ACE1502EMT8

Overview

The ACE1502EMT8 is a programmable single-chip integrated circuit from the ACEx family, designed for high-performance, low-power, and small-size applications. It features an 8-bit microcontroller 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/idle timer, and programmable undervoltage detection. Operating on a single supply voltage of 1.8V to 3.6V, it offers a typical instruction cycle time of 1µs with ±2% accuracy using its internal oscillator. It supports in-circuit programming and provides multiple package options including 8-pin SOIC.

Feature Summary

• Integrated 8-bit microcontroller core with substantial non-volatile memory resources for program storage and data retention.
• Built-in hardware bit encoder (HBC) specifically designed for software-programmable IR/RF data transmission formats.
• Comprehensive power management capabilities including HALT and IDLE modes for significant energy reduction.
• On-chip clock and reset functions minimize external component requirements while ensuring system stability.

Applications

• Low-power embedded systems requiring compact form factors
• IR and RF remote control devices utilizing hardware bit encoding
• Battery-operated consumer electronics needing extended standby times

Procurement Notes

Verify the specific suffix 'EMT8' against official Fairchild or ON Semiconductor documentation to confirm the exact package type (typically 8-pin TSSOP or similar) and temperature grade. Ensure compatibility with existing PCB footprints and programming interfaces. Confirm that the device meets all required environmental specifications for the intended application environment.

Selection Notes

Select this component when design constraints demand a balance between processing capability and minimal power consumption. It is suitable for applications where external oscillators or complex peripheral circuits must be avoided. Consider the available memory sizes and I/O configurations to ensure they meet the specific functional requirements of the target system.

Part Context

The ACE1502 belongs to the ACEx (Arithmetic Controller Engine) product family, which targets applications prioritizing efficiency and miniaturization. This family utilizes CMOS technology to achieve fully static operation. The series includes variants like ACE1001, ACE1101, and ACE1202, offering scalable memory and feature sets for different performance tiers within the same architectural framework.

Replacement Considerations

Check for direct substitutes within the ACEx family such as ACE1202 or ACE1101 if pinout and memory requirements align. Verify that any replacement maintains the same 8-bit architecture and EEPROM-based programming methodology to ensure software compatibility.
