29103BRA

Overview

The Intersil 29103BRA is a volatile Static Random Access Memory (SRAM) integrated circuit. It provides a total memory capacity of 16Kbits, organized in a 16K x 1 configuration. The device utilizes a parallel interface for data access and features an access time of 85 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Provides non-volatile storage capability with fast parallel access times
• Designed for operation across wide industrial temperature extremes
• Compatible with standard 5V logic supply voltages

Applications

• Industrial control systems requiring reliable data retention
• Embedded applications needing fast local memory access
• Military or aerospace electronic equipment operating in harsh environments

Procurement Notes

Verify the specific manufacturer origin, as this component was produced by Xicor, which became part of Intersil and subsequently Renesas. Confirm package integrity and pinout compatibility before integration. Check current availability status as legacy components may have limited stock or obsolescence risks.

Selection Notes

Select this component when a single-bit wide SRAM architecture is required for simple data buffering or register storage. Ensure the system design accommodates the 85ns access speed and 5V logic levels. Consider the physical package constraints and thermal management requirements for the specified temperature range during PCB layout.

Part Context

This part belongs to the legacy Intersil/Xicor SRAM portfolio. It represents a specialized memory solution for niche industrial and military applications where specific timing and voltage characteristics are critical. The component reflects older semiconductor manufacturing technologies compared to modern high-density memories.

Replacement Considerations

Direct substitutes include other 16Kx1 SRAM devices with similar 85ns access times and 5V operation. Verify pin-to-pin compatibility and electrical specifications against alternatives from manufacturers such as Cypress, AMD, or Micron that offer equivalent legacy memory solutions.
