7005S20PFI

Overview

The Renesas Electronics Corporation 7005S20PFI is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 64 kbit, organized as 8k x 8 words. The device supports asynchronous parallel interface operations with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a 64-lead Thin Quad Flat Package (TQFP). The component is designed for surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface supporting standard TTL-compatible logic levels
• Integrated hardware control features including busy flags, interrupts, semaphores, and master/slave modes

Applications

• High-speed data buffering in telecommunications equipment
• Real-time signal processing systems requiring concurrent data access
• Industrial automation controllers managing complex I/O tasks

Procurement Notes

Verify the specific suffix designation carefully, as package types and thermal ratings vary significantly across the 7005S series. Confirm that the selected variant matches the required lead count and physical dimensions for the target PCB footprint. Ensure compliance with applicable environmental regulations, noting that certain variants may not meet current RoHS standards. Validate moisture sensitivity levels prior to assembly to prevent damage during soldering processes.

Selection Notes

Select this component when a design requires true dual-port memory capabilities for high-throughput applications. Compare access times against system clock requirements to ensure timing margins are met. Evaluate the available package options, such as PLCC or TQFP, based on board space constraints and thermal management needs. Consider the operational temperature range to guarantee reliability under extreme environmental conditions.

Part Context

The 7005S20PFI belongs to the Renesas 7005S family of dual-port SRAMs, which are widely utilized in embedded systems demanding fast, independent memory access. This specific model represents a 20 ns speed grade variant within the series. The family is known for its robust semaphore and interrupt mechanisms, facilitating efficient multi-master communication without external arbitration logic.
