7035S15PF

Memory IC Overview

The Renesas 7035S15PF is an asynchronous dual-port static RAM with a density of 144 kilobits, organized as 8K words by 18 bits. It operates on a single 5V power supply and features a 15 nanosecond access time. The device supports simultaneous independent reads from both ports and includes hardware semaphore signaling for port arbitration. It utilizes a 100-pin TQFP package and functions within the commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous independent access to memory locations
• Integrated hardware semaphore logic for automatic port arbitration and conflict resolution
• Separate upper-byte and lower-byte control signals for multiplexed bus compatibility
• Automatic low-power standby mode activated via Chip Enable input

Memory IC Applications

• High-speed data buffering in parallel processing systems
• Master/Slave memory configurations for wide-word architectures
• Real-time communication interface storage
• Industrial control system data logging

Memory IC Procurement Notes

Verify the specific suffix against official documentation to confirm voltage tolerance and temperature grade. Confirm RoHS compliance status and moisture sensitivity level requirements before integration. Ensure the selected package variant matches the target PCB footprint specifications exactly.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration logic. Verify that the 18-bit word width aligns with the system bus architecture. Confirm that the 5V supply requirement fits the available power rails and that the TQFP-100 package is suitable for the assembly process.

Memory IC Part Context

This part belongs to the Renesas 7035 series of high-speed dual-port SRAMs. These devices are designed to replace complex discrete logic solutions in multi-processor environments. The series provides a compact solution for applications requiring fast, contention-free memory sharing between two independent processors or controllers.

Memory IC Replacement Considerations

Direct replacements include variants such as the 7035L15PFG or 7035S20PF, provided they match the pinout and electrical characteristics. Verify that any substitute maintains the same 8K x 18 organization and 100-pin TQFP package to ensure mechanical compatibility.
