ATSAMC20E17A-MUTS2

Overview

The ATSAMC20E17A-MUTS2 is an ARM microcontroller from the Microchip SAMC20 series, featuring an ARM Cortex-M0+ core. It integrates 128 kB of Flash program memory and 16 kB of SRAM data RAM within a VQFN-32 package. The device supports a maximum clock frequency of 48 MHz and operates on a supply voltage range of 2.7 V to 5.5 V. It includes a 12-bit ADC with 10 channels and provides 26 general-purpose I/O pins. Communication interfaces include CAN, I2C, RS-485, SPI, and UART. The component is qualified for automotive applications under AEC-Q100 standards and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Automotive-grade reliability certified by AEC-Q100 qualification standards
• Integrated high-accuracy RC48 oscillator for precise timing without external components
• Supports LIN bus communication protocols alongside standard serial interfaces
• Includes built-in EEPROM for non-volatile data storage

Applications

• Automotive body control modules requiring robust communication
• Industrial sensor nodes utilizing LIN or RS-485 networks
• Low-power embedded controllers in consumer electronics
• Smart metering systems with analog input requirements

Procurement Notes

Verify the specific suffix 'MUTS2' confirms the VQFN-32 package and tape-and-reel shipping format. Ensure the design accounts for the AEC-Q100 automotive qualification if used in vehicle systems. Confirm pin compatibility with existing footprints as the VQFN-32 layout differs from TQFP variants. Check for any recent product change notices regarding assembly sites or materials compliance.

Selection Notes

Select this model when automotive certification is mandatory and LIN bus support is required. The integrated high-accuracy RC48 oscillator simplifies board design by reducing external component count compared to standard variants. Choose this over ATSAMD20 series parts if 5V operation and automotive grade are needed rather than lower voltage industrial use.

Part Context

This component belongs to the Microchip SAMC20 family, designed for cost-sensitive and space-constrained applications. It shares the Cortex-M0+ architecture with the SAMD20 series but adds automotive qualification and specific interface support like LIN. The E17 designation indicates the specific memory configuration and I/O count within the E-series lineup.

Replacement Considerations

ATSAMC20E17A-AUT offers identical electrical specifications but utilizes a TQFP-32 package instead of VQFN-32.
