Overview
The ATSAMS70N21A-AN is a 32-bit microcontroller from the Microchip SAM S70 series, featuring an ARM Cortex-M7 core operating at a maximum frequency of 300 MHz. It integrates 2 MB of Flash memory and 384 kB of SRAM within a 100-pin LQFP package. The device supports a supply voltage range of 1.62 V to 3.6 V and includes 75 general-purpose I/Os. Peripheral interfaces include SPI, UART/USART, and USB. It operates within a temperature range of -40°C to +105°C.
Feature Summary
- High-performance processing via ARM Cortex-M7 core with DSP instructions
- Integrated high-density non-volatile memory for complex application storage
- Comprehensive connectivity suite supporting serial and universal bus standards
Applications
- Industrial automation controllers
- Human-machine interface (HMI) displays
- Medical equipment control systems
Procurement Notes
Verify the specific suffix 'AN' corresponds to the 100-LQFP package and commercial temperature grade in official Microchip documentation. Confirm RoHS compliance status through current datasheets. Ensure design compatibility with the specified 1.62V to 3.6V supply voltage range and thermal requirements for the intended operating environment.
Selection Notes
Select this component when a balance of high computational throughput and moderate pin count is required. The 2 MB Flash capacity suits applications needing substantial code storage without external memory. Compare against ATSAMS70N21A-CN if BGA packaging or different thermal characteristics are preferred for the target PCB layout.
Part Context
This part belongs to the SAM S70 family, designed for high-performance embedded applications. It shares architectural similarities with the SAM E70 and SAM V70 series but offers specific memory and peripheral configurations tailored for cost-sensitive yet powerful industrial and consumer electronics solutions requiring robust processing capabilities.
Replacement Considerations
ATSAMS70N21A-CN: Same core and memory, TFBGA package. ATSAME70N21A-AN: Same core and memory, Ethernet support.
