Overview
The ACE1001EN is an 8-bit microcontroller from the ACEx family, designed for low-power applications. It features a 1K byte 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 with an operating temperature range of -40°C to +85°C. Key peripherals include an 8-bit timer with PWM output, watchdog timer, and programmable undervoltage detection. It utilizes fully static CMOS technology.
Feature Summary
- Arithmetic Controller Engine optimized for bit manipulation and arithmetic operations
- On-chip oscillator requiring no external components
- Programmable read and write disable functions for memory protection
- Multilevel Low Voltage Detection and Brown-out Reset
Applications
- Low power embedded systems
- Battery operated devices
- Small size microcontroller applications
Procurement Notes
Verify the specific suffix 'EN' against official datasheets to confirm the extended temperature grade (-40°C to +85°C) and package type (SOIC-8 or TSSOP-8). Ensure compatibility with the 2.2V to 5.5V operating voltage range. Confirm that the component meets the required environmental specifications for your application.
Selection Notes
Select this component when a dedicated, low-cost microcontroller for arithmetic and bit manipulation is needed. Consider the ACE1001EN for designs requiring minimal external components due to the integrated oscillator and reset circuits. Evaluate the HALT and IDLE power modes if energy efficiency is critical.
Part Context
The ACE1001 belongs to the ACEx (Arithmetic Controller Engine) product family developed by Fairchild Semiconductor, now part of onsemi. This family targets applications demanding high performance with low power consumption and small physical footprint. The architecture is based on a modified Harvard design suitable for efficient code execution.
Replacement Considerations
Check for updated part numbers within the ACE1001L or ACE1001 series. Verify pinout and electrical characteristics match before substitution. Consult official replacement guides for any obsolescence notices.
