ATSAMG53N19A-AU

Overview

The ATSAMG53N19A-AU is a 32-bit ARM Cortex-M4 microcontroller from the SAM G53 series, operating at up to 48 MHz. It features 512 Kbytes of embedded Flash and 96 Kbytes of SRAM. The device includes an 8-channel 12-bit ADC, two UARTs, one USART, one SPI, three TWI interfaces, and two I2S controllers with PDM support. It operates within a voltage range of 1.62V to 3.6V and supports industrial temperatures from -40°C to +85°C in a 100-pin LQFP package.

Feature Summary

• ARM Cortex-M4 core with DSP instructions and Floating Point Unit (FPU)
• Integrated Event System for peripheral-to-peripheral communication without processor intervention
• Low-power modes including Sleep and Wait with asynchronous partial wake-up capability
• Comprehensive analog and digital peripherals including high-speed I2C and audio interfaces

Applications

• Consumer electronics devices
• Industrial control systems
• PC peripherals
• Audio applications requiring I2S/PDM interfaces

Procurement Notes

Verify the specific ordering code ATSAMG53N19A-AU against official Microchip documentation to confirm package type and temperature range. Ensure compatibility with required voltage levels and interface configurations for the target application design.

Selection Notes

Select this component for applications requiring a balance of processing power and low power consumption. The inclusion of FPU and DSP instructions makes it suitable for signal processing tasks. Verify that the 38 available I/O lines meet system requirements.

Part Context

Part of the Atmel SMART SAM G53 family, designed for cost-sensitive applications needing ARM Cortex-M4 performance. The N variant specifically denotes the 100-pin LQFP package option, distinguishing it from the WLCSP packaged G variant within the same silicon series.

Replacement Considerations

ATSAMG53N19B-AU is a confirmed substitute within the same package and specification profile.
