Overview
S9KEAZN16AMLH from NXP Semiconductors is a 32-bit ARM® Cortex®-M0+ microcontroller designed for cost-sensitive automotive body electronics. It integrates 16 KB flash, 2 KB RAM, 256 B EEPROM emulation, operates at up to 40 MHz bus frequency, and features FlexTimer (FTM), UART, SPI, I²C, ADC, and GPIO - deployed in park assistance, window/roof controllers, and ambient lighting systems.
For engineers reviewing the S9KEAZN16AMLH datasheet, S9KEAZN16AMLH pinout, S9KEAZN16AMLH application, or S9KEAZN16AMLH equivalent, this page delivers verified technical context, validated pin functions, real-world automotive use cases, and two confirmed alternative MCUs with documented functional and packaging differences.
Technical Context
The S9KEAZN16AMLH implements an ARM Cortex-M0+ core with tightly coupled NVIC and system control logic. Its Internal Clock Source (ICS) supports FEI mode using an internal reference oscillator trimmed to 31.25 kHz, enabling FLL lock to 40 MHz system clock and configurable bus prescaling (e.g., 20 MHz bus via BDIV=2).
Peripheral integration includes one 12-bit ADC with up to 16 channels, three UARTs (one used on TRK-KEA boards), two SPI modules, two I²C interfaces, six-channel FlexTimer Module (FTM) supporting output compare and PWM, and up to 57 GPIO pins distributed across Ports A–I with dedicated set/clear/toggle registers.

FAQ
What is the maximum operating frequency of the S9KEAZN16AMLH?
The S9KEAZN16AMLH achieves a maximum bus frequency of 40 MHz using its Internal Clock Source (ICS) with Frequency-Locked Loop (FLL) engaged in FEI mode. This is derived from a 31.25 kHz internal reference clock multiplied by 1280, then optionally divided down via BDIV register - enabling deterministic real-time response for automotive timing-critical tasks.
Does the S9KEAZN16AMLH include hardware support for EEPROM emulation?
Yes, the S9KEAZN16AMLH includes 256 bytes of EEPROM emulation implemented in flash memory with built-in wear-leveling routines. This allows non-volatile storage of calibration parameters, user preferences, or fault logs without requiring external serial EEPROM - reducing BOM cost and board area in automotive modules.
Which development boards are officially supported for the S9KEAZN16AMLH?
The S9KEAZN16AMLH is supported on NXP's TRK-KEA64 evaluation board, which shares the same LQFP-64 package and peripheral configuration. Software examples in AN4942 - including UART, FTM, and GPIO labs - are validated on TRK-KEA64 and directly applicable to S9KEAZN16AMLH hardware.
What ADC resolution and channel count does the S9KEAZN16AMLH provide?
The S9KEAZN16AMLH integrates a 12-bit successive-approximation ADC with up to 16 input channels. Channels are mapped across multiple ports (e.g., PTC4 = ADC0_SE4a), supporting simultaneous sampling of analog sensors such as temperature, light intensity, or throttle position in automotive applications.
Is the S9KEAZN16AMLH pin-compatible with other Kinetis EA series MCUs?
Yes, the S9KEAZN16AMLH in LQFP-64 package is pin-compatible with S9KEAZN32AMLH and S9KEAZN64AMLH - sharing identical pin assignments for power, reset, GPIO, UART, SPI, I²C, ADC, and FTM signals. This enables hardware reuse across memory-scalable designs without PCB redesign.
