71V65703S85BGGI8

Overview

The 71V65703S85BGGI8 is a synchronous static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It features a storage capacity of 9 Mbit, organized as 256K x 36 bits. The device supports a parallel interface with an access time of 8.5 ns and a maximum clock frequency of 87 MHz. It operates within a supply voltage range of 3.135 V to 3.465 V and has a maximum power consumption of 210 mA. The component is housed in a 119-pin PBGA package measuring 14x22 mm and is rated for industrial operating temperatures from -40°C to +85°C.

Feature Summary

• Supports Zero Bus Turnaround (ZBT) technology to eliminate dead bus cycles during read/write transitions.
• Includes address, data-in, and control signal registers for synchronous operation.
• Provides flow-through outputs without output data registers.
• Capable of burst mode operations delivering four cycles of data for a single address.

Applications

• High-performance embedded systems requiring fast data buffering
• Network infrastructure equipment
• Industrial automation controllers
• Telecommunications base stations

Procurement Notes

Verify the specific suffix 'I8' against official Renesas documentation to confirm packaging details such as reel or cut tape specifications. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Check for any Product Change Notifications (PCN) regarding substrate changes or label updates issued in 2022. Ensure compatibility with your board's thermal management capabilities given the 210 mA maximum current draw.

Selection Notes

Select this component when a 36-bit wide data path is required for high-speed synchronous applications. Compare access times and pin counts against alternative SRAM families if space constraints exist. Verify that the 119-PBGA package footprint matches your PCB design rules. Consider the industrial temperature range (-40°C to +85°C) if the application environment varies significantly.

Part Context

This part belongs to the 71V65703/903 family of ZBT Synchronous SRAMs. It is functionally similar to other variants in the series but distinguished by its specific speed grade (8.5 ns), package type (PBGA), and organizational structure (256K x 36). The 'I8' suffix typically denotes specific packaging or environmental qualifications defined by the manufacturer.

Replacement Considerations

Publicly confirmed substitute part numbers include IDT71V67703S85BG. Verify electrical compatibility and pinout alignment before substitution.
