7035L15PF

Memory IC Overview

The 7035L15PF 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 with TTL-compatible I/O levels and supports battery backup for data retention down to 2V. The device features true dual-port architecture allowing simultaneous reads from the same location, separate upper-byte and lower-byte control for multiplexed bus compatibility, and on-chip hardware support for semaphore signaling and port arbitration. It includes an interrupt flag and automatic power-down mode controlled by Chip Enable.

Memory IC Feature Summary

• True dual-port architecture enables simultaneous independent access to memory locations from either port without external arbitration logic.
• Integrated hardware semaphore signaling and port arbitration logic facilitate direct communication between connected processors.
• Separate byte write controls allow flexible data handling for systems requiring multiplexed bus compatibility.
• Automatic low-power standby mode reduces consumption when chip enable signals are inactive.

Memory IC Applications

• Stand-alone high-speed dual-port memory modules
• Master/Slave dual-port configurations for 36-bit or wider word systems
• Multiprocessor systems requiring shared memory resources

Memory IC Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified suppliers. Confirm package integrity and lead condition prior to installation. Review the latest datasheet for any pinout revisions or environmental compliance updates. Ensure proper electrostatic discharge handling during storage and assembly processes.

Memory IC Selection Notes

Select this component for applications requiring full-speed asynchronous dual-port access without external logic overhead. Consider the 100-pin TQFP package constraints and industrial temperature range availability. Evaluate power requirements against the single 5V supply specification and verify compatibility with system voltage levels.
