Overview
The Renesas Electronics Corporation 71V321S55J is a static random access memory device featuring a storage capacity of 16 kbit organized as 2 k x 8. It operates with an asynchronous parallel interface and provides a maximum access time of 55 ns. The component supports a supply voltage range from 3 V to 3.6 V, with a maximum power current consumption of 115 mA. Designed for surface mount installation, it utilizes a PLCC-52 package. The device functions within a commercial temperature range of 0°C to +70°C.
Feature Summary
- Dual-port architecture enabling independent simultaneous read and write operations
- Asynchronous operation compatible with standard logic interfaces
- Single data rate (SDR) transfer mechanism
Applications
- Real-time data buffering in industrial control systems
- Cache memory implementation in embedded processors
- Data storage in telecommunications equipment
Procurement Notes
Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for moisture sensitivity handling procedures during storage and assembly. Validate pin compatibility with existing PCB footprints before integration.
Selection Notes
Evaluate thermal performance within the specified commercial temperature range. Ensure supply voltage stability between 3 V and 3.6 V for reliable operation. Consider package constraints associated with the PLCC-52 form factor. Assess system timing requirements against the 55 ns access speed limitation.
Part Context
This component belongs to the 71V321S series of dual-port SRAMs manufactured by Renesas Electronics. It serves as a high-speed memory solution for applications requiring concurrent port access. The series offers various speed grades and packaging options to suit different design needs.
Replacement Considerations
