7005S20PF8

Overview

The Renesas Electronics Corporation 7005S20PF8 is an asynchronous dual-port static random-access memory (SRAM) with a density of 64 kilobits, organized as 8K x 8 bits. It features a parallel interface and operates within a core voltage range of 4.5V to 5.5V. The device has a maximum access time of 20 nanoseconds and supports a maximum supply current of 290 mA. It functions in an industrial temperature range from 0°C to +70°C and is housed in a surface-mount PLCC-68 package.

Feature Summary

• True dual-ported memory cells enabling simultaneous independent reads of the same memory location by both ports.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity between master and slave configurations.
• Automatic power-down feature controlled by chip enable signals to achieve low standby power consumption modes.

Applications

• Stand-alone 64K-bit dual-port memory systems
• Master/Slave dual-port RAM combinations for 16-bit or wider word systems
• Industrial control applications requiring high-speed data buffering

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm package integrity and moisture sensitivity handling procedures prior to assembly. Review datasheet specifications for lead-free status and environmental compliance requirements relevant to your manufacturing standards.

Selection Notes

Select this component when simultaneous bidirectional access to shared memory is required without external arbitration circuitry. Ensure system voltage aligns with the 4.5V to 5.5V operating range. Consider the PLCC-68 footprint for PCB layout compatibility and verify thermal management capabilities for the specified industrial temperature range.

Part Context

This part belongs to the 7005 series of high-speed dual-port SRAMs manufactured by Renesas Electronics. The series provides flexible memory solutions for embedded systems needing concurrent data access. Variants in the family differ primarily in access speed and packaging options while maintaining consistent architectural features and functionality.

Replacement Considerations

Publicly confirmed substitute part numbers include IDT7005S20J8. Verify pinout compatibility and electrical specifications before substitution.
