Overview
The Renesas Electronics 7005L20PFI8 is an asynchronous dual-port static random-access memory (SRAM) IC. It offers a total storage capacity of 64 kbit, organized as 8K x 8 bits. The device features a parallel interface with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum power supply current of 280 mA. The component is rated for an operating temperature range from -40°C to +85°C and is housed in a 64-pin TQFP surface-mount package.
Feature Summary
- Provides independent read/write ports for simultaneous data access
- Supports asynchronous operation without clock synchronization requirements
- Utilizes standard parallel interface for straightforward integration
Applications
- Asynchronous data buffering in communication systems
- Cache memory implementation in embedded processors
- Data storage in industrial control equipment
Procurement Notes
Verify the RoHS compliance status carefully, as official documentation indicates this specific part number may be non-compliant or obsolete. Confirm the lifecycle status with the manufacturer before finalizing design-in decisions. Ensure that the 64-TQFP package dimensions match the target PCB footprint exactly. Check for moisture sensitivity levels if the component has been stored for extended periods.
Selection Notes
Select this component when a 64 kbit dual-port SRAM with 20 ns speed is required. It is suitable for applications needing independent port access at 5V logic levels. Consider the TQFP-64 package constraints during layout. Evaluate alternatives if RoHS compliance is mandatory, as this specific suffix may not meet current environmental standards.
Part Context
This part belongs to the 7005L series of dual-port SRAMs from Renesas Electronics. It shares architectural similarities with other members like the 7005L25PFI but differs in access speed and packaging options. The series is designed for high-performance asynchronous memory applications requiring independent port functionality.
Replacement Considerations
The IDT7005L20PFI8 is listed as an alias for this part number. Verify pin compatibility and electrical specifications before substitution. Other family members like the 7005L25PFI offer different access times and should be evaluated based on timing requirements.
