ATSAMG54G19B-UUT

Overview

The ATSAMG54G19B-UUT is a 32-bit ARM Cortex-M4 microcontroller operating at up to 96 MHz. It features 512 Kbytes of Flash and 96 Kbytes of SRAM. The device includes an 8-channel 12-bit ADC, two I2S controllers with PDM support, three TWI interfaces, one USART, two UARTs, and one SPI. It operates from 1.62V to 3.45V in a 49-ball WLCSP package.

Feature Summary

• Supports SleepWalking asynchronous partial wake-up on UART and TWI
• Includes Event System for peripheral-to-peripheral communication without processor intervention
• Features DSP instructions and Floating Point Unit (FPU)
• Provides high-precision internal RC oscillator with in-application trimming

Applications

• Consumer electronics
• Industrial control systems
• PC peripherals

Procurement Notes

Verify the ordering code matches ATSAMG54G19B-UUT to confirm the WLCSP49 package and tape-and-reel carrier type. Ensure the industrial temperature range (-40°C to +85°C) aligns with system requirements. Confirm voltage supply specifications match the 1.62V to 3.45V operational limits.

Selection Notes

Select this component when a compact 49-ball WLCSP footprint is required instead of the LQFP100 variant. It offers identical core performance and memory to the N-series but differs only in physical packaging. Consider the specific pinout mapping differences between G and N series variants during PCB layout.

Part Context

This part belongs to the SAM G54 series of Atmel | SMART ARM-based Flash MCUs. It shares the same core architecture and peripheral set as the ATSAMG54N19B-AU, differing primarily in the package style. The series targets applications requiring a balance of processing power and low power consumption.

Replacement Considerations

ATSAMG54N19B-AU serves as a functional equivalent with identical electrical characteristics, utilizing a 100-pin LQFP package instead of WLCSP.
