FAQ
What is the maximum operating frequency of the S9KEAZN16AMLHR?
The S9KEAZN16AMLHR features an Arm® Cortex-M0+ core rated for up to 48 MHz operation, with bus frequency up to 24 MHz. This performance level is achieved using the internal FLL with factory-trimmed 37.5 kHz reference or external crystal/resonator sources, and is fully supported across its –40°C to 125°C operating range. The S9KEAZN16AMLHR maintains timing compliance under worst-case voltage (2.7 V) and temperature conditions per its datasheet specifications.
Does the S9KEAZN16AMLHR include a CAN controller?
Yes, the S9KEAZN16AMLHR integrates a fully compliant MSCAN module supporting CAN 2.0A/B protocols, including message buffering, error handling, and bit-rate configuration up to 1 Mbps. It requires only an external ISO 11898-2 transceiver and proper PCB layout (termination, common-mode filtering) to implement a robust automotive network node. The S9KEAZN16AMLHR's MSCAN is functionally identical to that found in higher-flash variants of the KEAZ family.
What package type and pin count does the S9KEAZN16AMLHR use?
The S9KEAZN16AMLHR uses a 64-pin LQFP package (10 mm × 10 mm) with exposed thermal pad, designated by "LH" in its part number suffix. This package matches the mechanical and thermal characteristics of other LH-series KEAZ devices, including thermal resistance (RθJA = 57°C/W on single-layer board) and moisture sensitivity level (MSL 3). Pin compatibility is maintained across all 64-pin KEAZ variants sharing the LH identifier.
How much flash and RAM memory does the S9KEAZN16AMLHR have?
The S9KEAZN16AMLHR contains 16 KB of on-chip flash memory and 2 KB of SRAM. These memory resources are mapped into the standard ARM Cortex-M0+ address space and support features including flash security protection, EEPROM emulation, and bit-band aliasing for atomic peripheral register access. The S9KEAZN16AMLHR's memory configuration is optimized for compact automotive firmware with real-time constraints and limited PCB area.
Is the S9KEAZN16AMLHR qualified for automotive applications?
Yes, the S9KEAZN16AMLHR is automotive-qualified per AEC-Q100 Grade 1 (–40°C to +125°C) and carries the "S" prefix indicating full automotive qualification. It undergoes rigorous stress testing for temperature cycling, humidity, ESD (±6 kV HBM), latch-up (±100 mA), and long-term reliability. The S9KEAZN16AMLHR is approved for use in engine control, transmission, braking, and body electronics systems where functional safety and extended lifetime are mandatory.
