Overview
The ATSAM4S8CB-CFN is a 32-bit microcontroller from the Microchip SAM4S series, built on an ARM Cortex-M4 core. It operates at a maximum frequency of 120MHz and features 512KB of in-system programmable flash memory alongside 128KB of SRAM. The device supports a supply voltage range of 1.62V to 3.6V and includes integrated peripherals such as USB, SPI, I2C, and multiple UARTs. It is housed in a 100-pin TFBGA package and is rated for industrial operating temperatures between -40°C and +85°C.
Feature Summary
- Integrates an ARM Cortex-M4 processor with single-cycle multiplication and hardware divide capabilities for efficient digital signal processing.
- Includes a comprehensive set of communication interfaces including USB Full-Speed OTG, Ethernet MAC, and multiple high-speed serial controllers.
- Features advanced analog components with dual 12-bit DACs and multiple 12-bit ADCs for precise signal conditioning.
- Supports low-power operation modes including Sleep, Idle, and Wait, managed by an integrated Power Manager.
Applications
- Industrial automation controllers requiring robust communication protocols
- Medical devices needing precise analog-to-digital conversion
- Consumer electronics utilizing USB connectivity
- Smart metering systems demanding low power consumption
Procurement Notes
Verify the specific suffix 'CFN' corresponds to the TFBGA-100 package and industrial temperature grade (-40°C to +85°C). Confirm that the component meets RoHS compliance requirements for your target market. Ensure design-in compatibility with the SAM4S family development tools and software frameworks provided by Microchip Technology.
Selection Notes
Select this component when a balance of processing power and peripheral richness is required within a compact footprint. The 512KB flash size accommodates complex firmware, while the 120MHz speed ensures responsive real-time control. Consider alternative pinouts or memory sizes within the SAM4S family if interface counts or storage capacity do not align with specific system constraints.
Part Context
This part belongs to the SAM4S series, which targets cost-sensitive applications requiring ARM Cortex-M4 performance. The series offers various memory configurations and packages to suit different form factors. The ATSAM4S8CB variant specifically provides mid-range memory resources suitable for general-purpose embedded control tasks.
Replacement Considerations
Direct replacements within the same package and pinout include other variants in the ATSAM4S8C family with differing memory sizes or temperature grades. Cross-family migration to SAM4E or SAM4N may require schematic and firmware modifications due to architectural differences.
