7005L15PFI

Overview

The Renesas Electronics Corporation 7005L15PFI is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 64 kbit organized as 8k x 8 bits. The device supports parallel interface communication with a maximum access time of 15 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 280 mA. The component is housed in a 64-TQFP surface-mount package with dimensions of 14x14 mm. It is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides independent read/write access to two ports simultaneously via asynchronous parallel interfaces.
• Supports high-speed data transfer with a 15 ns access time specification.
• Operates reliably across extended industrial temperature ranges.

Applications

• High-performance embedded systems requiring concurrent data access
• Industrial control units needing robust memory solutions
• Telecommunications equipment buffer applications

Procurement Notes

Verify the specific suffix PFI against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as historical records may vary. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans. Ensure compatibility with existing PCB footprints for the 64-TQFP form factor.

Selection Notes

Select this component when dual-port functionality is required for simultaneous master-slave operations. Compare access times against system clock requirements to ensure the 15 ns speed meets timing constraints. Evaluate power consumption limits given the 280 mA maximum current draw. Consider the industrial temperature rating if the application environment exceeds commercial standards.

Part Context

This part belongs to the 7005L series of dual-port SRAMs manufactured by Renesas Electronics. It serves as a legacy alternative to newer single-port or synchronous memories where independent port access is critical. The 7005L series is designed for applications demanding fast, non-blocking memory access between two distinct processors or logic blocks.

Replacement Considerations

Official substitutes include the 7005L15PFG variant, which offers a direct upgrade path with similar electrical characteristics but potentially updated packaging or compliance features. Verify pinout compatibility before substitution.
