Overview
The ATSAME51G19A-MFT is an ARM Cortex-M4F microcontroller from the Microchip ATSAME51 series, operating at a maximum clock frequency of 120 MHz. It features 512 kB of Flash program memory and 192 kB of SRAM data RAM within a 48-lead TQFN package. The device supports a supply voltage range of 1.71 V to 3.6 V and includes 37 I/O pins. Key peripherals include 24-channel 12-bit ADCs, 2-channel 12-bit DACs, and interfaces such as CAN, LIN, I2C, SPI, USART, and USB.
Feature Summary
- Integrated floating-point unit (FPU) for efficient mathematical processing
- Supports automotive reliability standards via AEC-Q100 qualification
- Includes comprehensive connectivity options with USB, CAN, and LIN controllers
Applications
- Automotive body electronics and control modules
- Industrial motor control systems
- Consumer devices requiring high-performance processing
Procurement Notes
Verify the specific suffix 'MFT' corresponds to the 48-TQFN package and extended temperature or commercial grade requirements. Confirm AEC-Q100 compliance if automotive application is intended. Check moisture sensitivity level handling during assembly. Ensure pinout compatibility with existing PCB layouts before finalizing procurement.
Selection Notes
Select this component when a balance of processing power and peripheral richness is needed in a compact footprint. The 120 MHz Cortex-M4F core suits applications requiring real-time control. Compare against ATSAMD51 series if automotive qualification is not required. Verify that the 37 available I/O pins meet system interface needs.
Part Context
This part belongs to the ATSAME51 family, designed for high-performance embedded applications. It shares architectural similarities with the ATSAMD51 but adds automotive-grade certification. The G19 variant specifically denotes the 512 kB Flash configuration within the 48-pin form factor.
Replacement Considerations
ATSAME51G19A-AU offers the same specifications in a TQFP package. ATSAMD51G19A-MU provides identical electrical characteristics without automotive qualification.
