7035L12PF8

Memory IC Overview

The 7035L12PF8 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 an interrupt flag. The device includes on-chip port arbitration logic and full hardware support for semaphore signaling between ports. It operates fully asynchronously from either port and supports battery backup with 2V data retention. Powered by a single 5V supply (±10%), it offers automatic power-down via Chip Enable inputs. Available in a 100-pin TQFP package, it supports industrial temperature ranges.

Memory IC Feature Summary

• True dual-port architecture enables simultaneous independent access to shared memory locations without external arbitration logic.
• Integrated hardware semaphore signaling and port arbitration facilitate efficient inter-processor communication.
• Separate byte control lines allow flexible multiplexed bus compatibility for system integration.

Memory IC Applications

• Standalone 144K-bit dual-port memory systems
• Master/Slave dual-port configurations for 36-bit or wider word systems
• Multiprocessor systems requiring low-latency shared data exchange

Memory IC Procurement Notes

Verify component authenticity through authorized Renesas distributors or direct manufacturer channels. Confirm package integrity and lead condition upon receipt. Check datasheet revisions for any pinout or electrical parameter updates. Ensure storage conditions comply with moisture sensitivity level requirements before soldering. Validate part marking against official Renesas identification standards.

Memory IC Selection Notes

Select this component when asynchronous dual-port access with integrated arbitration is required. Suitable for applications needing simultaneous read/write operations across two processors. Consider the 100-pin TQFP package for board space constraints. Verify voltage compatibility with 5V TTL logic levels. Evaluate power consumption requirements against the automatic power-down capabilities provided by chip enable controls.

Memory IC Part Context

The 7035 series represents Renesas' high-performance dual-port SRAM family. These devices are engineered for complex embedded systems requiring fast, conflict-free memory sharing. The 7035L12PF8 variant specifically targets 18-bit wide data paths. It integrates advanced control features to simplify system design compared to discrete logic solutions.
