70T3519S133BC8

Memory IC Overview

The Renesas 70T3519S133BC8 is a high-speed synchronous dual-port static random-access memory (SRAM) device. It features a storage organization of 256K words by 36 bits, providing a total capacity of 9 Mbit. The component supports a maximum clock frequency of 133 MHz with an access time of 4.2 ns. It operates on a single 2.5V power supply within a voltage range of 2.4V to 2.6V. The device utilizes a parallel interface and is housed in a 256-pin CABGA package measuring 17x17 mm.

Memory IC Feature Summary

• Supports simultaneous independent access to the same memory location from both ports
• Enables depth expansion through dual chip enable functionality without additional logic
• Provides selectable pipelined or flow-through output modes for optimized data throughput

Memory IC Applications

• High-performance networking equipment requiring low-latency data buffering
• Telecommunications systems utilizing burst data transfer protocols
• Industrial automation controllers needing reliable synchronous memory interfaces

Memory IC Procurement Notes

Verify the specific suffix BC8 against official Renesas documentation to confirm the exact package type and moisture sensitivity level. Ensure compatibility with 2.5V I/O standards and check for RoHS compliance status as indicated in current datasheets. Confirm availability and lead times directly with authorized distributors, as this component may have limited stock or end-of-life considerations.

Memory IC Selection Notes

Select this component when a design requires symmetric dual-port access with high bandwidth capabilities. It is suitable for applications demanding strict timing synchronization between two processors or controllers. Consider the 256-pin CABGA footprint for board space constraints and verify thermal management requirements for continuous operation at 133 MHz.

Memory IC Part Context

This part belongs to the Renesas 70T3519 series of synchronous dual-port SRAMs. These devices are engineered for high-speed data processing tasks where concurrent read/write operations are critical. The series offers various speed grades and packaging options to accommodate different system performance levels and physical integration requirements.

Memory IC Replacement Considerations

Check for direct pin-compatible substitutes within the 70T3519 family that match the 133 MHz speed grade. Verify if alternative packages such as FPBGA-208 variants offer equivalent electrical characteristics while fitting the existing PCB layout.
