ACE1001MT8X

Overview

The ACE1001MT8X is an 8-bit microcontroller from the ACEx family, fabricated using fully static CMOS technology. It integrates a 1K byte code EEPROM, 64 bytes of data EEPROM, and 64 bytes of RAM. The device features an on-chip oscillator requiring no external components, with an instruction cycle time of 1µs. It supports single supply operation within the 2.2V to 5.5V range and includes peripherals such as an 8-bit timer with PWM output, watchdog timer, and programmable undervoltage detection.

Feature Summary

• Integrated arithmetic controller engine with low power HALT and IDLE modes
• On-chip clock and reset functions eliminating need for external components
• Memory mapped I/O with software selectable push-pull or high impedance options

Applications

• Low power embedded control systems
• Battery operated devices requiring minimal active current
• Simple automation tasks utilizing PWM outputs

Procurement Notes

Verify the specific suffix MT8X against official Fairchild documentation to confirm package type and temperature rating. Ensure compliance requirements match project specifications as some variants may not be RoHS compliant. Confirm availability status as older component families may have limited production runs.

Selection Notes

Select this component when a small footprint 8-bit controller with integrated non-volatile memory is required. The absence of external clock components simplifies PCB layout. Consider the 64-byte RAM limit for complex algorithm implementation and verify that the 8-bit timer resolution meets timing precision needs.

Part Context

This part belongs to the ACE1001 product family designed for applications demanding high performance in a small size. The family utilizes CMOS technology to achieve low power consumption while maintaining functional integrity. It serves as a dedicated programmable monolithic integrated circuit for cost-sensitive embedded solutions.

Replacement Considerations

Check for direct pin-compatible substitutes within the same ACEx family. Verify if alternative packages like TSSOP are available for the same core functionality. Ensure any replacement maintains the 2.2V to 5.5V operating voltage range.
