ATSAMD20J17A-ANT

Overview

The ATSAMD20J17A-ANT is a 32-bit ARM Cortex-M0+ microcontroller from the SAM D20J family, manufactured by Microchip Technology. It features 128KB of Flash program memory and 16KB of SRAM data memory. The device operates with a maximum clock frequency of 48 MHz and supports a supply voltage range of 1.62 V to 3.63 V. It includes 52 general-purpose I/O pins, an internal oscillator, and multiple communication interfaces including I2C, SPI, UART, and USART. The component is housed in a 64-pin TQFP package and is rated for industrial operating temperatures between -40°C and +105°C.

Feature Summary

• ARM Cortex-M0+ core architecture providing efficient 32-bit processing capabilities
• Integrated non-volatile Flash memory and static RAM for code and data storage
• Multiple serial communication peripherals supporting standard industrial protocols
• Industrial temperature rating suitable for demanding environmental conditions

Applications

• Industrial control systems requiring robust MCU performance
• Consumer electronics utilizing low-power embedded controllers
• General-purpose embedded applications with serial interface needs

Procurement Notes

Verify the specific suffix 'ANT' corresponds to the 64-TQFP package and industrial temperature grade (-40°C to +105°C) as documented in official Microchip datasheets. Confirm RoHS compliance status through current manufacturer documentation. Ensure compatibility with development tools such as Atmel-ICE or similar debuggers for programming and debugging workflows.

Selection Notes

Select this variant when a 64-pin surface-mount package is required alongside industrial temperature specifications. Compare against other SAM D20J suffixes to ensure the pinout and thermal range match the target PCB design. Verify that the 128KB Flash capacity meets application firmware requirements without necessitating external memory solutions.

Part Context

This component belongs to the SAM D20J series within Microchip's broader SAMD family of 32-bit MCUs. These devices are designed for cost-sensitive and space-constrained applications, offering a balance of performance and power efficiency. The SAM D20J series specifically targets markets requiring reliable embedded control with standard connectivity options.

Replacement Considerations

Cross-reference with other SAM D20J variants such as ATSAMD20J17A-AU or ATSAMD20J17A-CN if package differences (TQFP vs. UFBGA) are acceptable. Ensure functional equivalence regarding memory size and peripheral availability before substituting.
