FAQ
What is the maximum operating frequency of the S9KEAZ64AMLHR?
The S9KEAZ64AMLHR operates at up to 48 MHz system clock frequency, derived from its internal FLL locked to either the 32.768 kHz crystal oscillator or the factory-trimmed 37.5 kHz internal reference. This frequency is fully supported across the –40°C to 125°C ambient temperature range and enables real-time execution of control loops with sub-microsecond jitter.
Does the S9KEAZ64AMLHR support CAN communication?
Yes, the S9KEAZ64AMLHR includes an MSCAN module compliant with ISO 11898-1, supporting CAN 2.0A/B protocols at data rates up to 1 Mbps. It features dedicated TX/RX pins (PTD0/PTD1), integrated bus-off recovery, and message buffering - making it suitable for vehicle network gateways and ECU integration without external CAN controllers.
What is the flash memory size and endurance rating for the S9KEAZ64AMLHR?
The S9KEAZ64AMLHR contains 64 KB of on-chip flash memory with program/erase endurance rated at 100,000 cycles. Flash erase times are 20.05 ms per sector and 100.18 ms for full chip erase, verified across the full operating voltage (2.7–5.5 V) and temperature (–40°C to 125°C) range per NXP KEA128 Sub-Family Data Sheet Rev. 7.
Can the S9KEAZ64AMLHR operate in ultra-low-power modes?
Yes, the S9KEAZ64AMLHR supports Stop mode with typical current consumption of 1.9 µA at 3 V and –40°C to 125°C. In this mode, the 1 kHz LPO remains active, allowing wake-up via RTC alarm, GPIO edge, or ADC hardware trigger - critical for battery-powered automotive modules requiring periodic sensor polling.
What debug interface does the S9KEAZ64AMLHR provide?
The S9KEAZ64AMLHR features a Serial Wire Debug (SWD) interface compliant with ARM CoreSight standards, supporting full-speed debugging, flash programming, and real-time trace at up to 24 MHz SWD_CLK. It requires only two pins (SWD_CLK and SWD_DIO) and is accessible through standard J-Link or CMSIS-DAP debug probes.
