7005S25PFG8

Overview

The Renesas Electronics Corporation 7005S25PFG8 is an asynchronous dual-port static random-access memory (SRAM) with a density of 64 kbit, organized as 8k x 8. It features a 25 ns access time and operates on a single 5.0 V TTL-compatible power supply within the 4.5 V to 5.5 V range. The device supports simultaneous independent reads from either port and includes hardware semaphore signaling for master/slave arbitration. It is housed in a 64-pin Thin Quad Flat Package (TQFP) with a 14.0 mm x 14.0 mm footprint and 0.8 mm pitch, rated for commercial temperatures from 0°C to +70°C.

Feature Summary

• True dual-ported architecture enabling simultaneous independent read access to shared memory locations by both ports.
• Integrated hardware support for semaphore signaling and interrupt flags to facilitate automatic port arbitration between master and slave modes.
• Asynchronous operation allowing flexible interface timing without external clock synchronization requirements.
• Automatic power-down functionality controlled by chip enable inputs to minimize standby power consumption.

Applications

• High-speed data buffering in telecommunications equipment requiring low-latency parallel interfaces.
• Master/slave processor systems utilizing hardware semaphore logic for efficient bus arbitration.
• Industrial control units operating within standard commercial temperature ranges.
• Embedded systems requiring non-volatile-like reliability with fast random access capabilities.

Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm RoHS compliance status and lead-free specifications against current datasheet revisions. Ensure proper handling procedures are followed due to moisture sensitivity level 3 classification. Validate package dimensions and pinout compatibility during integration planning. Review end-of-life notices and obsolescence warnings prior to final procurement decisions.

Selection Notes

Select this component when simultaneous bidirectional data access is required without complex software locking mechanisms. The 25 ns speed suits moderate-frequency asynchronous applications. Verify that the 64-TQFP package fits the available PCB real estate. Consider the 0°C to +70°C operating range suitability for the target environment. Evaluate alternative speeds if higher throughput is necessary for the specific system design.
