

Part Context

This part belongs to the 71V321L series of SRAMs, designed for general-purpose memory applications. The series offers various speed grades and package options to suit different system requirements. Renesas positions these devices in the embedded memory segment, focusing on reliability and ease of integration for industrial and commercial electronics.

Replacement Considerations

Check for direct pin-to-pin replacements within the same family or from other manufacturers offering equivalent 256Kx8 asynchronous SRAMs. Verify that substitute parts match the 45ns speed grade and 3.3V operating voltage. Ensure package dimensions are compatible with existing footprints.
