FAQ
What is the maximum operating frequency of the S9KEAZN64ACLHR?
The S9KEAZN64ACLHR operates at a maximum core frequency of 48 MHz. This speed is achieved using the internal FLL (Fractional Loop Lock) with reference to the internal 4 MHz IRC oscillator or an external crystal. The 48 MHz clock supports real-time control loops with sub-10 µs interrupt latency and meets timing requirements for USB full-speed device operation without external clock sources.
Does the S9KEAZN64ACLHR include an integrated USB physical layer (PHY)?
Yes, the S9KEAZN64ACLHR includes a fully integrated USB 2.0 full-speed (12 Mbps) device controller with on-die PHY. This eliminates the need for external transceivers or termination resistors. The USB_DP pin features a built-in 1.5 kΩ pull-up resistor for device enumeration, reducing BOM count and PCB layout complexity in embedded USB applications.
What low-power modes are supported by the S9KEAZN64ACLHR?
The S9KEAZN64ACLHR supports multiple low-power modes including VLLS0 (Very-Low-Leakage Stop 0), VLLS1, and STOP. In VLLS0 mode, current consumption drops to ≤1.5 µA while retaining RAM content and enabling wake-up via GPIO, RTC alarm, or USB resume signaling - making it ideal for battery-powered industrial sensors requiring multi-year operation.
Can the S9KEAZN64ACLHR's ADC perform hardware averaging?
Yes, the S9KEAZN64ACLHR's 12-bit SAR ADC supports configurable hardware averaging across 4, 8, 16, or 32 samples per conversion. This feature improves effective resolution and reduces noise without CPU intervention, delivering stable readings from resistive temperature detectors (RTDs) or potentiometers in electrically noisy factory environments.
Is the S9KEAZN64ACLHR pin-compatible with other Kinetis E-series MCUs?
The S9KEAZN64ACLHR is pin-compatible with the S9KEAZ128ACLH (128 KB flash) in the same 64-pin LQFP package. Both share identical peripheral pin mappings, allowing hardware reuse across firmware variants. However, it is not pin-compatible with Kinetis KE02Z or KL series due to differing peripheral assignments and power pin configurations.
