Overview
The ATSAMD51N19A-AU is a 32-bit microcontroller based on the ARM Cortex-M4F core, operating at a maximum frequency of 120 MHz. It features 512 KB of in-system programmable flash memory and 192 KB of SRAM. The device is housed in a 100-TQFP package with 81 I/O lines. It supports a supply voltage range of 1.71 V to 3.63 V and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates an ARM Cortex-M4F processor with hardware floating-point unit for efficient signal processing.
- Includes extensive connectivity options such as USB, SPI, I2C, UART, and CAN interfaces.
- Features multiple high-resolution analog-to-digital converters and digital-to-analog converters.
Applications
- Industrial control systems requiring robust peripheral integration
- Medical devices needing precise analog signal acquisition
- Consumer electronics utilizing USB connectivity
Procurement Notes
Verify the specific suffix 'AU' corresponds to the standard commercial temperature grade and TQFP-100 packaging. Confirm RoHS compliance status through official Microchip documentation prior to procurement. Ensure design compatibility with the 1.71V to 3.63V supply voltage requirements.
Selection Notes
Select this component when a balance of moderate flash capacity and high-speed processing is required. The 100-pin interface provides ample GPIOs for complex peripheral connections. Consider alternative SAM D51 variants if higher memory density or automotive qualification is necessary.
Part Context
This part belongs to the SAM D51 family, designed for applications demanding high performance and low power consumption. It shares architectural similarities with other SAM D51 devices but offers specific memory and pin configurations tailored for general-purpose embedded control tasks.
Replacement Considerations
Check for ATSAMD51N19A-AUT-EFP for tape-and-reel packaging options. Verify ATSAMD51J19A-AU for smaller footprint requirements, noting the reduced pin count and potential I/O limitations compared to the N-series.
