ACE1001EN

Overview

The ACE1001EN is an 8-bit microcontroller from the ACEx family, designed for low-power applications. It features a fully static CMOS core with 1K bytes of code EEPROM, 64 bytes of data EEPROM, and 64 bytes of RAM. The device operates on a single supply voltage ranging from 2.2V to 5.5V and supports a maximum clock frequency of 4 MHz. It includes an on-chip oscillator, watchdog timer, and programmable undervoltage detection. The component is housed in an 8-pin SOIC package.

Feature Summary

• Integrated arithmetic controller engine with on-chip memory and peripherals
• Low power operation with HALT and IDLE modes
• On-chip oscillator eliminating external components
• Programmable undervoltage detection and watchdog timer

Applications

• Battery-powered consumer electronics
• Portable instrumentation
• Low-cost embedded control systems

Procurement Notes

Verify the specific suffix EN against official Fairchild documentation to confirm package type and temperature range. Ensure compliance with RoHS directives if required by your application standards. Cross-reference the datasheet revision date to confirm current manufacturing status and any potential obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when a small footprint and minimal external circuitry are required. The integrated oscillator and reset functions reduce bill of materials complexity. Consider the 8-bit architecture and limited RAM size for simple control tasks rather than complex processing requirements.

Part Context

This part belongs to the ACE1001 product family, which utilizes the ACEx (Arithmetic Controller Engine) architecture. The family focuses on providing high performance in a small package with low power consumption. The ACE1001EN variant specifically denotes the industrial temperature range and SOIC-8 packaging configuration within this series.

Replacement Considerations

Direct replacements may include other members of the ACE1001 family such as ACE1001M8 or ACE1001EM8, provided pin compatibility and electrical specifications match. Verify that alternative parts support the same voltage range and package dimensions.
