7005S20PFI8

Overview

The Renesas Electronics Corporation 7005S20PFI8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 64 kbit organized as 8K x 8 bits. The component features a parallel interface with a maximum access time of 20 ns. It operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V. The device is housed in a 100-TQFP surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads and writes from two separate ports without conflict.
• Integrated hardware support for semaphore signaling and port arbitration logic to manage data integrity between master and slave configurations.
• Automatic power-down functionality controlled by chip enable signals to minimize standby power consumption during inactive periods.

Applications

• Stand-alone 64K-bit dual-port RAM systems requiring high-speed data buffering.
• Master/Slave dual-port RAM configurations for expanding data bus widths to 16 bits or more in complex embedded architectures.
• Industrial control systems requiring reliable data exchange between processors under varying environmental conditions.

Procurement Notes

Verify the specific suffix PFI8 against official Renesas documentation to confirm the exact package type and temperature grade. Confirm RoHS compliance status as legacy variants may differ. Check current lifecycle status as this series may be discontinued or subject to last-time buy restrictions. Ensure ECAD models match the 100-TQFP footprint requirements for your design.

Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration circuitry. Compare access times and package pin counts against alternative speeds if board space is constrained. Verify that the 5V TTL-compatible I/O levels align with the interfacing microcontroller or processor voltage domains. Consider thermal dissipation capabilities within the TQFP package for the target application environment.

Part Context

This part belongs to the Renesas 7005 family of high-speed dual-port SRAMs. The family offers various access speeds and packaging options to suit different performance and form-factor needs. These devices are designed for applications demanding fast, conflict-free data sharing between multiple masters or processors in real-time systems.

Replacement Considerations

Check for direct cross-reference part numbers such as IDT7005S20PFI8. Verify functional compatibility regarding pinouts, voltage levels, and semaphore logic before substitution. Ensure any replacement maintains the same 100-TQFP package dimensions and thermal characteristics.
