7035S12PF8

Memory IC Overview

The 7035S12PF8 is a high-speed 8K x 18 Dual-Port Static RAM designed for stand-alone or MASTER/SLAVE configurations. It features true dual-port architecture allowing simultaneous reads of the same memory location, with separate upper-byte and lower-byte control for multiplexed bus compatibility. The device includes on-chip port arbitration logic, semaphore signaling support, and an automatic power-down feature controlled by Chip Enable inputs. It operates asynchronously from either port and supports battery backup operation with data retention down to 2V.

Memory IC Feature Summary

• True dual-port architecture enables simultaneous independent access to shared memory locations without external arbitration logic.
• Integrated hardware support for semaphore signaling and interrupt flags facilitates efficient inter-port communication.
• Automatic power-down mode reduces standby current when chip enable inputs are deactivated.
• Separate byte controls allow flexible compatibility with multiplexed bus systems.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Master/slave memory expansion for wide-word processing systems
• Real-time data logging in industrial control applications

Memory IC Procurement Notes

Verify component authenticity through authorized Renesas distributors. Confirm package integrity and moisture sensitivity level handling requirements prior to assembly. Check for specific suffix variations that may indicate different temperature grades or packaging formats. Ensure compliance with RoHS directives if required for the target application environment.

Memory IC Selection Notes

Select this component for applications requiring concurrent access to identical memory addresses by two independent processors. Consider the 100-pin TQFP package constraints and asynchronous interface timing requirements. Evaluate power consumption needs against the automatic power-down capabilities provided by the chip enable controls.

Memory IC Part Context

This part belongs to the 7035 series of dual-port SRAMs, which are optimized for high-performance data storage where simultaneous read/write operations are critical. The series supports various access times and voltage levels to accommodate different system architectures and performance thresholds.

Memory IC Replacement Considerations

Consult official Renesas documentation for verified cross-reference parts. Verify pinout compatibility and electrical specifications before substituting. Ensure functional equivalence in semaphore and arbitration logic if replacing in complex multi-port systems.
