DS9034PCI+

Overview

The DS9034PCI+ is a non-volatile timekeeping module manufactured by Analog Devices Inc./Maxim Integrated. It integrates SRAM with backup management capabilities within a 34-PowerCap™ module package. The device supports lithium cell battery backup to maintain data retention during power loss. It operates within a temperature range of 0°C to 70°C and is designed for surface-mount installation. This component serves as a compact solution for preserving critical system time and configuration data in embedded applications requiring reliable non-volatile memory.

Feature Summary

• Integrates non-volatile SRAM with dedicated backup management circuitry
• Utilizes a 34-PowerCap™ module form factor for space-efficient design
• Supports lithium cell battery backup for continuous operation during main power failure

Applications

• Real-time clock (RTC) systems requiring persistent time data
• Embedded controllers needing non-volatile configuration storage
• Industrial equipment with backup power requirements

Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm exact electrical characteristics and pinout compatibility. Ensure the selected variant matches the required operating temperature range and battery interface specifications for your target application environment.

Selection Notes

Select this component when a combined SRAM and timekeeping solution is required in a single surface-mount package. Consider the PowerCap module size constraints and ensure the host system provides appropriate voltage levels for the integrated backup management circuitry.

Part Context

This part belongs to the Maxim Integrated PowerCap family, which combines memory and backup management in a single module. These modules are designed to simplify PCB layout by integrating the backup battery interface directly with the memory controller, reducing component count and assembly complexity.

Replacement Considerations

Consult the official cross-reference list for direct replacements. Verify that any substitute maintains the 34-PowerCap™ footprint and compatible backup voltage thresholds.
