71V321S35J

Overview

The Renesas Electronics 71V321S35J is a dual-port static random-access memory (SRAM) device. It features a storage capacity of 16 kbit, organized as 2K x 8 bits. The component supports asynchronous parallel interface operation with a maximum access time of 35 ns. It operates on a single 3.0 V to 3.6 V power supply and is housed in a 52-lead PLCC package. The device is designed for surface mount installation and functions within an operating temperature range of 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling simultaneous independent access from two separate ports
• Asynchronous operation allowing flexible timing control for both read and write cycles
• On-chip port arbitration logic for managing concurrent memory access requests

Applications

• High-speed data buffering in communication systems
• Real-time processing applications requiring low-latency memory access
• Industrial equipment control systems

Procurement Notes

Verify the specific suffix 'J' against official Renesas documentation to confirm package type and compliance status. Check current lifecycle status as this series may be discontinued or subject to change. Confirm moisture sensitivity level requirements for your assembly process. Ensure voltage and temperature ratings match your system design constraints before procurement.

Selection Notes

Select this component when dual-port functionality is required for shared memory resources. Compare access times and power consumption against other SRAM families. Verify pin compatibility if replacing legacy parts. Consider industrial temperature ranges if operating conditions exceed commercial limits. Evaluate package availability for your manufacturing setup.
