70T3519S166BCGI

Memory IC Overview

The 70T3519S166BCGI is a synchronous dual-port static random access memory manufactured by Renesas Electronics. 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 on a single 2.5V power supply within a voltage range of 2.4V to 2.6V and has a maximum power current of 510 mA. The component utilizes a parallel interface and is housed in a 256-pin CABGA package measuring 17x17 mm. It functions within an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Simultaneous independent access to the same memory location via two separate ports
• Full synchronous operation on both ports for high-speed data transfer
• Selectable pipelined or flow-through output modes for flexible system integration
• Integrated JTAG functionality for boundary scan testing and debugging

Memory IC Applications

• High-performance networking equipment requiring low-latency data buffering
• Telecommunications systems utilizing burst data processing
• Industrial automation controllers needing reliable dual-access memory
• Embedded systems requiring synchronous SRAM with collision detection

Memory IC Procurement Notes

Verify that the specific suffix BCGI corresponds to the required lead-free status and moisture sensitivity level, as RoHS compliance details may vary by manufacturing batch. Confirm the package dimensions match the target PCB footprint precisely. Ensure the design accounts for the specified operating temperature range and power consumption limits during peak activity. Check for any recent product change notices regarding pinout or electrical characteristics before finalizing the bill of materials.

Memory IC Selection Notes

Select this component when a 9 Mbit synchronous dual-port SRAM with a 36-bit word width is required. The 166 MHz speed grade suits applications demanding fast data throughput. Compare against the 70T3519S133 variant if lower power consumption is prioritized over maximum clock speed. Ensure the system architecture supports LVTTL I/O levels compatible with the 2.5V core voltage. Verify that the 256-CABGA package is feasible for the assembly process.

Memory IC Part Context

This part belongs to the 70T3519 series of synchronous dual-port RAMs from Renesas. The series offers various speed grades and package options to accommodate different performance and form factor requirements. These devices are designed for applications requiring simultaneous read/write operations from two distinct masters without external arbitration logic.

Memory IC Replacement Considerations

The 70T3519S133BCGI is a documented similar alternative within the same family, offering identical organization but a lower 133 MHz clock frequency.
