71V65603S100PFG8

Overview

The Renesas Electronics Corporation 71V65603S100PFG8 is a 9 Mbit synchronous static random access memory (SRAM) device. It features a parallel interface with a memory organization of 256K x 36 bits. The component operates at a maximum clock frequency of 100 MHz and provides an access time of 5 ns. It functions within a supply voltage range of 3.135 V to 3.465 V and supports surface mount installation in a 165-CABGA package measuring 13x15 mm. The device is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Eliminates dead bus cycles during read-to-write or write-to-read transitions using Zero Bus Turnaround (ZBT) technology
• Supports high-speed data transfer via a 100 MHz synchronous clock interface
• Provides 36-bit wide data paths suitable for complex processing architectures

Applications

• High-performance networking equipment requiring fast buffer memory
• Telecommunications systems utilizing synchronous data handling
• Industrial control units needing reliable volatile storage

Procurement Notes

Verify the specific suffix PFG8 against official Renesas documentation to confirm package type and temperature rating, as suffixes define physical attributes. Confirm RoHS compliance status directly with the manufacturer, as historical records indicate variations across similar packages. Check for End-of-Life notices, as this component family has faced discontinuation events. Ensure compatibility with existing board layouts regarding the 165-CABGA footprint before procurement.

Selection Notes

Select this component when a 36-bit data width is required for system integration. The 100 MHz speed class offers a balance between performance and power consumption compared to faster variants. Consider the 165-CABGA package for applications requiring dense surface-mount assembly. Verify that the 3.3V I/O levels match the host processor specifications to ensure signal integrity without additional level shifting circuitry.

Part Context

This part belongs to the IDT 71V65603 series of ZBT SRAMs. It shares architectural similarities with other members like the 71V65602 and 71V65703, differing primarily in speed grades and package options. The series is designed for applications demanding high throughput and low latency in parallel memory environments.

Replacement Considerations

Publicly confirmed substitute part numbers include 71V65603S100PFG and 71V65603S100BG. Verify pinout and electrical specifications against datasheets before substitution.
