Overview
The Renesas 71V65903S80PFG8 is a 9Mb (512K x 18) synchronous static random-access memory (SRAM) IC. It utilizes Single Data Rate Zero Bus Turnaround (ZBT) technology for high-speed parallel data transfer with an access time of 8 ns. The device operates on a single 3.3V power supply within the range of 3.135V to 3.465V. It is housed in a 100-lead Thin Quad Flatpack (TQFP) package measuring 14x14 mm and supports an industrial operating temperature range from -40°C to +85°C.
Feature Summary
- Supports Single Data Rate Zero Bus Turnaround (ZBT) architecture for efficient parallel data throughput without bus turnaround latency penalties.
- Features a 18-bit wide data interface organized as 512K words by 18 bits, suitable for complex data processing applications.
- Operates at high speed with an 8 ns access time, enabling rapid data retrieval for real-time system requirements.
Applications
- High-performance embedded systems requiring fast volatile data storage
- Industrial control units needing reliable SRAM interfaces
- Telecommunications equipment utilizing ZBT memory protocols
Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status and specific suffix variations against official datasheets. Check for end-of-life notices or last-time-buy notifications prior to procurement decisions. Ensure packaging specifications match design requirements.
Selection Notes
Select this component when a 9Mb capacity with 18-bit width is required. Choose based on the need for 8 ns access speeds and ZBT protocol compatibility. Consider the 100-TQFP package for surface-mount assembly constraints. Verify voltage tolerance and temperature range suitability for the target environment.
Part Context
This part belongs to the IDT 71V65903 family of synchronous SRAMs. It represents a specific variant optimized for industrial temperatures and packaged in TQFP format. The family is designed for applications demanding high bandwidth and low latency in parallel memory architectures.
Replacement Considerations
Check for direct pin-compatible alternatives within the same ZBT SRAM family. Verify if newer revisions offer improved availability or updated packaging options while maintaining electrical equivalence.
