70T3319S133BFI8

Memory IC Overview

The Renesas 70T3319S133BFI8 is a high-speed synchronous dual-port static random-access memory (SRAM) with a density of 4.5 Mbit, organized as 256K words by 18 bits. It supports an I/O clock frequency up to 133 MHz and features a 4.2 ns access time. The device operates with a 3.3V core voltage and selectable 3.3V or 2.5V I/O supplies. It is housed in a 208-pin CABGA package measuring 15x15 mm with a 0.8 mm pitch.

Memory IC Feature Summary

• Dual-port architecture enables simultaneous independent access to the same memory location from two separate ports.
• Supports both pipelined and flow-through output modes for flexible data transfer optimization.
• Includes JTAG functionality for boundary scan testing and system diagnostics.
• Features automatic power-down capabilities controlled by chip enable signals to minimize standby power consumption.

Memory IC Applications

• High-performance networking equipment requiring low-latency data buffering
• Industrial automation systems utilizing burst data processing
• Telecommunications infrastructure supporting bidirectional data flow

Memory IC Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm that the specific suffix matches the required package type and voltage specifications. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Request official datasheets and quality certificates prior to finalizing procurement agreements to guarantee supply chain integrity.

Memory IC Selection Notes

Select this component when simultaneous read/write operations are critical for system throughput. Consider the 208-pin CABGA package for surface-mount applications requiring robust thermal performance. Evaluate the need for JTAG support if board-level testing is mandatory. Compare against single-port alternatives if only one interface is utilized to optimize cost and space.

Memory IC Part Context

This part belongs to the 70T3319 series of synchronous dual-port SRAMs designed for high-speed data handling. It shares architectural similarities with other members like the 70T3519 but differs in organization and voltage options. The series is optimized for applications demanding unidirectional or bidirectional data bursts with minimal latency.

Memory IC Replacement Considerations

Direct substitutes include the IDT70T3319S133BFI. Verify pin compatibility and electrical parameters before integration. Alternative packages such as TQFP or fpBGA variants exist within the same family but require mechanical redesign.
