Overview
The ATSAM4S16CA-CFNR is a 32-bit microcontroller from the Microchip SAM4S series, built on an ARM Cortex-M4 core. It features 1 MB of in-system programmable flash memory and 128 kB of SRAM. The device operates at a maximum clock frequency of 120 MHz and supports a supply voltage range of 1.62 V to 3.6 V. It includes integrated peripherals such as USB, SPI, I2C, UART, and multiple ADCs. The component is housed in a 100-pin VFQFPN package and is rated for industrial operating temperatures ranging from -40°C to +105°C.
Feature Summary
- Integrates an ARM Cortex-M4 processor with single-cycle multiplication and hardware divide capabilities for efficient signal processing.
- Provides extensive connectivity options including USB Full-Speed Device/Host/OTG, multiple serial communication interfaces, and DMA controllers.
- Features robust analog input handling with high-resolution ADCs and comparators suitable for sensor interfacing.
Applications
- Industrial control systems requiring reliable real-time processing
- Smart energy metering applications
- Medical equipment with strict performance requirements
- Consumer appliances with embedded connectivity
Procurement Notes
Verify the suffix CFNR corresponds to the specific tape-and-reel packaging variant distinct from tray packages. Confirm the industrial temperature grade (-40°C to +105°C) matches application thermal constraints. Ensure compatibility with the 1.62V to 3.6V supply domain. Cross-reference the exact part number against the latest Microchip datasheet to confirm pinout and peripheral availability.
Selection Notes
Select this model when 1 MB of flash and 128 kB of RAM are required within a compact 100-pin footprint. The industrial temperature rating makes it suitable for harsh environments compared to commercial grade variants. Consider the VFQFPN package profile for space-constrained PCB designs. Evaluate power consumption profiles against other SAM4S family members if battery life is critical.
Part Context
This component belongs to the SAM4S family, which targets cost-sensitive applications needing Cortex-M4 performance. It shares architectural similarities with the SAM4E and SAM4L series but offers specific memory and peripheral configurations tailored for general-purpose microcontrol. The SAM4S line emphasizes integration of USB and standard serial interfaces for versatile system connectivity.
Replacement Considerations
Consult official substitution guides for equivalent memory and package combinations within the SAM4S family. Verify that alternative parts maintain the same industrial temperature range and package dimensions for direct board compatibility.
