ATSAMD20J17A-CNT

Overview

The ATSAMD20J17A-CNT is a 32-bit microcontroller from the Microchip SAM D20J family, featuring an ARM Cortex-M0+ core. It integrates 128KB of Flash memory and 16KB of SRAM. The device operates at a maximum clock frequency of 48MHz and supports a supply voltage range of 2.7V to 5.5V. It includes 20 channels of 12-bit ADC and one 10-bit DAC. The component utilizes a 64-UFBGA package with dimensions of 5x5 mm.

Feature Summary

• Integrates ARM Cortex-M0+ processor for efficient code execution
• Provides extensive analog connectivity via multiple ADC channels and a DAC
• Supports standard communication interfaces including I2C, SPI, and UART/USART

Applications

• Low-power embedded control systems
• Portable battery-operated devices
• Industrial sensor nodes

Procurement Notes

Verify the specific suffix CNT against official Microchip documentation to confirm the 64-UFBGA package type and commercial temperature rating. Ensure compatibility with design tools by checking the latest datasheet revision and errata sheets for silicon-specific limitations before finalizing procurement.

Selection Notes

Select this component when a balance of moderate program memory and high pin count is required in a compact footprint. The 48MHz speed suits applications needing faster processing than baseline Cortex-M0 devices while maintaining low power consumption characteristics typical of the SAM D20 series.

Part Context

This part belongs to the SAM D20J series, designed for cost-sensitive applications requiring more I/O than smaller packages offer. It shares the core architecture with other SAM D20 variants but distinguishes itself through the specific UFBGA packaging and memory configuration optimized for space-constrained designs.

Replacement Considerations

Direct substitutes include ATSAMD20J17A-CN (Tray) and ATSAMD20J17A-MUT (QFN), though package differences require PCB redesign. Cross-family replacements like ATSAMD21 series offer higher performance but may require software adaptation.
