The S9KEAZ64AMLH is an automotive-qualified 32-bit microcontroller from NXP Semiconductors' Kinetis EA (KEA) series, built on an Arm Cortex-M0+ core operating at up to 48 MHz. This cost-optimized automotive MCU integrates 64KB of program flash, 8KB of SRAM, and a rich peripheral set that includes one MSCAN controller for CAN connectivity, three UARTs, two SPI modules, two I2C interfaces, a 16-channel 12-bit SAR ADC, dual analog comparators with 6-bit DAC, and FlexTimer/PWM resources for motor control and actuator drive. Operating across a wide 2.7V to 5.5V supply range and an ambient temperature span of -40°C to +125°C, the device is supplied in a 64-pin LQFP package measuring 10mm x 10mm, making it a dependable choice for body electronics, gateways, and industrial controllers requiring long-term supply and robust quality.
Applications
● Automotive body control modules, window lifters, seat positioning, and HVAC actuators.
● CAN network nodes, gateways, and diagnostic interfaces in vehicle architectures.
● Industrial motor control, BLDC drives, and lighting ballasts using FlexTimer/PWM and the automotive math library.
● Cost-sensitive white goods, power tools, and general embedded controllers needing 5V tolerance and harsh-environment reliability.
FAQs
Q: Is this MCU AEC-Q100 qualified? A: Yes, the S9 prefix denotes automotive qualification suitable for in-vehicle applications across -40°C to +125°C.
Q: What debug interface is supported? A: Serial Wire Debug (SWD) provides a two-pin debug and programming interface.
Q: Can S9KEAZ128AMLH replace it directly? A: It is the closest same-package memory upgrade (128KB flash, 16KB RAM) but requires pinout, linker, and programming tool verification before approval.
Alternative automotive MCU Models
● S9KEAZ128AMLH: The same 48MHz, 64-LQFP platform with doubled 128KB flash and 16KB RAM for bootloader and feature-rich firmware.
● S9KEAZN64AMLH: The CAN-less, 40MHz, 4KB-RAM sibling for cost-driven nodes not requiring in-vehicle networking.
● S9KEAZ64AMLHR: The tape-and-reel packaging variant of the identical silicon for automated SMT assembly lines.
● S9KEAZ64AVLHR: The -40°C to +105°C mid-temperature grade for less harsh under-hood-adjacent installations.
● S9KEAZ128AMLK: The 80-pin LQFP version with expanded GPIO for designs needing more I/O than the 64-pin package.
