Overview
The ATSAMHA1G17A-MZT-BVAO is an automotive-grade System-in-Package (SiP) integrating a 32-bit ARM Cortex-M0+ microcontroller, LIN transceiver, and voltage regulator. It features 128 kB of Flash program memory and operates with a maximum clock frequency of 48 MHz. The device supports a data bus width of 32 bits and includes 13 ADC channels with 12-bit resolution. It provides 32 I/O pins in a VQFN-48 package, functioning within a supply voltage range of 5 V to 28 V and operating temperatures from -40°C to +105°C.
Feature Summary
- Integrates MCU, LIN transceiver, and voltage regulator into a single system-in-package solution
- Automotive qualification compliant with AEC-Q100 standards for reliability
- Supports multiple communication interfaces including I2C, SPI, and UART
Applications
- Automotive body control modules
- LIN network node implementation
- Low-power automotive electronic systems
Procurement Notes
Verify the specific suffix BVAO against official Microchip documentation to confirm pinout and thermal characteristics. Ensure compatibility with existing PCB layouts due to the VQFN-48 package dimensions. Confirm that the integrated LIN transceiver meets the specific electrical requirements of the target vehicle network topology before finalizing component selection.
Selection Notes
Select this component when a combined MCU and LIN interface is required to reduce board space. The integrated voltage regulator simplifies power design for automotive environments. Consider the 128 kB memory capacity for complex application logic. Verify that the 48 MHz processing speed aligns with real-time control requirements for the intended automotive subsystem.
Part Context
This part belongs to the ATSAMHA1G series, designed specifically for low-power automotive applications. It combines functional safety considerations with cost-effective integration. The series targets manufacturers needing robust connectivity without separate transceiver components. It represents a consolidated approach to embedded control in modern vehicle architectures.
Replacement Considerations
Consult official substitution lists for compatible variants within the ATSAMHA1G family. Verify memory size differences if upgrading or downgrading storage requirements. Ensure pin compatibility when replacing with other packages in the same series.
