A3024SO20A+

Overview

The A3024SO20A+ is a very low power 8-bit real-time clock (RTC) IC featuring a 32 kHz crystal oscillator and digital trimming capabilities. It integrates user-accessible RAM for data storage and operates within a supply voltage range of 2V to 5.5V. The device supports industrial temperature ranges from -40°C to +85°C. Packaged in a 20-SOIC format, it provides precise timekeeping functions suitable for applications requiring accurate calendar and clock tracking with minimal power consumption.

Feature Summary

• Integrates digital trimming for enhanced accuracy without external calibration components
• Includes dedicated user RAM for storing system-specific data alongside timekeeping functions
• Operates reliably across wide industrial temperature and voltage ranges

Applications

• Industrial control systems requiring precise time synchronization
• Computing equipment needing reliable calendar tracking
• Communications infrastructure devices demanding low-power RTC solutions

Procurement Notes

Verify the specific ordering suffix and package variant against the official EM Microelectronic datasheet to ensure compatibility with design requirements. Confirm that the RoHS status and lead-free specifications meet regulatory standards for the target market. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components during procurement.

Selection Notes

Select this component when an 8-bit RTC interface is sufficient for the application's timekeeping needs. Consider the 20-SOIC package dimensions for PCB layout constraints. Ensure the system voltage falls within the 2V to 5.5V operating range. Evaluate the need for integrated user RAM versus external memory solutions before finalizing the design choice.

Part Context

This part belongs to EM Microelectronic's portfolio of ultra-low-voltage watchdog and timing integrated circuits. The A3024 series focuses on providing efficient timekeeping solutions for embedded systems. It complements other products like watchdog ICs by offering complementary functionality for systems requiring both monitoring and precise temporal reference.

Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer's lineup. Verify if alternative RTC ICs offer similar voltage ranges and package styles. Ensure any replacement maintains the required digital trimming features and RAM capacity for data retention.
