7005S12PF8

Overview

The Renesas Electronics Corporation 7005S12PF8 is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It features a storage organization of 8K x 8 bits, providing a total density of 64 kilobits. The device supports simultaneous independent access from two ports with a specified access time of 12 nanoseconds. It operates on a single 5.0 V power supply and utilizes TTL-compatible I/O levels. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) with a 0.8 mm pitch.

Feature Summary

• True dual-ported memory architecture enabling simultaneous reads of the same memory location from both ports.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage bus conflicts.
• Integrated interrupt flag functionality to signal status changes between master and slave operations.
• Automatic power-down feature controlled by chip enable inputs to minimize standby power consumption.

Applications

• Stand-alone high-speed data buffering in parallel processing systems.
• Master/Slave dual-port configurations for expanding data bus widths to 16 bits or more.
• Real-time data exchange interfaces requiring low-latency concurrent access.
• Battery-backed memory applications utilizing 2V data retention capabilities.

Procurement Notes

Verify component authenticity through authorized channels as this part may be discontinued. Confirm package integrity and moisture sensitivity level handling requirements before assembly. Check for lead-free compliance status against specific project regulations. Ensure voltage supply stability within the 4.5V to 5.5V range during operation.

Selection Notes

Select this component when simultaneous bidirectional access to shared memory is required without external arbitration delays. The 12 ns speed suits high-frequency asynchronous interfaces. Consider the TQFP package for surface-mount assembly constraints. Evaluate power consumption needs against the automatic power-down features available in this series.

Part Context

This device belongs to the 7005 family of dual-port SRAMs manufactured by Renesas Electronics. The family offers various access speeds and packaging options to suit different system timing and physical layout requirements. It serves as a bridge between disparate processing units needing fast, conflict-managed memory sharing.

Replacement Considerations

Check for IDT7005S12PF8 as a potential equivalent designation. Verify pin compatibility and electrical specifications against other 7005 series variants with similar access times.
