7050S35PQF

Memory IC Overview

The 7050S35PQF is a four-port static random access memory (SRAM) device manufactured by Renesas Electronics. It provides a storage capacity of 1K x 8 bits, totaling 8 kilobits. The component features asynchronous operation with a maximum access time of 35 nanoseconds. It utilizes a parallel interface and operates on a single 5V power supply within the range of 4.5V to 5.5V. The device is housed in a 108-pin PGA package and supports commercial operating temperatures from 0°C to +70°C.

Memory IC Feature Summary

• Supports simultaneous independent access to the same memory location from all four ports without conflict.
• Includes on-chip hardware port arbitration logic for automatic semaphore signaling between ports.
• Features separate BUSY inputs to control write-inhibit status for each individual port.

Memory IC Applications

• Systems requiring concurrent data access from multiple processors or controllers.
• High-speed data buffering applications involving parallel processing architectures.
• Embedded systems utilizing true four-port memory cells for complex inter-process communication.

Memory IC Procurement Notes

Verify the current lifecycle status before procurement as this component may be discontinued. Confirm that the 108-pin PGA package matches your board design constraints. Ensure voltage levels align with the specified 5V requirement. Check for available replacement alternatives if new designs are required.

Memory IC Selection Notes

Select this component when true four-port simultaneous access is necessary rather than multiplexed dual-port solutions. Consider the 108-pin PGA package size against available PCB real estate. Evaluate the 35ns access speed against system timing requirements. Verify compatibility with existing TTL-compatible logic levels.

Memory IC Part Context

This part belongs to the 7050 series of four-port SRAMs designed for high-performance multi-processor environments. It offers greater concurrency than standard dual-port memories. The series supports battery backup operations for data retention. It is suitable for applications demanding low-latency shared memory access.

Memory IC Replacement Considerations

Consult official documentation for direct pin-compatible substitutes. The 7052 series serves as a higher-density alternative with similar functionality. Verify package dimensions and electrical specifications before substituting components.
