ATSAMG53G19A-UUT

Overview

The ATSAMG53G19A-UUT is a 32-bit microcontroller based on the ARM Cortex-M4 processor, operating at up to 48 MHz. It features 512 Kbytes of Flash memory and 96 Kbytes of SRAM. The device includes one USART, two UARTs, three TWI interfaces, one SPI, two I2S controllers with PDM support, two 16-bit timers, one RTT, and an 8-channel 12-bit ADC. It operates from 1.62V to 3.6V in a 49-ball WLCSP package.

Feature Summary

• ARM Cortex-M4 core with DSP instructions and Floating Point Unit
• Integrated Event System for peripheral-to-peripheral communication without CPU intervention
• Low-power modes including Sleep and Wait with asynchronous partial wake-up capability
• Comprehensive analog and digital peripherals including high-speed TWI slave

Applications

• Consumer electronics devices
• Industrial control systems
• PC peripheral applications

Procurement Notes

Verify the specific ordering code ATSAMG53G19A-UUT against official Microchip documentation to confirm the WLCSP49 package and industrial temperature range. Ensure compatibility with existing design constraints regarding the 49-ball WLCSP footprint and voltage supply requirements before finalizing procurement.

Selection Notes

Select this component when a compact form factor is required due to the WLCSP package. It is suitable for designs needing moderate processing power with integrated audio interfaces like I2S/PDM. Consider the 48 MHz maximum speed and available GPIO count relative to system interface requirements.

Part Context

This part belongs to the SAM G53 series, which provides a balance of performance and low power consumption. The 'G' suffix indicates the WLCSP package variant, distinguishing it from the LQFP packaged 'N' variants within the same silicon family.

Replacement Considerations

ATSAMG53G19B-UUT is a confirmed substitute within the same package and specification profile.
