Overview
The ATSAM4S16CA-AU is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at a maximum frequency of 120 MHz. It features 1 MB of in-system programmable flash memory and 128 KB of SRAM. The device includes sixteen 12-bit ADC channels and two 12-bit DAC outputs. Connectivity options encompass EBI/EMI, I2C, IrDA, SD/MMC card interface, SPI, SSC, UART/USART, and USB 2.0 OTG. It operates within a supply voltage range of 1.62 V to 3.6 V and supports an industrial temperature range of -40°C to +85°C.
Feature Summary
- Integrates an ARM Cortex-M4 processor with hardware floating-point unit for high-performance signal processing.
- Provides extensive peripheral connectivity including USB 2.0 OTG, Ethernet MAC, and multiple serial interfaces.
- Features robust analog capabilities with high-resolution ADCs and DACs for sensor interfacing.
Applications
- Industrial control systems requiring real-time processing
- Medical devices needing precise analog signal acquisition
- Consumer electronics utilizing USB connectivity
Procurement Notes
Verify the specific suffix 'AU' confirms the 100-LQFP package and industrial temperature grade. Confirm RoHS compliance status through official Microchip documentation prior to integration. Ensure design-in compatibility with existing power supply rails matching the specified voltage range.
Selection Notes
Select this component when 1 MB of program storage and 128 KB of RAM are required alongside USB and Ethernet capabilities. Compare against SAM4N series if lower pin counts or reduced peripheral sets suffice. Evaluate SAM4L series for ultra-low-power applications where performance requirements are less demanding.
Part Context
This part belongs to the SAM4S family, designed for applications demanding high performance and rich connectivity. It serves as a successor to the SAM7S series, offering enhanced processing power and integrated peripherals suitable for complex embedded tasks in industrial and consumer markets.
Replacement Considerations
ATSAM4S16BA-AU offers identical specifications in a 64-pin LQFP package. ATSAM4SA16CA-CFU provides the same functional core in a 100-VFBGA package for space-constrained designs.
