Overview
The C9KEAZN8AMFK is a microcontroller unit belonging to the Kinetis KEA series, manufactured by NXP USA Inc. It features an ARM Cortex-M0+ core operating at a maximum frequency of 48MHz. The device integrates 8KB of flash memory and 1KB of RAM. It supports multiple communication interfaces including I2C, LINbus, SPI, and UART/USART. The component operates within a voltage range of 2.7V to 5.5V and is rated for temperatures between -40°C and 125°C. It is housed in a 24-QFN package with 22 available I/O pins.
Feature Summary
- Built on the Kinetis EA series architecture targeting low-end automotive body applications
- Scalable low-power design supported by a comprehensive ecosystem of software drivers and example codes
- Integrated analog-to-digital converters providing high-resolution sensing capabilities
Applications
- Low-end automotive body control modules
- Automotive lighting systems
- Door lock and window control units
- Seat adjustment controllers
Procurement Notes
Verify the specific suffix 'C' against official NXP documentation to confirm temperature grade or variant specifics, as standard listings often reference the S9KEAZN8AMFKR variant. Ensure the source document explicitly identifies the C9KEAZN8AMFK part number rather than assuming equivalence with other KEA family members. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards.
Selection Notes
Select this component when designing for cost-sensitive automotive body electronics requiring ARM Cortex-M0+ performance. Consider the 24-QFN package constraints and the 2.7V to 5.5V supply range for power budgeting. Evaluate the 8KB flash limit against application code size requirements before finalizing the selection for production designs.
Part Context
This microcontroller is part of the broader Kinetis KEA family, which is optimized for entry-level automotive applications. It shares architectural similarities with other KEA variants but offers specific memory and pin configurations tailored for basic body control tasks. The family is designed to provide a scalable path for manufacturers moving from simple logic to programmable control in vehicle subsystems.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided data. Designers should consult NXP's official cross-reference tools or contact technical support directly for verified alternatives to the C9KEAZN8AMFK.
