ATSAMC20J15A-ANT

Overview

The ATSAMC20J15A-ANT is an ARM microcontroller from the SAM C20 series, featuring a Cortex-M0+ core operating at a maximum frequency of 48 MHz. It integrates 32 kB of Flash program memory and 4 kB of SRAM data RAM within a TQFP-64 package. The device supports a supply voltage range of 2.7 V to 5.5 V and includes 52 general-purpose I/O pins. Peripheral interfaces include LIN, I2C, PMBus, SPI, and USART. It offers twelve 12-bit ADC channels and five timer/counters, with an operating temperature range of -40°C to +105°C.

Feature Summary

• Integrated AEC-Q100 automotive qualification for reliability in demanding environments
• Supports multiple communication protocols including LIN, I2C, SPI, and USART
• Features twelve-channel 12-bit analog-to-digital conversion capability
• Includes embedded EEPROM for non-volatile data storage

Applications

• Automotive body electronics and control modules
• Industrial sensor nodes requiring LIN bus connectivity
• Consumer devices needing robust 5V operation
• General-purpose embedded control systems

Procurement Notes

Verify the specific suffix ANT indicates tape and reel packaging when ordering. Confirm the AEC-Q100 qualification status aligns with target automotive or industrial requirements. Ensure the TQFP-64 footprint matches the PCB design constraints. Check for any recent product change notices regarding manufacturing sites or material composition updates.

Selection Notes

Select this component when automotive-grade reliability is required alongside standard 5V logic levels. Compare against the ATSAMD20 series if lower voltage operation is acceptable, as that family lacks the explicit automotive qualification. Consider the ATSAMC21 series if higher memory capacity or additional peripherals are needed while maintaining similar pin counts.

Part Context

This part belongs to the Microchip SAM C20 family, designed for cost-sensitive applications requiring automotive certification. It shares architectural similarities with the SAM D20 but adds specific features like LIN support and extended temperature ranges suitable for under-hood or industrial use cases.

Replacement Considerations

Direct substitutes within the same package and specification include the ATSAMC20J15A-MNT (QFN package) or other SAM C20 variants with matching memory sizes. Verify pin compatibility before swapping packages.
