70T3539MS166BC

Memory IC Overview

The Renesas Electronics Corporation 70T3539MS166BCG is a synchronous dual-port static random-access memory (SRAM) device. It features an 18 Mbit storage capacity organized as 512K x 36 bits. The component supports a maximum clock frequency of 166 MHz with a typical access time of 3.6 ns. It operates within a supply voltage range of 2.4 V to 2.6 V and draws a maximum power current of 900 mA. The device utilizes a parallel interface and is housed in a 256-CABGA package measuring 17x17 mm. It functions reliably across an operating temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Synchronous dual-port architecture enabling simultaneous independent access to memory locations by two separate ports.
• Automatic power-down functionality controlled by chip enable signals to minimize standby power consumption.
• Support for burst data flow operations optimized for unidirectional or bidirectional applications.
• On-chip hardware support for semaphore signaling and interrupt flags to manage port contention.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in network processing equipment
• Data storage in industrial control systems requiring rapid write cycles

Memory IC Procurement Notes

Verify the exact suffix against official documentation, as 'BC' may denote specific packaging or temperature grades distinct from the verified 'BCG' variant. Confirm moisture sensitivity level requirements during handling. Check for RoHS3 compliance status. Ensure the supplier provides valid traceability documents. Validate that the delivered part matches the specified 256-CABGA footprint and pinout configuration.

Memory IC Selection Notes

Select this component when system design requires high-frequency synchronous operation at 166 MHz. The 36-bit data width suits applications needing wide bus interfaces without external multiplexing. Consider the 2.5V core voltage for low-power integration. Evaluate the 256-ball BGA package for space-constrained PCB layouts. Compare against slower variants if lower power consumption is prioritized over speed.

Memory IC Part Context

This device belongs to the 70T3539M series of high-speed synchronous dual-port SRAMs. The series is designed for applications demanding rapid consecutive write cycles and efficient data transfer. It shares architectural similarities with other members like the 70T3539MS133BCG, differing primarily in clock speed and access time specifications while maintaining compatible pinouts and functionality.

Memory IC Replacement Considerations

The 70T3539MS133BCG serves as a confirmed substitute within the same family. It offers identical pinout and functionality but operates at a reduced maximum clock frequency of 133 MHz with a 4.2 ns access time. Verify that the system timing constraints accommodate the slower performance before substitution.
