7005S20PF

Memory IC Overview

The Renesas Electronics Corporation 7005S20PF is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kbit, organized as 8k words by 8 bits. The device features a parallel interface with a maximum access time of 20 ns. It operates on a single 5.0 V power supply, with a voltage range of 4.5 V to 5.5 V. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) and supports surface-mount installation. It functions within a commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• True dual-ported memory cells enable simultaneous independent reads from both ports without conflict.
• On-chip hardware logic supports semaphore signaling for port arbitration and master/slave configurations.
• Integrated interrupt flag functionality allows efficient status monitoring between connected processors.
• Automatic power-down mode reduces standby current when chip enable signals are inactive.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Real-time control systems requiring low-latency memory access
• Master/slave processor architectures for shared data exchange
• Industrial automation controllers needing reliable volatile storage

Memory IC Procurement Notes

Verify the specific suffix PF against official Renesas documentation to confirm package type and lead finish. Confirm RoHS compliance status as older variants may differ. Check moisture sensitivity level requirements for surface-mount assembly processes. Ensure the source document matches the exact part number to avoid pinout mismatches with similar packages.

Memory IC Selection Notes

Select this component when true dual-port capability is required for concurrent bus access. The 20 ns speed suits applications needing moderate latency without complex synchronization. Verify that the 64-pin TQFP footprint fits the board layout constraints. Consider the 5V TTL compatibility if interfacing with legacy digital logic circuits.
