7035L15PFG8

Memory IC Overview

The Renesas Electronics Corporation 7035L15PFG8 is a high-speed 8K x 18 Dual-Port Static RAM designed for standalone or master/slave configurations. It features true dual-port architecture allowing simultaneous reads of the same memory location, separate upper-byte and lower-byte control for multiplexed bus compatibility, and on-chip port arbitration logic with semaphore signaling support. The device operates fully asynchronously from either port and includes an automatic power-down feature controlled by Chip Enable (CE). It utilizes a single 5V (±10%) TTL-compatible power supply, offers battery backup operation with 2V data retention, and is available in a 100-pin TQFP package.

Memory IC Feature Summary

• True dual-port architecture enabling simultaneous independent access to shared memory locations without external arbitration logic
• Integrated hardware support for semaphore signaling and interrupt flags between ports for efficient multi-processor communication
• Automatic low standby power mode activation via Chip Enable signals to minimize energy consumption during idle states
• Separate byte control lines facilitating direct compatibility with multiplexed bus systems requiring distinct upper and lower byte management

Memory IC Applications

• Stand-alone 144K-bit dual-port memory modules in embedded systems
• Master/Slave dual-port SRAM combinations for 36-bit or wider word systems
• High-speed data buffering between asynchronous processors
• Multiprocessor systems requiring error-free full-speed operation without discrete logic

Memory IC Procurement Notes

Verify the specific suffix 'G8' against official Renesas documentation to confirm reel packaging and lead-free status. Ensure the selected variant matches the required temperature grade and voltage specifications for your application environment. Cross-reference the part number with current production status notices to avoid obsolete components. Confirm moisture sensitivity level requirements align with your assembly process capabilities.

Memory IC Selection Notes

Select this component when designing systems requiring simultaneous read access to identical memory addresses from two independent ports. Consider the 100-pin TQFP package dimensions for PCB layout constraints. Evaluate the need for battery backup functionality if non-volatile retention below 2V is critical. Assess whether the 5V supply requirement fits within your system's power distribution network before finalizing the design.

Memory IC Part Context

This dual-port SRAM belongs to a family of high-performance memory devices intended for complex computing architectures. It supports both standalone operation and cascaded master/slave configurations to expand data bus widths beyond 18 bits. The inclusion of on-chip arbitration reduces external component count compared to earlier generations requiring discrete logic for port management.
