ATSAMC20G15A-AUT

Overview

The ATSAMC20G15A-AUT is a 32-bit microcontroller based on the ARM Cortex-M0+ core, operating at a maximum frequency of 48 MHz. It features 32 KB of in-system programmable Flash memory and 4 KB of SRAM. The device supports a supply voltage range of 2.7 V to 5.5 V and includes an internal oscillator. It provides 14 channels of 12-bit analog-to-digital conversion and one 10-bit digital-to-analog converter. Connectivity options include I2C, SPI, UART/USART, LIN, and PMBus interfaces. The unit is housed in a 48-TQFP package with 38 available I/O pins.

Feature Summary

• Supports 5V operation within a wide voltage range for robust system integration
• Integrates CAN-FD capability for high-speed automotive communication networks
• Includes Programmable Touch Sense (PTC) controller for capacitive sensing applications
• Features advanced analog peripherals including multiple ADC channels and a DAC

Applications

• Automotive body control modules requiring CAN-FD support
• Industrial controllers utilizing LIN bus communication
• Consumer devices needing capacitive touch interface capabilities
• General-purpose embedded systems requiring 5V tolerance

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm automotive qualification status. Ensure the ordering part number matches the required package variant and temperature rating. Cross-reference the datasheet revision date to validate current manufacturing status and any potential design changes or errata updates before finalizing procurement specifications.

Selection Notes

Select this component when 5V input compatibility is required alongside CAN-FD and LIN bus connectivity. The inclusion of a PTC controller makes it suitable for touch-sensitive user interfaces without external sensors. Compare memory sizes against application requirements, noting the 32 KB Flash limit. Verify that the 48 MHz clock speed meets real-time processing needs for the intended control logic.

Part Context

This device belongs to the SAM C20 family, designed for cost-effective 32-bit microcontroller applications. It extends the standard SAM D series by adding automotive-grade features such as CAN-FD and enhanced analog performance. The family targets industries requiring reliable communication protocols and robust power management in compact packages.

Replacement Considerations

ATSAMD20G15A-AUT lacks CAN-FD and 5V support; verify functional equivalence if substituting. ATSAMC20G16A-AUT offers increased memory but similar peripheral sets.
