• Includes hardware bit-coder logic optimized for block encryption
• Provides low power HALT and IDLE operating modes

Applications

• Remote keyless entry systems
• RF interface applications
• Low power embedded control circuits

Procurement Notes

Verify the specific suffix 'EMX' against official documentation to confirm the exact package type and temperature rating. Confirm that the component status aligns with current availability as older revisions may be discontinued. Ensure the ordering information matches the required voltage range and pin configuration for your design.

Selection Notes

Select this component for applications requiring small size and low power consumption. The ACEx architecture is suitable for bit manipulation and encryption tasks. Consider the available I/O options and memory constraints when designing the system architecture.

Part Context

The ACE1202 belongs to the ACEx (Arithmetic Controller Engine) product family designed by Fairchild Semiconductor, now part of onsemi. This family targets high-performance, low-power applications using dedicated programmable integrated circuits. The technology utilizes CMOS fabrication to achieve efficient operation in compact form factors.

Replacement Considerations

Check for updated part numbers within the ACE1202 series or other ACEx family members. Verify compatibility with existing firmware and peripheral configurations before substituting.
