5962-3829409MZA

Memory IC Overview

The Renesas Electronics Corporation 5962-3829409MZA is an obsolete asynchronous static random-access memory (SRAM) component organized as 8K x 8 bits, providing a total storage capacity of 64 Kbit. It operates on a single 5V supply with a voltage range of 4.5V to 5.5V and features a maximum access time of 55 ns. The device utilizes fully static CMOS circuitry, eliminating the need for external clocks or periodic refreshing. It includes a reduced power standby mode and supports battery backup data retention at supply levels as low as 2V. All inputs and outputs are TTL-compatible, and the unit employs three-state outputs for bus interfacing.

Memory IC Feature Summary

• Fully static asynchronous architecture requiring no clock signals or refresh cycles
• TTL-compatible inputs and outputs with three-state capability
• Reduced power standby mode with battery backup data retention down to 2V

Memory IC Applications

• Military systems compliant with MIL-STD-883 Class B standards
• High-speed address and chip select buffering
• Battery-backed volatile memory storage in embedded designs

Memory IC Procurement Notes

This component is officially classified as obsolete by the manufacturer. Availability is restricted to existing stock held by authorized distributors or secondary market suppliers. Verification of part authenticity and physical condition is critical due to the end-of-life status. Buyers must confirm specific lot dates and packaging integrity before acquisition, as standard manufacturing support and new production runs are no longer active.

Memory IC Selection Notes

Designers should evaluate the 55 ns access speed against system timing requirements, noting that faster variants exist within the same family. The CDIP-28 package requires through-hole mounting, which may impact modern PCB layout strategies. Consider the thermal characteristics and power consumption in standby mode when integrating into battery-operated or high-density military applications where space and energy efficiency are constrained.

Memory IC Part Context

The 5962-38294 series represents a line of high-performance CMOS SRAMs produced using advanced technology. These devices are designed for demanding environments, offering robust performance across wide temperature ranges from -55°C to +125°C. The series simplifies system design by providing direct TTL compatibility and eliminating complex control logic associated with dynamic memories, making them suitable for reliable data storage in critical infrastructure.

Memory IC Replacement Considerations

Direct functional replacements include other suffixes within the 5962-38294 series, such as 5962-3829407MZA or 5962-3829413MZA, which share the same 8K x 8 organization and CDIP-28 package but may differ in access speed grades.
