ATSAMS70N19A-CN

Overview

The ATSAMS70N19A-CN is a 32-bit ARM Cortex-M7 microcontroller from the SAM S70 series, manufactured by Microchip Technology. It features a maximum clock frequency of 300 MHz and includes 512 kB of Flash program memory and 256 kB of SRAM data RAM. The device provides 75 general-purpose I/Os and operates within a supply voltage range of 1.7 V to 3.6 V. It integrates multiple communication interfaces including SPI, UART, USART, and USB. The component supports 12-bit ADC resolution with 10 channels and 12-bit DAC resolution with 2 channels. It is housed in a 100-LFBGA package and functions reliably across an operating temperature range of -40°C to +105°C.

Feature Summary

• High-performance processing capability enabled by the ARM Cortex-M7 core running at up to 300 MHz.
• Integrated analog conversion capabilities featuring 10-channel 12-bit ADC and dual 12-bit DAC for signal processing applications.
• Comprehensive connectivity suite supporting standard serial protocols such as SPI, UART, USART, and USB for peripheral interfacing.

Applications

• Industrial control systems requiring robust real-time processing
• Human-machine interface (HMI) displays utilizing high-speed data transfer
• Automotive infotainment and instrumentation modules

Procurement Notes

Verify the specific suffix CN against official Microchip documentation to confirm regional compliance or material specifications. Ensure the LFBGA-100 package footprint matches the PCB design constraints. Confirm moisture sensitivity level handling requirements during assembly to prevent damage. Cross-reference the exact part number with the latest datasheet revision to validate pinout and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this model when a balance of moderate memory capacity and high processing speed is required. The 512 kB Flash and 256 kB SRAM suit applications that do not demand the larger storage found in higher-end variants like the ATSAMS70N20A-CN. Consider the 100-pin BGA package for space-constrained designs needing extensive I/O without increasing board area significantly compared to QFP options.

Part Context

This component belongs to the SAM S70 family, which targets high-performance embedded applications. It shares architectural similarities with the SAM E70 and SAM V70 series but offers distinct memory configurations and peripheral sets tailored for cost-sensitive yet powerful industrial and consumer electronics. The Cortex-M7 core ensures efficient execution of complex algorithms and DSP tasks.

Replacement Considerations

ATSAMS70N19A-CFN: Offers identical core specifications but utilizes a 100-VFBGA(7x7) package instead of the LFBGA-100. Verify mechanical compatibility if switching packages. ATSAMS70N20A-CN: Provides increased memory (1 MB Flash, 384 kB SRAM) in the same package; suitable if additional storage is needed.
