70T3319S133BFGI8

Memory IC Overview

The Renesas 70T3319S133BFGI8 is a high-speed synchronous dual-port static random-access memory (SRAM) device. It features a storage organization of 256K x 18 bits, providing a total capacity of 4.5 Mbit. The component supports clock frequencies up to 133 MHz with an access time of 4.2 ns. It operates within a voltage range of 2.4 V to 2.6 V and functions across a temperature range of -40°C to +85°C. The integrated circuit is housed in a 208-CABGA package measuring 15x15 mm.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through two distinct ports for concurrent data processing.
• Integrates collision detection logic to manage bus contention when both ports attempt access to the same address simultaneously.
• Includes built-in counters and interrupt capabilities to facilitate system monitoring and control signaling.

Memory IC Applications

• High-performance networking equipment requiring low-latency packet buffering
• Telecommunications infrastructure utilizing interleaved I/O architectures
• Industrial automation systems demanding reliable dual-port data exchange

Memory IC Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheets. Confirm package integrity and pin alignment prior to installation. Ensure supply chain sources provide valid traceability documentation. Validate that the specific suffix matches required voltage and temperature specifications. Review moisture sensitivity levels to determine proper handling and storage conditions during assembly.

Memory IC Selection Notes

Select this component for designs requiring independent port access without external arbitration logic. Consider the 208-CABGA footprint for board layout constraints. Evaluate power consumption requirements against the specified operating current limits. Ensure the host system supports the necessary clock frequency and voltage tolerances for stable operation.

Memory IC Part Context

This part belongs to the 70T3319 series of synchronous dual-port SRAMs from Renesas Electronics. The series is designed for applications needing high bandwidth and low latency. The BFGI8 suffix indicates specific packaging and environmental compliance attributes. These devices are commonly used in embedded systems requiring fast memory access.

Memory IC Replacement Considerations

Check for direct substitutes within the 70T3319 family such as the 70T3319S133BFI or 70T3319S133BCGI. Verify pin compatibility and electrical parameter equivalence before substitution. Note that some variants may have different package types or temperature ranges. Consult official discontinuation notices for availability status of potential replacements.
