DS9034PC+

Overview

The DS9034PC+ is a PowerCap module integrating nonvolatile SRAM, a real-time clock, crystal oscillator, and lithium battery. It operates at 3 V with a 2-pin surface-mount package. The commercial grade supports 0°C to +70°C.

Feature Summary

• Integrates nonvolatile static RAM, real-time clock, crystal, power-fail control circuit, and lithium energy source in a single surface-mountable PowerCap module.
• Features totally nonvolatile operation with over 10 years of data retention in the absence of power.
• Includes low-battery-voltage level indicator flag and power-fail write protection for system reliability.

Applications

• Battery-backed memory systems requiring long-term data retention
• Real-time clock applications needing Y2K compliance
• Embedded controllers requiring integrated timekeeping and storage

Procurement Notes

Verify component authenticity through authorized channels. Confirm lead times due to potential supply constraints. Check RoHS compliance status as indicated by datasheet revisions. Ensure proper handling procedures for lithium-integrated modules during assembly.

Selection Notes

Select this module for applications requiring compact integration of RTC and NVRAM. Consider thermal limits when designing enclosures. Verify voltage compatibility with host system. Evaluate space constraints against module dimensions.

Part Context

Part of Maxim Integrated's PowerCap family offering density upgrades and surface mount assembly options. Designed for direct connection to containing batteries and crystals without discrete components.

Replacement Considerations

Check pin-for-pin compatibility with other densities of DS174XP series. Verify functional equivalence for RTC and NVRAM requirements before substitution.
