ATSAMD20J14B-MUT

Overview

The ATSAMD20J14B-MUT is a Microchip Technology ARM microcontroller based on the Cortex-M0+ core, operating at a maximum frequency of 48 MHz. It features 16 kB of Flash program memory and 2 kB of SRAM data RAM within a 64-pin VQFN package. The device supports a supply voltage range of 1.62 V to 3.63 V and includes 52 general-purpose I/O pins. Integrated peripherals include a 12-bit ADC with 20 channels, a 10-bit DAC, eight timers/counters, and communication interfaces such as I2C, SPI, and USART.

Feature Summary

• Integrates an ARM Cortex-M0+ processor core for efficient code execution in low-power applications.
• Provides flexible connectivity through multiple serial communication interfaces including I2C, SPI, and USART.
• Includes high-resolution analog-to-digital conversion capabilities with up to 20 input channels.

Applications

• Low-power industrial control systems
• Battery-operated consumer electronics
• Simple sensor interface nodes

Procurement Notes

Verify the suffix 'MUT' indicates tape and reel packaging rather than tray. Confirm the specific temperature grade and RoHS compliance status directly with the manufacturer or authorized distributor documentation prior to ordering. Ensure the component matches the required pinout and electrical specifications for the target design.

Selection Notes

Select this model when a balance of moderate memory capacity and extensive I/O count is required in a compact footprint. Compare against the ATSAMD20J14B-MU if tray packaging is preferred. Consider higher memory variants like the ATSAMD20J18 series if larger code storage is needed.

Part Context

This component belongs to the SAM D20 family of 32-bit ARM Cortex-M0+ microcontrollers. It is designed for applications requiring low power consumption and cost-effective performance. The J14 variant specifically denotes the 16 kB Flash and 2 kB SRAM configuration within the J-series pinout.

FAQ

What is the difference between the ATSAMD20J14B-MU and ATSAMD20J14B-MUT?

The primary difference is the packaging format. The -MU suffix indicates Tray packaging, while the -MUT suffix indicates Tape and Reel packaging for automated assembly.

Does the ATSAMD20J14B-MUT support USB connectivity?

No, the ATSAMD20J14B-MUT does not include a built-in USB controller. It relies on standard serial interfaces like USART, SPI, and I2C for communication.
