71421LA25PF

Overview

The Renesas Electronics Corporation 71421LA25PF is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 16 kilobits organized as 2K x 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 64-pin Thin Quad Flat Package (TQFP). The component is designed for industrial temperature ranges, functioning reliably between -40°C and +85°C.

Feature Summary

• Provides independent read/write access to two distinct ports simultaneously without bus contention
• Supports high-speed asynchronous data transfer via parallel interface architecture
• Ensures reliable operation across extended industrial temperature environments

Applications

• Real-time data buffering in industrial automation systems
• High-speed cache memory in embedded processing units
• Data logging applications requiring simultaneous port access

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations indicate differences in packaging or environmental ratings. Confirm RoHS compliance status and moisture sensitivity levels prior to integration. Ensure the selected variant matches the required operating temperature range and voltage specifications for the target application environment.

Selection Notes

Select this component when simultaneous independent access to shared memory is required. Compare access times and power consumption against alternative SRAM families. Verify pin compatibility and package dimensions for PCB layout constraints. Consider long-term availability and lifecycle status for production planning purposes.
