70T3519S166BCI

Memory IC Overview

The 70T3519S166BCI is a synchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a storage capacity of 9 Mbit organized as 256K x 36 bits. The device supports a maximum clock frequency of 166 MHz with an access time of 3.6 ns. It operates within a supply voltage range of 2.4 V to 2.6 V and has a maximum power supply current of 510 mA. The component is housed in a 256-CABGA package measuring 17x17 mm and is rated for an operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports simultaneous independent access to the same memory location via two separate ports.
• Features full synchronous operation on both ports with parallel interface.
• Includes collision detection capabilities for managing concurrent access conflicts.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in network processing equipment
• Data storage in industrial control systems requiring dual-port access

Memory IC Procurement Notes

Verify the specific suffix BCIG or BCI against official Renesas documentation to confirm package type and environmental compliance status. Confirm moisture sensitivity level requirements for surface mount assembly processes. Check for any product change notifications regarding lead content or RoHS status updates prior to ordering.

Memory IC Selection Notes

Select this component when a high-density 9 Mbit synchronous dual-port SRAM is required for applications needing 166 MHz performance. Ensure the design accommodates the 256-pin CABGA footprint and the specified 2.5V nominal supply voltage constraints. Verify that the thermal management strategy supports the maximum operating current under worst-case conditions.
