71V65903S85BGGI

Overview

The Renesas 71V65903S85BGGI is a synchronous static random-access memory (SRAM) integrated circuit belonging to the ZBT family. It provides a total storage capacity of 9 Megabits, organized as 512K words by 18 bits. The device features a parallel interface with an access time of 8.5 nanoseconds and operates on a single 3.3-volt power supply within a range of 3.135 to 3.465 volts. It is housed in a 119-ball PBGA package measuring 14x22 millimeters and supports industrial temperature ranges.

Feature Summary

• Supports high-speed data transfer via a synchronous parallel interface architecture
• Provides reliable volatile data retention for real-time processing applications
• Integrates flow-through logic to minimize latency during read operations

Applications

• Industrial automation control systems
• Telecommunications network infrastructure equipment
