71421LA25PFGI8

Overview

The 71421LA25PFGI8 is a dual-port static random-access memory integrated circuit manufactured by Renesas Electronics. It provides a storage capacity of 16 kbit, organized as 2K x 8 bits. The device features asynchronous parallel interface with a maximum access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 64-TQFP package.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface for flexible system integration
• Volatile SRAM technology maintaining data during power supply

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded controllers
• Data logging applications requiring rapid write cycles

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and moisture sensitivity level (MSL) ratings prior to PCB assembly. Ensure proper handling procedures are followed to prevent electrostatic discharge damage during storage and installation processes.

Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Compare against single-port alternatives if only one port is needed. Verify that the 4.5 V to 5.5 V operating voltage aligns with the target system power rails. Consider the 64-TQFP package dimensions for board layout constraints.

Part Context

This part belongs to the 71421LA series of dual-port SRAMs from Renesas. It shares architectural similarities with other members like the 71321LA and 71421SA series, differing primarily in speed grades and specific pin configurations. The LA suffix typically denotes commercial temperature range variants within the product family.
