ACE1502EMX

Overview

The ACE1502EMX is a CMOS-based, fully static programmable microcontroller from the ACEx family. It integrates an 8-bit core with 2K bytes of code EEPROM, 64 bytes of data EEPROM, and 64 bytes of RAM. Key peripherals include a 16-bit timer, watchdog, and programmable undervoltage detector. Operating on a single supply of 1.8V to 3.6V, it features an internal oscillator with ±2% accuracy and instruction cycle times of 1µs. The device supports low-power HALT (100nA at 2.7V) and IDLE modes, ensuring extended battery life in compact designs.

Feature Summary

• Integrated hardware bit encoder for software-programmable IR/RF transmission formats
• All eight general-purpose I/O pins support multi-input wake-up functionality
• Supports in-circuit programming of code EEPROM, data EEPROM, and initialization registers
• On-chip clock and reset circuitry minimizes external component requirements

Applications

• Low power consumer electronics
• IR and RF remote control systems
• Battery-operated portable devices
• Small size embedded control applications

Procurement Notes

Verify the specific suffix 'EMX' against official Fairchild or ON Semiconductor documentation to confirm package type and temperature range. Ensure compatibility with existing PCB footprints for SOIC-8 or TSSOP-8 configurations. Confirm that the intended application environment falls within the specified operating voltage and temperature limits defined in the datasheet.

Selection Notes

Select this component when design constraints require minimal external components due to integrated oscillators and regulators. It is suitable for applications needing flexible memory management via in-circuit programming. Consider the trade-off between the 8-bit architecture's simplicity and the specific peripheral needs like the hardware bit encoder for communication protocols.

Part Context

This part belongs to the ACEx product family, designed for arithmetic controller engine tasks. The family includes variants like ACE1001, ACE1101, and ACE1202, sharing similar architectural foundations but differing in memory sizes and pin counts. The ACE1502 represents a higher-capacity option within this low-power series.

Replacement Considerations

Check for direct substitutes within the ACEx family such as ACE1202 or ACE1101 if memory requirements differ. Verify pinout compatibility before substituting with other 8-bit MCUs from different manufacturers, as peripheral configurations may vary significantly.
