70T659S12BCI

Memory IC Overview

The Renesas Electronics Corporation 70T659S12BCI is an asynchronous dual-port static random-access memory (SRAM) device. It features a storage organization of 128K words by 36 bits, providing a total capacity of 4.5 Mbit. The component operates with a supply voltage range of 2.4 V to 2.6 V and supports a maximum access time of 12 ns. It utilizes a parallel interface and is housed in a 256-pin CABGA package. The device is rated for industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

Supports independent read and write operations on both ports simultaneously without conflict
Includes automatic power-down functionality controlled by chip enable inputs to minimize standby current
Designed for high-speed data buffering and protocol conversion applications

Memory IC Applications

Network router and switch memory buffers
Telecommunications equipment data processing
Industrial control system data logging

Memory IC Procurement Notes

Verify the specific suffix 'BCI' against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS status as non-compliant based on available distributor data. Check for active product discontinuance notifications or end-of-life notices prior to finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 36-bit wide data path is required for dual-port synchronization. Ensure the design accommodates the 2.5V nominal supply voltage and the thermal requirements of the 256-pin CABGA package. Verify that the 12 ns access speed meets the system timing constraints for the intended asynchronous interface.

Memory IC Part Context

This part belongs to the Renesas 70T659 series of dual-port SRAMs. It shares architectural similarities with other members of the family but differs in density and package options. The 70T659 series is engineered for high-performance networking and telecommunications infrastructure where low-latency data handling is critical.
