Memory IC Overview

The Renesas 70T3599S133BC8 is a static random-access memory component featuring a 128K x 36 organization and 4.5 Mbit capacity. It operates as a synchronous dual-port RAM with parallel interface, supporting a clock frequency of 133 MHz and an access time of 4.2 ns. The device utilizes a 256-pin CABGA package (17x17 mm) and functions within a supply voltage range of 2.4V to 2.6V. It is designed for surface mount installation and supports industrial temperature ranges.

Memory IC Feature Summary

Supports simultaneous independent access to the same memory location by both ports
Features full synchronous operation on both ports for high-speed data handling
Includes selectable pipeline or flow-through output modes for flexible system integration

Memory IC Applications

High-performance networking equipment requiring low-latency data buffering
Telecommunications systems utilizing fast packet processing
Industrial automation controllers needing reliable dual-port memory

Memory IC Procurement Notes

This component is officially designated as End-of-Life (EOL). Manufacturers have issued discontinuance notifications indicating that production will cease. Current availability is restricted, and sourcing new units may be difficult. Engineers should verify stock status with authorized distributors and prepare for immediate migration to alternative components to ensure long-term supply chain stability.

Memory IC Selection Notes

Select this part only if legacy compatibility with existing 128K x 36 synchronous dual-port architectures is required. Verify that the 256-CABGA footprint matches the PCB design constraints. Ensure the 2.5V I/O voltage levels are compatible with the target system logic. Due to the EOL status, prioritize evaluation of replacement options that offer similar performance metrics and pin configurations.

Memory IC Part Context

The 70T3599S133BC8 belongs to the Renesas 70T3599 series of high-speed synchronous dual-port SRAMs. This family is engineered for applications demanding concurrent read/write operations without arbitration delays. The specific suffix indicates the 133 MHz speed grade and the 256-pin CABGA packaging option, distinguishing it from other variants in the lineup.
