7035L15PFG

Memory IC Overview

The 7035L15PFG is an asynchronous dual-port static random-access memory 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 component is housed in a 100-pin thin quad flat package and supports industrial temperature ranges.

Memory IC Feature Summary

• True dual-port architecture enables simultaneous independent reads from the same memory location by both ports.
• Integrated hardware semaphore signaling and port arbitration logic facilitate direct communication between connected processors.
• Separate upper-byte and lower-byte control lines allow compatibility with multiplexed bus systems.
• Automatic power-down mode reduces standby current when chip enable signals are inactive.

Memory IC Applications

• Stand-alone high-speed memory modules
• Master/slave configurations for 36-bit or wider data systems
• Multiprocessor systems requiring shared data exchange

Memory IC Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and temperature grade. Ensure the design accounts for the 5V supply requirement and TTL-compatible interface levels. Confirm availability status as manufacturing lifecycles may change.

Memory IC Selection Notes

Select this component for applications requiring true simultaneous access to shared memory without external arbitration logic. The integrated semaphore support simplifies multi-processor synchronization. Verify that the 100-pin TQFP footprint fits the target board layout constraints.

Memory IC Part Context

This device belongs to the 7035 series of dual-port SRAMs designed for high-performance data sharing. It eliminates the need for discrete logic in master/slave setups, offering full-speed operation for wide-word systems while maintaining low power consumption through automatic standby modes.
