Memory IC Procurement Notes

Verify the specific suffix designation against official Renesas documentation, as variations exist within the 70T3519 series regarding packaging and environmental ratings. Confirm current production status, as certain variants in this family have been subject to discontinuance notifications. Ensure compatibility with existing board layouts due to the specific 256-CABGA footprint requirements.

Memory IC Selection Notes

Select this component when a high-density 9 Mbit synchronous SRAM is required for dual-port applications. The 166 MHz speed grade suits designs needing rapid data throughput. Verify that the system power supply strictly adheres to the 2.4 V to 2.6 V specification to ensure stable operation. Consider the industrial temperature range if the deployment environment experiences significant thermal fluctuations.

Memory IC Part Context

This part belongs to the 70T3519 series of high-speed synchronous dual-port SRAMs. The series is designed for burst data flow applications. Variants within the series differ primarily in organization density, such as 64K x 36 or 256K x 18 configurations, and package types like 208-pin CABGA.
