71V67603S166BQG8

Overview

The IDT71V67603S166BQG8 is a synchronous single data rate static random-access memory integrated circuit manufactured by Renesas Electronics Corporation. It provides a total storage capacity of 9 megabits, organized as 256 kilowords by 36 bits. The device supports parallel interface operations with a maximum clock frequency of 166 MHz and features an access time of 3.5 nanoseconds. It operates within a supply voltage range of 3.135 volts to 3.465 volts and is designed for commercial temperature environments ranging from 0°C to 70°C. The component is housed in a 165-terminal cavity ball grid array package measuring 13 by 15 millimeters.

Feature Summary

• Supports high-speed parallel data transfer via synchronous single data rate architecture
• Provides wide 36-bit data bus width for efficient system integration
• Operates on a single 3.3-volt power supply rail
• Utilizes volatile memory technology requiring no refresh cycles

Applications

• High-performance computing systems requiring fast buffer memory
• Network infrastructure equipment utilizing wide data buses
• Industrial automation controllers needing rapid data processing
• Telecommunications hardware demanding low-latency memory access

Procurement Notes

Verify the exact suffix designation during procurement, as variations such as BQG versus BQG8 may indicate differences in packaging or manufacturing lot specifications. Confirm that the supplier source aligns with authorized distribution channels to ensure component authenticity. Check current lifecycle status, as this specific part number may be subject to discontinuation notices or product change notifications issued by the manufacturer. Ensure compatibility with existing board designs regarding the 165-CABGA footprint and thermal requirements.

Selection Notes

Select this component when a design requires a 36-bit wide memory interface synchronized with a system clock up to 166 MHz. It is suitable for applications where standard 32-bit widths are insufficient and asynchronous SRAM latency is too high. Consider the 165-ball BGA package constraints for PCB layout and thermal management. Evaluate the 3.3-volt operating requirement against the target system's power delivery network capabilities.

Part Context

This device belongs to the 71V67603 series of synchronous SRAMs produced by Renesas Electronics. The series is engineered for embedded systems and networking applications that demand high throughput and deterministic timing. The 71V67603 variant specifically offers a 9-megabit density with a 36-bit organization, distinguishing it from narrower 8-bit or 16-bit counterparts in the same family.
