70T3519S166BFG8

Memory IC Overview

The 70T3519S166BFG8 is a high-speed synchronous dual-port static random access memory manufactured by Renesas Electronics. It features a storage capacity of 4.5 Mbit organized as 256K x 18 bits. The device supports a maximum clock frequency of 166 MHz with an access time of 3.6 ns. It operates on a parallel interface and requires a supply voltage between 2.4 V and 2.6 V. The component is housed in a 208-CABGA package measuring 15x15 mm and functions within a temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to the same memory location from two separate ports.
• Synchronous operation optimized for burst data flow applications supporting both unidirectional and bidirectional transfer modes.
• Automatic power-down capability controlled by chip enables, allowing individual port circuitry to enter low standby power states.

Memory IC Applications

• Network routers and switches requiring high-throughput packet buffering
• Telecommunications equipment utilizing fast data processing and protocol handling
• Industrial automation systems needing reliable real-time data storage

Memory IC Procurement Notes

Verify current availability status as this component may be subject to discontinuation or limited production runs. Confirm package compatibility and moisture sensitivity levels before ordering. Ensure supply chain sources are authorized distributors to guarantee authenticity. Check for alternative packaging options if standard trays are unavailable. Validate technical specifications against specific design requirements prior to procurement.

Memory IC Selection Notes

Select this component for designs requiring high-speed synchronous dual-port memory with 18-bit word width. Ensure the system voltage aligns with the specified 2.4 V to 2.6 V operating range. Consider the 208-CABGA package dimensions for PCB layout constraints. Verify that the application benefits from simultaneous port access rather than single-port alternatives.

Memory IC Part Context

This part belongs to the 70T3319/19/99 series of synchronous dual-port SRAMs. It shares architectural similarities with other members like the 70T3319 and 70T3589 but differs in density and organization. The series is designed for high-performance embedded applications requiring fast data throughput and flexible I/O configurations.
