7005S12PFI

Overview

The Renesas Electronics Corporation 7005S12PFI is a high-speed 8K x 8 Dual-Port Static RAM with a 64 kbit storage capacity. It features a parallel asynchronous interface and operates within a voltage range of 4.5 V to 5.5 V, with a maximum supply current of 250 mA. The component provides a fast access time of 12 ns and supports an industrial temperature range from -40°C to +85°C. It is housed in a 64-pin TQFP surface-mount package.

Feature Summary

• True dual-ported memory cells enabling simultaneous independent reads and writes from either port without conflict
• On-chip hardware support for semaphore signaling and interrupt flags to facilitate efficient master/slave coordination
• Automatic power-down feature controlled by chip enable signals to achieve very low standby power consumption
• TTL-compatible single 5V power supply operation ensuring compatibility with standard logic families

Applications

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

Procurement Notes

Verify RoHS compliance status as it varies by specific manufacturing lot and revision. Confirm the exact suffix designation matches the required temperature grade and package type. Check for end-of-life notifications or alternative part recommendations from the manufacturer. Ensure ECAD models are updated to reflect the correct pinout and footprint dimensions for the 64-TQFP package.

Selection Notes

Select this component when simultaneous bidirectional data transfer is required between two processors or controllers. The 12 ns access speed suits high-throughput applications compared to slower variants in the series. Consider the TQFP-64 package for surface-mount assembly requirements. Evaluate the need for industrial temperature ratings versus commercial grades based on the operational environment constraints.

Part Context

This device belongs to the Renesas 7005L/S series of dual-port SRAMs. It shares architectural similarities with parts like the 7005L25PFI but offers faster 12 ns access times. The series is designed for flexible integration in embedded systems requiring shared memory resources without external arbitration logic overhead.

Replacement Considerations

The IDT7005S12PFI is a confirmed equivalent part number from the same product lineage. Verify pin compatibility and electrical specifications before substitution. Other series members such as the 7005L25PFI offer similar functionality with different access speeds.
