71421SA20PF

Overview

The Renesas Electronics Corporation 71421SA20PF is a dual-port static random-access memory (SRAM) IC. It features a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device utilizes a parallel interface with an access time and write cycle time of 20 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) measuring 14x14 mm. The component is designed for commercial temperature ranges from 0°C to 70°C.

Feature Summary

• Supports simultaneous independent read and write operations at two distinct ports
• Provides asynchronous logic control for flexible system integration
• Delivers high-speed data transfer capabilities via parallel interface

Applications

• High-performance embedded systems requiring concurrent data access
• Industrial automation controllers needing fast local memory buffering
• Telecommunications equipment utilizing real-time signal processing

Procurement Notes

Verify the specific suffix PF against official Renesas documentation to confirm package type and tape-and-reel configuration. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for end-of-life notifications or discontinuance notices prior to finalizing procurement plans.

Selection Notes

Select this component when dual-port architecture is required for separate processor or bus connections. Ensure the 20ns speed meets system timing requirements. Verify that the 64-TQFP footprint matches the printed circuit board layout constraints and thermal management needs.
