ACE1502EN14

Overview

The ACE1502EN14 is a programmable single-chip microcontroller from the ACE1502 product family, designed for high-performance and low-power applications. It features an 8-bit ACEx core with 2K bytes of code EEPROM, 64 bytes of data EEPROM, and 64 bytes of RAM. The device includes a 16-bit timer, watchdog, and programmable undervoltage detection. Operating on a single supply voltage between 1.8V and 3.6V, it offers instruction cycle times of 1µs with ±2% accuracy using its internal oscillator. The EN14 suffix indicates a 14-pin SOIC package with an extended operating temperature range of -40°C to +125°C.

Feature Summary

• Integrated hardware bit encoder (HBC) for software-programmable IR/RF data transmission simulation
• All eight general-purpose I/O pins support multi-input wake-up functionality from low-power modes
• On-chip oscillator eliminates external components while maintaining precise timing control
• Supports online programming of internal data EEPROM, code EEPROM, and initialization registers

Applications

• Low-power consumer electronics requiring small form factors
• IR/RF remote control systems utilizing hardware bit encoding
• Battery-operated devices needing extended data retention capabilities
• Systems requiring robust watchdog reset mechanisms for stability

Procurement Notes

Verify the specific suffix 'EN14' corresponds to the 14-pin SOIC package variant when sourcing. Confirm that the required operating temperature range aligns with the V-series specification (-40°C to +125°C), as standard E-series parts may be limited to commercial temperatures. Ensure compatibility with existing PCB footprints for the 14-lead Small Outline Integrated Circuit configuration before finalizing procurement orders.

Selection Notes

Select this component when design constraints demand a fully static CMOS microcontroller with integrated non-volatile memory. The ACE1502EN14 is suitable for applications prioritizing minimal external component count due to its built-in clock and reset functions. Consider the 14-pin package availability if more GPIO lines are necessary compared to the 8-pin alternative, while maintaining the same core processing capabilities and power management features.

Part Context
