7005S15PF8

Overview

The Renesas Electronics Corporation 7005S15PF8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 64 kilobits organized as 8K words by 8 bits. The component features parallel interface access with a maximum access time of 15 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The device is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm and a pitch of 0.8 mm. It supports an industrial operating temperature range from 0°C to 70°C.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads and writes from two distinct ports without conflict.
• Integrated hardware semaphore signaling logic for automatic port arbitration and synchronization between master and slave operations.
• Asynchronous operation capability allowing flexible timing control from either port independently.
• Automatic power-down feature controlled by chip enable inputs to minimize standby power consumption.

Applications

• Stand-alone 64K-bit dual-port memory systems requiring high-speed data buffering.
• Master/Slave dual-port configurations for expanding data bus widths to 16 bits or more in complex architectures.
• Industrial control systems requiring reliable asynchronous data exchange between processing units.
• Battery-backed applications utilizing the device's low-power standby modes for data retention.

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Ensure compatibility with existing PCB footprints for the 64-TQFP configuration. Validate electrical specifications against current system requirements given the discontinuation. Review replacement options if long-term supply stability is critical for production.

Selection Notes

Select this component when true dual-port functionality with hardware arbitration is required for asynchronous data sharing. Consider the 15 ns access speed and 64Kb density for intermediate buffering tasks. Evaluate the 64-TQFP package constraints against available board space. Assess the need for semaphore support to simplify software-driven synchronization protocols in multi-master environments.

Part Context

The 7005S15PF8 belongs to the Renesas 7005 series of dual-port SRAMs, designed for high-performance data communication between processors. This specific variant offers a 15 ns access time, balancing speed and power efficiency. The series supports various package options including TQFP and PLCC, catering to different design integration needs. It serves as a key building block for systems requiring non-blocking memory access.

Replacement Considerations

The 7005L15PFG8 is listed as an upgrade substitute by the manufacturer. Verify pinout compatibility and electrical parameter alignment before substitution. Check for any changes in package dimensions or thermal characteristics that may impact existing designs.
