71V321LA55PF

Overview

The Renesas 71V321LA55PF is a high-performance static RAM device featuring a 32K x 1 configuration with low power consumption. It operates at a maximum access time of 55 nanoseconds and supports a supply voltage range of 2.7 to 3.6 volts. The component utilizes a CMOS technology process, ensuring reliable data retention and fast read/write cycles. It is housed in a compact 48-pin TSOP II package, designed for space-constrained embedded applications requiring efficient memory solutions.

Feature Summary

• Low power operation suitable for battery-powered devices
• Fast access times for high-speed data processing
• Compact surface-mount packaging for dense circuit designs

Applications

• Embedded systems requiring non-volatile-like speed
• Portable electronic devices with limited power budgets
• Industrial control units needing reliable memory storage

Procurement Notes

Verify the specific suffix PF indicates the correct package type and temperature grade before ordering. Confirm compatibility with your system's voltage levels and timing requirements. Ensure the source provides genuine Renesas products to avoid counterfeit risks. Check for any recent lifecycle status updates regarding availability or obsolescence.

Selection Notes

Choose this part when low power consumption and moderate speed are critical. It fits applications where a 32K x 1 memory depth is sufficient. Consider the TSOP II package size against your PCB layout constraints. Compare against other SRAM options if higher density or faster speeds are needed.

Part Context

This component belongs to Renesas' 71V321L series of low-power SRAMs. It shares architectural similarities with other members of the family but differs in package and speed grades. The series is designed for general-purpose memory applications in consumer and industrial electronics.

Replacement Considerations

Check for direct pin-compatible alternatives from Renesas or other manufacturers. Verify that substitute parts meet the same electrical specifications and package dimensions. Ensure functional equivalence in terms of access time and power consumption.
