Overview
The ATSAMG53N19B-AU is a 32-bit microcontroller based on the ARM Cortex-M4 processor, operating at a maximum speed of 48 MHz. It features 512 Kbytes of embedded Flash memory and 96 Kbytes of SRAM. The device includes one USART, two UARTs, three I2C interfaces, up to two SPI controllers, two I2S controllers with PDM support, and an 8-channel 12-bit ADC. It operates from 1.62V to 3.6V and is housed in a 100-pin LQFP package.
Feature Summary
- Supports low-power modes including Sleep and Wait, with asynchronous partial wake-up capabilities via SleepWalking technology.
- Integrates an Event System allowing peripherals to react to events without processor intervention.
- Includes DSP instructions and a Floating Point Unit (FPU) for enhanced processing performance.
Applications
- Consumer electronics
- Industrial control systems
- PC peripherals
Procurement Notes
Verify the specific ordering code against official Microchip documentation to ensure correct package type and temperature range. Confirm that the component meets RoHS3 compliance requirements as specified in the datasheet. Ensure compatibility with the intended voltage supply range of 1.62V to 3.6V during system design validation.
Selection Notes
Select this model when a balance of processing power and low power consumption is required. The 100-pin LQFP package provides ample I/O lines for complex peripheral connections. Consider the 48 MHz clock speed and available memory size relative to application software requirements before finalizing the component choice.
Part Context
This part belongs to the SAM G53 series of Flash microcontrollers. It shares core architecture with other variants in the family but differs in package configuration and specific pinout arrangements. The N19 designation indicates the 100-pin LQFP package variant within the series.
Replacement Considerations
Consult official Microchip documentation for verified substitute part numbers. Cross-reference package dimensions and pinouts carefully when considering alternatives to ensure mechanical and electrical compatibility.
