71321LA25J

Memory IC Overview

The Renesas Electronics Corporation 71321LA25J is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 52-pin Plastic Leadless Chip Carrier (PLCC) package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface for flexible system integration
• CMOS technology construction for low power consumption

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications

Memory IC Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Review the official product discontinuance notice for lifecycle implications. Ensure packaging specifications match assembly requirements. Validate technical parameters against current design specifications before finalizing orders.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data handling. The 25-nanosecond access speed suits moderate-to-high frequency applications. Verify that the 52-PLCC package fits the printed circuit board layout. Ensure the operating temperature range meets environmental conditions. Compare against single-port alternatives if only one port is needed.
