70T3399S166BC8

Memory IC Overview

The Renesas Electronics Corporation 70T3399S166BC8 is a synchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 2 megabits, organized as 128K words by 18 bits per word. The device operates with a parallel interface and supports a maximum clock frequency of 166 MHz, achieving an access time of 3.6 nanoseconds. It requires a supply voltage range of 2.4V to 2.6V and functions within an ambient temperature range of 0°C to 70°C. The component is housed in a 256-lead CABGA package measuring 17x17 mm.

Memory IC Feature Summary

• Supports simultaneous independent access to the same memory location from two separate ports
• Features full synchronous operation on both ports for high-speed data handling
• Utilizes a parallel interface architecture optimized for burst data flow applications

Memory IC Applications

• High-performance networking equipment requiring low-latency buffering
• Telecommunications systems utilizing packet switching and routing
• Industrial automation controllers needing rapid data acquisition
• Test and measurement instruments requiring fast memory cycles

Memory IC Procurement Notes

Verify current availability status as this component has been officially discontinued by the manufacturer. Confirm that the specific suffix matches the required pinout and electrical specifications. Check for RoHS compliance requirements against the non-compliant status indicated in public records. Ensure replacement strategies are established due to end-of-life constraints.

Memory IC Selection Notes

Select this part when a synchronous dual-port SRAM with 2Mb density and 166 MHz performance is required. Ensure the design accommodates the 2.4V to 2.6V supply voltage range. Verify that the 256-CABGA package dimensions fit the target PCB layout. Consider the industrial temperature range limits if operating conditions exceed 70°C.

Memory IC Part Context

This component belongs to the 70T3399 series of synchronous dual-port RAMs from Renesas. It shares architectural similarities with other members like the 70T3599 but differs in density and organization. The series is designed for applications demanding high throughput and simultaneous port access. It represents a legacy product line now marked for discontinuation.
