7005S35G

Overview

The Renesas Electronics Corporation 7005S35G is a high-speed, asynchronous dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kbit organized as 8K x 8 words. The device features parallel interface access with a maximum access time of 35 ns. It operates on a single 5V power supply within a voltage range of 4.5 V to 5.5 V. The component is housed in a 68-pin PGA package and supports surface mount or through-hole installation styles depending on the specific variant configuration. It functions within an industrial temperature range of 0°C to +70°C.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent reads and writes from two separate ports without conflict.
• On-chip hardware support for semaphore signaling and port arbitration logic to manage data integrity between ports.
• Integrated interrupt flag functionality to signal status conditions such as busy states or write completion.
• Automatic power-down feature controlled by chip enable inputs to minimize standby power consumption.

Applications

• Stand-alone 64K-bit dual-port RAM systems
• Master/Slave dual-port configurations for 16-bit or wider word systems
• High-speed data buffering in asynchronous communication interfaces

Procurement Notes

Verify the exact package type and suffix against the manufacturer's current datasheet, as legacy part numbers may have multiple physical variants. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for any product change notices or end-of-life announcements that may affect long-term availability. Ensure the ordering quantity matches the standard factory packaging specifications provided by the distributor.

Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration logic. The 35 ns access speed suits moderate-to-high frequency asynchronous applications. Consider the PGA package constraints for PCB layout and thermal management. Compare against other 7005 series variants if different access times or package formats like PLCC or TQFP are needed for space-constrained designs.

Part Context

The 7005S35G belongs to the Renesas 7005 family of high-speed dual-port SRAMs. This family is designed for applications requiring independent port access to shared memory resources. The device replaces earlier generations of dual-port memory solutions by integrating control logic directly on-chip. It serves as a bridge between different system domains requiring fast, conflict-free data exchange.

Replacement Considerations

The IDT7005S35G is a documented alias for this component. Verify pin compatibility and electrical specifications before substituting with other 7005 series parts such as the 7005S25J8, noting differences in access time and package type.
