Overview
The 71V3559S80BG is a 4.5Mb synchronous single data rate (SDR) zero-burst SRAM manufactured by Renesas Electronics Corporation. It features a parallel interface with an access time of 8 ns and operates within a supply voltage range of 3.135V to 3.465V. The device is organized as 256K x 18 bits and utilizes a 119-pin PBGA package measuring 14x22 mm. Designed for surface mount installation, it supports an operating temperature range from 0°C to 70°C.
Feature Summary
- Supports synchronous SDR zero-burst memory operations via a parallel interface.
- Provides fast 8 ns access time for high-speed data retrieval.
- Operates on a standard 3.3V core power supply with defined voltage limits.
Applications
- High-performance embedded systems requiring fast random access memory
- Network infrastructure equipment utilizing parallel bus architectures
- Industrial control units needing reliable volatile storage
Procurement Notes
Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity level handling procedures before assembly. Check for RoHS compliance variations in legacy stock. Ensure design-in compatibility with existing PCB footprints for the 119-PBGA configuration.
Selection Notes
Select this model when an 8 ns access speed is required for 4.5Mb capacity in a compact BGA form factor. Compare against other suffixes like S85 or S75 if timing requirements differ. Consider the 119-PBGA footprint constraints during layout. Evaluate thermal performance within the specified commercial temperature range.
Part Context
This part belongs to the 71V3559 family of synchronous SRAMs. It shares architectural similarities with variants offering different access times and packaging options. The series is designed for applications demanding high bandwidth and low latency in parallel memory interfaces.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify availability of alternative speeds such as 71V3559S75BG or 71V3559S85BG if timing adjustments are permissible.
