C9KEAZN64AMLHR

Overview

The C9KEAZN64AMLHR is a 32-bit microcontroller from the NXP Kinetis KEA series, featuring an ARM Cortex-M0+ core. It integrates 64 kB of Flash memory and 16 kB of RAM, operating at a maximum clock frequency of 48 MHz. The device supports a supply voltage range of 2.7 V to 5.5 V and includes a 16-channel 12-bit SAR ADC with internal reference. Communication interfaces include two SPI modules, three UARTs, two I2C modules, and one CAN module. It is housed in a 64-pin LQFP package and certified to AEC-Q100 standards for automotive applications.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 qualification standards
• Integrated sensorless BLDC motor control capabilities via FlexTimer/PWM modules
• Low-power management with run, wait, and stop modes supported by PMC
• High-precision analog conversion using a 12-bit SAR ADC with hardware triggers

Applications

• Body electronics systems in automotive environments
• Sensorless brushless DC (BLDC) motor control applications
• Industrial control systems requiring robust communication interfaces
• General-purpose embedded controllers in automotive body applications

Procurement Notes

Verify the specific suffix 'H' indicates tape and reel packaging configuration when sourcing. Confirm that the component meets AEC-Q100 Grade 1 or 2 requirements based on the target temperature range. Ensure compatibility with existing design tools and software drivers provided for the Kinetis KEA family before finalizing procurement plans.

Selection Notes

Select this model when automotive certification is mandatory for body electronics or motor control projects. The 64 kB Flash size suits applications requiring moderate code storage without external memory. The inclusion of a CAN interface makes it suitable for networked vehicle subsystems. Compare against lower-capacity KEA variants if cost reduction is prioritized over peripheral count.

Part Context

This component belongs to the NXP Kinetis KEA family, designed specifically for automotive body applications. It shares architectural similarities with other KEA devices but offers distinct memory and pin configurations. The family emphasizes low power consumption and high integration for cost-sensitive automotive markets.

Replacement Considerations

S9KEAZN64AMLHR is a parameter-equivalent alternative within the same series. Verify package compatibility and suffix differences before substitution.
