71V65803S133BG

Overview

The 71V65803S133BG is a 9Mb synchronous single data rate (SDR) zero bus turnaround (ZBT) static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a parallel interface with a maximum clock frequency of 133 MHz and an access time of 4.2 ns. The device operates within a supply voltage range of 3.135V to 3.465V and is housed in a 119-pin plastic ball grid array (PBGA) package measuring 14x22 mm. It supports a memory organization of 512K x 18 bits and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Supports high-speed parallel data transfer via a synchronous SDR ZBT architecture
• Provides fast 4.2 ns access time for low-latency memory operations
• Utilizes a compact 119-pin PBGA surface-mount package for board integration

Applications

• High-performance embedded systems requiring fast volatile storage
• Industrial control equipment with strict timing requirements
• Telecommunications infrastructure hardware

Procurement Notes

Verify component authenticity through authorized distributors as the part is officially discontinued. Confirm RoHS compliance status, which indicates non-compliance with current environmental standards. Check for moisture sensitivity level 3 handling requirements during assembly. Ensure replacement strategies account for the end-of-life status when designing new products.

Selection Notes

Select this component only if legacy compatibility with the 71V65803 family is required. Evaluate the 133 MHz speed grade against system clock constraints. Consider the 119-PBGA footprint for PCB layout limitations. Assess the 3.3V nominal supply requirement against available power rails. Verify that the commercial temperature range meets operational environment specifications.

Part Context

This SRAM belongs to the IDT 71V65803 series, designed for applications demanding high bandwidth and low latency. The series utilizes advanced CMOS technology to deliver dense memory configurations in small form factors. It serves as a critical buffer or cache memory solution in digital signal processing and networking applications where rapid data access is essential.
