5962-8861009ZA

Memory IC Overview

The Renesas Electronics Corporation 5962-8861009ZA is a high-speed, military-grade dual-port static random access memory (SRAM) with a density of 32 kbit organized as 2k x 16 bits. It operates on a single 5V power supply and supports asynchronous interface protocols. The device features true dual-ported memory cells allowing simultaneous independent access to the same memory location from two ports. It includes versatile write control for byte-level operations and supports battery backup operation down to 2V for data retention. The component complies with MIL-PRF-38535 QML standards and is available in a 68-pin ceramic package.

Memory IC Feature Summary

• True dual-ported memory architecture enabling simultaneous access to identical memory locations without discrete logic arbitration
• Versatile write control supporting separate management of lower and upper bytes for each port
• Asynchronous operation from either port with full compatibility for TTL-compatible single 5V power supplies
• Battery backup capability ensuring data retention at voltages as low as 2V

Memory IC Applications

• Military-grade embedded systems requiring high-reliability memory
• High-speed data acquisition systems needing concurrent read/write access
• Avionics and aerospace applications compliant with MIL-PRF-38535 standards
• Industrial control systems utilizing master/slave dual-port RAM configurations

Memory IC Procurement Notes

Verify the specific suffix '09ZA' against official Renesas documentation to confirm exact screening levels, temperature range extensions, or packaging variations. Ensure compliance with current environmental directives such as RoHS if required by the application. Confirm availability status as military-grade components may have limited production runs or long lead times. Validate that the 68-pin PGA package dimensions match the target PCB footprint requirements.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is critical for system performance. It is suitable for designs requiring robust data integrity in harsh environments due to its military-grade qualification. Consider the 68-pin ceramic package constraints for thermal management and mechanical mounting. Evaluate the need for external arbitration logic; this part eliminates it through internal slave-on-chip port arbitration.

Memory IC Part Context

This part belongs to the 5962-88610 series of dual-port SRAMs manufactured by Renesas Electronics. These devices are designed for applications demanding high-speed, error-free operation without additional discrete logic. The series is characterized by its CMOS technology and compatibility with standard 5V logic families, making it a staple in legacy and specialized military electronic architectures.

Memory IC Replacement Considerations

Direct replacements must match the 2k x 16 organization, 68-pin PGA package, and MIL-PRF-38535 qualification. Verify pinout compatibility and electrical specifications, particularly access time and power supply requirements. Cross-reference with other 5962-series dual-port SRAMs from qualified manufacturers.
