ATSAMC21G16A-MUT

Overview

The ATSAMC21G16A-MUT is an ARM microcontroller from the Microchip ATSAMC21 series, featuring an ARM Cortex M0+ core. It provides 64 kB of program memory and 8 kB of data RAM within a VQFN-48 package. The device supports a maximum clock frequency of 48 MHz and operates on a 32-bit data bus. It includes two 12-bit ADCs with 14 channels, a 10-bit DAC, and five timers/counters. Electrical specifications include a supply voltage range of 2.7 V to 5.5 V and an operating temperature range of -40°C to +85°C. Interfaces include I2C, LIN, PMBus, Serial, SPI, and USART.

Feature Summary

• Integrates dual 12-bit analog-to-digital converters for precise signal acquisition.
• Supports multiple communication protocols including SPI, I2C, LIN, and USART.
• Features a 10-bit digital-to-analog converter for output generation.
• Includes five timer/counter units for timing and counting applications.

Applications

• Industrial control systems requiring robust communication interfaces
• Automotive electronics compliant with AEC-Q100 standards
• General-purpose embedded applications using ARM Cortex M0+ architecture

Procurement Notes

Verify the specific suffix 'MUT' corresponds to the tape and reel packaging format required for automated assembly processes. Confirm that the 48-pin VQFN footprint matches the target PCB design constraints. Ensure compatibility with the intended operating temperature range of -40°C to +85°C for the final application environment.

Selection Notes

Select this component when 64 kB of flash memory and 8 kB of SRAM are sufficient for the firmware requirements. Choose this model over variants with higher memory sizes if cost or pin count optimization is prioritized. Ensure the design utilizes the available 38 general-purpose I/O pins effectively.

Part Context

This part belongs to the ATSAMC21 family of 32-bit microcontrollers based on the ARM Cortex M0+ processor. It shares architectural similarities with other members like the ATSAMC21G17A but differs in memory capacity. The G-series designation indicates specific pin counts and peripheral configurations distinct from the J-series.

Replacement Considerations

ATSAMC21G17A-MUT offers increased memory capacity while maintaining the same package and core architecture.
