70T3599S166BC8

Memory IC Overview

The Renesas Electronics Corporation 70T3599S166BC8 is a high-speed synchronous dual-port static random access memory (SRAM) IC. It features a storage capacity of 4.5 Mbit organized as 128K x 36 bits. The device supports parallel interface operations with a maximum clock frequency of 166 MHz and an access time of 3.6 ns. It operates within a supply voltage range of 2.4V to 2.6V and is housed in a 208-CABGA package measuring 15x15 mm. The component is designed for surface mount installation and functions within a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Provides simultaneous independent read/write access through two separate ports for concurrent data handling
• Utilizes synchronous logic controlled by a single clock signal to ensure precise timing alignment
• Integrates parity error detection capabilities on both port A and port B data lines

Memory IC Applications

• High-performance telecommunications systems requiring low-latency data buffering
• Network infrastructure equipment such as routers and switches
• Industrial automation controllers needing fast shared memory resources

Memory IC Procurement Notes

Verify the specific suffix BC8 against official Renesas documentation to confirm the exact package type and moisture sensitivity level. Confirm RoHS compliance status as historical records indicate non-compliance for this series. Check for End-of-Life notices or Product Change Notifications that may affect long-term availability and manufacturing continuity.

Memory IC Selection Notes

Select this component when a design requires dual-port architecture with synchronous operation at speeds up to 166 MHz. Ensure the system power supply can maintain the required 2.4V to 2.6V range for stable performance. Verify that the PCB layout accommodates the 208-CABGA footprint and meets thermal requirements for the commercial operating temperature range.

Memory IC Part Context

This part belongs to the 70T3599 family of high-speed synchronous dual-port SRAMs manufactured by Renesas Electronics. The family is characterized by its ability to support complex data processing tasks in networking and industrial applications. The 70T3599 variant specifically offers a 4.5 Mbit density, distinguishing it from lower-capacity models within the same technological lineage.

Memory IC Replacement Considerations

Consult official Renesas cross-reference guides for verified substitutes. Potential alternatives include other members of the 70T3599 family with compatible pinouts and electrical characteristics.
