70T3519S200BCG

Memory IC Overview

The Renesas Electronics Corporation 70T3519S200BCG is a synchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 9 Mbit organized as 256K x 36 bits. The component supports a maximum clock frequency of 200 MHz with an access time of 3.4 ns. It operates on a single 2.5V power supply and utilizes a parallel interface. The device is housed in a 256-pin CABGA package measuring 17x17 mm.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to the same memory location by two separate controllers.
• Full synchronous operation on both ports utilizing a common clock signal for data transfer.
• Parallel interface design optimized for high-speed data throughput applications.

Memory IC Applications

• High-performance networking equipment requiring rapid packet buffering
• Telecommunications systems needing low-latency data processing
• Industrial automation controllers demanding reliable real-time memory access

Memory IC Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure that the procurement channel provides traceability for the 256-CABGA package type. Confirm moisture sensitivity level handling requirements prior to assembly to prevent damage during soldering processes.

Memory IC Selection Notes

Select this component when a system requires simultaneous read/write operations from two distinct masters without arbitration delays. The 200 MHz speed grade suits designs needing minimal cycle latency. Verify that the 2.5V I/O voltage levels match the host processor specifications to ensure signal integrity across the parallel bus connections.

Memory IC Part Context

This part belongs to the 70T3519 series of synchronous dual-port SRAMs. The series offers various speed grades and packaging options to accommodate different performance and form factor requirements. The 200 MHz variant represents a high-performance option within this family, designed for bandwidth-intensive digital signal processing tasks.

Memory IC Replacement Considerations

Consult official substitution lists for compatible parts such as the 70T3519S166BCI or 70T3519S133BCI if lower clock speeds are acceptable. Verify that any alternative maintains the 256K x 36 organization and 256-pin CABGA footprint to ensure mechanical fit.
