Overview
The Renesas Electronics Corporation 7005S55PFI is a dual-port static random-access memory (SRAM) device with a storage capacity of 64Kb, organized as 8K words by 8 bits. It features asynchronous parallel interface operation with a maximum access time of 55 ns. The component operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 64-TQFP package measuring 14x14 mm. It is designed for commercial temperature ranges from 0°C to 70°C.
Feature Summary
- Provides independent read/write ports for simultaneous data access
- Supports asynchronous parallel interface operations
- Utilizes standard 64-pin thin quad flat pack packaging
Applications
- High-speed data buffering in embedded systems
- Cache memory implementation in microcontroller architectures
- Data storage in industrial control applications
Procurement Notes
Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate pin compatibility and electrical specifications against target system designs before integration. Check for available upgrade alternatives if long-term supply stability is required.
Selection Notes
Select this component when dual-port functionality is necessary for concurrent processor access. Ensure the design accommodates the 55 ns access time and 64-TQFP footprint. Verify that the operating environment remains within the specified commercial temperature limits. Consider power consumption characteristics relative to system thermal constraints.
Part Context
This device belongs to the Renesas 7005 series of dual-port SRAMs. It serves as a high-performance memory solution for applications requiring simultaneous access from two independent masters. The series offers various speed grades and package options to suit different system requirements.
Replacement Considerations
Consult manufacturer documentation for verified upgrade paths. Cross-reference pinouts and electrical parameters with potential substitute components to ensure functional compatibility.
