5962-8855204UA

Memory IC Overview

The 5962-8855204UA is a high-speed asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a 256K-bit capacity organized as 32K words by 8 bits. The device operates with a single 5.0V power supply and utilizes a parallel interface. Key electrical specifications include access times of 45ns, 55ns, or 70ns depending on the speed grade. It supports low-power operation with a reduced standby mode and offers battery backup capability with data retention down to 2V. The component is housed in a 28-pin Ceramic Dual In-Line Package (CDIP).

Memory IC Feature Summary

• Supports low-power operation with reduced standby mode for system-level power savings.
• Enables battery backup operation with data retention at voltages as low as 2V.
• Features high-speed asynchronous access with direct input/output compatibility.

Memory IC Applications

• Embedded systems requiring non-volatile-like reliability with volatile speed.
• Industrial control applications needing robust memory solutions.
• IoT devices utilizing battery-backed memory architectures.
• Consumer electronics requiring high-speed data buffering.

Memory IC Procurement Notes

Verify the specific speed grade (45ns, 55ns, or 70ns) required for your design, as this affects performance. Confirm package integrity for the 28-CDIP form factor. Check current availability status as the part may be obsolete or limited in stock. Ensure voltage levels match the 5.0V requirement and battery backup needs are addressed if applicable.

Memory IC Selection Notes

Select this component when a high-speed SRAM with battery backup capability is needed. Consider the 28-CDIP package constraints for PCB layout. Evaluate the specific access time requirements against available speed grades. Ensure the system can support the 5.0V supply and 2V retention threshold for battery modes.

Memory IC Part Context

This part belongs to the 5962-88552 family, also known as the 71256 SRAM series. It is designed for applications demanding fast read/write cycles and low power consumption. The military-grade or industrial-grade variants often use this numbering convention. It serves as a reliable memory solution for critical data storage in harsh environments.

Memory IC Replacement Considerations

Check for compatible parts within the 5962-88552 series with different speed grades. Verify pinout compatibility for the 28-CDIP package. Ensure voltage and power specifications match exactly. Consult manufacturer documentation for direct substitutes or newer generations with similar functionality.
