7005S25PF8

Overview

The Renesas Electronics Corporation 7005S25PF8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a density of 64 kilobits. It features an 8K x 8 organization and operates on a single 5.0 V power supply within a 4.5 V to 5.5 V range. The device provides a maximum access time of 25 ns and supports simultaneous independent reads from both ports. It is housed in a 64-pin Thin Quad Flat Package (TQFP) measuring 14.0 mm by 14.0 mm with a 0.8 mm pitch. The component functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• True dual-ported architecture enabling simultaneous independent read operations from both ports without conflict.
• Integrated hardware support for master/slave configurations, including semaphore signaling and port arbitration logic.
• Asynchronous operation allowing flexible timing control from either port independently.
• Automatic power-down feature controlled by chip enable signals to minimize standby power consumption.

Applications

• Stand-alone 64K-bit dual-port memory systems
• Master/Slave dual-port RAM combinations for 16-bit or wider data bus architectures
• Battery-backed systems requiring 2V data retention capabilities

Procurement Notes

Verify the specific suffix 'PF8' against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as historical records indicate non-compliance for this series. Validate lead-free availability and moisture sensitivity level requirements before procurement planning.

Selection Notes

Select this component when simultaneous independent access to shared memory locations is required. Ensure the design accommodates the 5V TTL-compatible I/O levels and the 0°C to 70°C operating temperature range. Verify that the 64-TQFP footprint matches the PCB layout constraints.

Part Context

This part belongs to the IDT 7005 family of dual-port SRAMs, originally developed by Integrated Device Technology and later acquired by Renesas Electronics. The family is designed for applications requiring high-speed data sharing between two processors or controllers without external arbitration overhead.
