Overview
The ATSAMHA1G16A-MBT-BVAO is a System in Package (SiP) microcontroller integrating an ARM Cortex-M0 core, LIN transceiver, and voltage regulator. It features 64 kB of program memory and 8 kB of SRAM within a VQFN-48 package. The device supports a maximum clock frequency of 48 MHz with 32 I/O lines. It includes a 12-bit ADC and a 10-bit DAC. Operating voltages range from 5 V to 28 V, with an analog supply of 3.3 V. It meets AEC-Q100 automotive qualification standards and functions between -40°C and +105°C.
Feature Summary
- Integrates MCU, LIN transceiver, and voltage regulator into a single SiP solution
- Automotive qualified under AEC-Q100 standards for industrial reliability
- Supports high-voltage operation up to 28 V for direct bus connectivity
Applications
- Automotive Local Interconnect Network (LIN) node implementation
- Vehicle body control modules requiring integrated power management
- Industrial sensor interfaces operating in harsh thermal environments
Procurement Notes
Verify the specific suffix BVAO against the manufacturer's current datasheet to confirm pinout and packaging details. Confirm AEC-Q100 compliance status for your specific application requirements. Check for any recent obsolescence notices or lifecycle changes directly from Microchip Technology before finalizing procurement plans.
Selection Notes
Select this component when a combined MCU and LIN transceiver is required to reduce board space. The integrated voltage regulator simplifies power design for 5V to 28V systems. Ensure the 64 kB flash and 8 kB RAM meet the firmware storage needs. Verify that the VQFN-48 package fits the available PCB footprint constraints.
Part Context
This part belongs to the SAM HA1G series, designed specifically for automotive applications. It combines processing capabilities with communication interfaces in a compact form factor. The series targets cost-sensitive and space-constrained vehicle networks where integration reduces overall system complexity and component count.
Replacement Considerations
Consult Microchip documentation for direct cross-references. Verify pin compatibility and electrical specifications if substituting with other SAM HA1G variants.
