71P74604S200BQG

Overview

The IDT71P74604S200BQG is a high-speed synchronous Quad Data Rate (QDR) II SRAM manufactured by Integrated Device Technology. It features an 18 Mbit memory organization arranged as 1M x 18 bits. The device supports a clock frequency of 200 MHz, enabling data transfer rates up to 800 Mbps through four independent data ports. It operates with a supply voltage range of 1.7V to 1.9V and utilizes a 165-ball CABGA package measuring 13x15 mm.

Feature Summary

• Supports simultaneous read and write operations across four independent ports without bus turnaround dead cycles
• Utilizes positive clock-edge triggered registers for fully pipelined address, data, and control signals
• Features internally synchronized output buffer enable to eliminate external control requirements

Applications

• High-performance networking equipment requiring low-latency packet buffering
• Telecommunications infrastructure systems demanding high throughput
• Industrial automation controllers needing rapid data acquisition

Procurement Notes

Verify the specific suffix 'BQG' against official Renesas or IDT documentation to confirm pinout compatibility and RoHS status. Ensure the operating temperature range meets system requirements. Confirm availability as this component series may have discontinuation notices. Validate that the 1.7V to 1.9V supply voltage aligns with your power design constraints before procurement.

Selection Notes

Select this component when system architecture requires non-blocking concurrent access to shared memory resources. The QDR interface simplifies PCB routing by eliminating complex arbitration logic required by traditional dual-port SRAMs. Consider the 165-ball BGA package size for board space limitations. Verify that the 200 MHz speed grade matches the processor's maximum clock capability to avoid timing violations.

Part Context

This part belongs to the IDT71P74 family of QDR II SRAMs, designed for applications requiring deterministic latency and high bandwidth. The family shares common architectural features but varies in speed grades and density. The 71P74604 variant specifically targets mid-range capacity needs within high-speed data processing environments, bridging the gap between smaller buffers and larger, slower memory arrays.
