71V67603S150BQI

Overview

The 71V67603S150BQI is a synchronous single data rate static random access memory manufactured by Renesas Electronics. It provides a storage capacity of 9 Mbit organized as 256K x 36 bits. The device supports a maximum clock frequency of 150 MHz with an access time of 3.8 ns. It operates within a voltage range of 3.135 V to 3.465 V and features a parallel interface. The component is housed in a 165-CABGA package suitable for surface mount installation.

Feature Summary

• Supports high-speed synchronous data transfer via a parallel interface architecture
• Provides wide 36-bit data word organization for efficient bus utilization
• Operates reliably across extended industrial temperature ranges

Applications

• High-performance embedded systems requiring fast local memory
• Industrial automation controllers needing reliable data buffering
• Telecommunications equipment utilizing synchronous SRAM interfaces

Procurement Notes

Verify the specific suffix BQI against official Renesas documentation to confirm package type and moisture sensitivity level. Confirm RoHS compliance status as historical records indicate variations within this family. Check current production lifecycle status to ensure availability for long-term designs. Validate pin compatibility if replacing older variants from the same series.

Selection Notes

Select this component when a 36-bit wide data path is required for system integration. Ensure the design accommodates the 165-pin CABGA footprint and thermal requirements. Verify that the host controller supports the necessary synchronous protocol and voltage levels. Consider the 150 MHz speed grade relative to system timing constraints.

Part Context

This part belongs to the 71V67603 series of synchronous SRAMs from Renesas. It shares architectural similarities with other members like the 71V67603S133BGGI but differs in speed grade and package configuration. The series is designed for applications demanding high bandwidth and low latency memory solutions.

Replacement Considerations

The 71V67603S150BQ is listed as a similar alternative, though it may differ in operating temperature range or compliance status. Cross-reference datasheets for pinout and electrical parameter compatibility before substitution.
