ATSAMC21G15A-MNT

Overview

The ATSAMC21G15A-MNT is an ARM Cortex-M0+ microcontroller from the SAM C21 series, designed for functional safety applications. It features a 48 MHz maximum clock frequency and integrates 32 kB of Flash program memory with 4 kB of SRAM data RAM. The device operates within a voltage range of 2.7 V to 5.5 V and supports an extended industrial temperature range from -40°C to +105°C. It includes a 12-bit ADC with 14 channels, a 10-bit DAC, and five timer/counters. Connectivity options include I2C, SPI, USART, LIN, and PMBus interfaces. The component is housed in a 48-pin VQFN package and holds AEC-Q100 qualification.

Feature Summary

• Functional Safety (FuSa) compliant design architecture
• Integrated advanced analog peripherals including high-resolution ADCs and DACs
• Support for automotive-grade reliability standards
• Flexible communication interface suite for system integration

Applications

• Automotive body electronics systems
• Industrial control units requiring functional safety certification
• Consumer appliances with extended temperature operation needs
• General-purpose embedded controllers in harsh environments

Procurement Notes

Verify the specific suffix 'MNT' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the AEC-Q100 qualification status meets the specific automotive grade requirements of your target application. Ensure compatibility with the 48-VQFN footprint during PCB layout finalization. Cross-reference the latest datasheet revision to confirm any errata or silicon updates relevant to the production batch.

Selection Notes

Select this component when a Cortex-M0+ core with functional safety capabilities is required alongside moderate memory resources. It is suitable for designs needing 5V tolerance on I/O pins while operating at lower supply voltages. Consider this part over non-FuSa variants if automotive or high-reliability industrial certifications are mandatory. Evaluate the 38 available I/O lines against pin count requirements before choosing larger packages in the same family.

Part Context

This microcontroller belongs to the Microchip SAM C21 family, which targets functional safety applications using the ARM Cortex-M0+ processor.
