7005S17PF8

Overview

The Renesas Electronics Corporation 7005S17PF8 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 5V power supply within a 4.5V to 5.5V range. The device provides a maximum access time of 17 nanoseconds and supports simultaneous independent reads from both ports. It is housed in a 64-pin Thin Quad Flat Package (TQFP) with a 0.8mm pitch.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access by two masters
• On-chip hardware support for semaphore signaling and port arbitration logic
• Integrated interrupt flag functionality for efficient status monitoring
• Automatic power-down mode controlled by chip enable signals

Applications

• Stand-alone 64K-bit dual-port memory systems
• Master/Slave dual-port configurations for 16-bit or wider data bus expansion
• Battery-backed operation requiring 2V data retention capabilities
• Industrial control applications operating within the commercial temperature range

Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Renesas Electronics. Verification of availability requires checking authorized distributors for remaining stock or surplus inventory. Sourcing should prioritize verified suppliers to ensure authenticity, as end-of-life products may have varying storage conditions affecting reliability.

Selection Notes

Select this part when a true dual-port SRAM with 17ns access speed is required for asynchronous communication between two processors. Ensure the design accommodates the 64-pin TQFP package dimensions and 5V TTL-compatible I/O levels. Verify that the application environment stays within the 0°C to +70°C operating temperature range specified for this suffix.

Part Context

The 7005 series represents a family of high-speed dual-port RAMs designed for flexible system integration. The 7005S17 variant specifically targets applications needing fast, non-blocking memory access. This model belongs to the commercial grade subset, distinct from industrial or military variants which offer extended temperature ranges or enhanced radiation hardness.
