It carries 128 KB of Flash and 16 KB of RAM, sized for firmware stacks running CAN and LIN communication alongside local sensor processing. The 2.7 V to 5.5 V supply range lets it run directly off an automotive battery rail without a separate regulator, saving board space and BOM cost in body-control modules, door ECUs, and seat controllers. ## 128 KB Flash and 16 KB RAM — firmware capacity and data buffer sizing The 128 KB Flash (128K x 8) provides room for application code, bootloader, and calibration tables typical of automotive body functions. The 16 KB RAM supports moderate-sized data buffers for CAN message queues and sensor data logging. If your application requires over-the-air firmware updates or large lookup tables, verify that the combined code and data footprint fits within these limits — this is the mid-range density tier of the KEA family. ## -40°C to 105°C operating range — under-hood and industrial environments Rated for -40°C to 105°C ambient, this MCU handles the thermal extremes found in automotive under-hood compartments, engine bays, and outdoor industrial enclosures. The temperature grade is a key differentiator from commercial-range parts that would fail in these environments. Ensure your PCB layout and thermal management keep the junction temperature within this envelope during sustained operation. ## Integrated CAN and LIN — protocol-level connectivity without external transceivers The S9KEAZ128AVLHR includes CANbus, LINbus, I²C, SPI, and UART/USART interfaces. For automotive body networks, the built-in CAN and LIN controllers handle the protocol layer directly; you still need external transceivers for the physical layer. ## 58 I/O in a 64-LQFP — pinout density for sensor and switch arrays With 58 general-purpose I/O pins in a 64-LQFP package (10x10 mm), this MCU offers enough GPIO to handle a matrix of switches, LED indicators, and sensor inputs typical of automotive body controllers. The LQFP footprint is hand-solderable and inspectable, which helps during prototyping and low-volume production. The 64-pin count is a common density point; board layouts for this package are widely available. ## Active lifecycle — no EOL risk for new designs The S9KEAZ128AVLHR carries an active lifecycle status. The ROHS3 compliance covers current regulatory requirements for most markets.","metaTitle":"NXP S9KEAZ128AVLHR Kinetis KEA MCU, 48 MHz ARM Cortex-M0+","metaDescription":"NXP S9KEAZ128AVLHR 32-bit MCU, ARM Cortex-M0+ at 48 MHz, 128 KB Flash, 16 KB RAM, CAN/LIN, -40 to 105°C, 64-LQFP.
