Overview
The ATSAM4S4CA-CUR is a 32-bit microcontroller from the SAM4S series, featuring an ARM Cortex-M4 core operating at 120MHz. It integrates 256KB of flash memory and 64KB of RAM within a 100-ball BGA package. The device supports a supply voltage range of 1.62V to 3.6V and includes multiple communication interfaces such as USB, SPI, I2C, UART/USART, SSC, IrDA, and EBI/EMI. It also provides analog capabilities with sixteen 12-bit ADC channels and two 12-bit DAC channels.
Feature Summary
- Integrates an ARM Cortex-M4 processor core for high-performance processing
- Includes external bus interface (EBI) and Ethernet MAC interface (EMI) support
- Features comprehensive connectivity options including USB and standard serial protocols
- Provides integrated analog-to-digital and digital-to-analog conversion capabilities
Applications
- Industrial control systems requiring external memory interfacing
- Consumer electronics utilizing USB connectivity
- Medical devices needing precise analog signal acquisition
- Automotive applications supporting robust communication protocols
Procurement Notes
Verify the specific suffix CUR indicates the 100-ball BGA package and industrial temperature rating. Confirm RoHS compliance status through official Microchip documentation. Ensure design-in compatibility with the required pinout and electrical specifications before procurement.
Selection Notes
Select this component when external memory or display interfaces are necessary via the EBI/EMI ports. Compare against other SAM4S variants if lower pin counts or different packaging styles like LQFP are preferred. Consider power consumption requirements relative to the 120MHz operational speed.
Part Context
This part belongs to the SAM4S family of 32-bit microcontrollers based on the ARM Cortex-M4 architecture. The series is designed for applications demanding high performance and rich peripheral sets. The ATSAM4S4CA variant specifically offers 256KB of flash memory.
Replacement Considerations
ATSAM4S4CA-AUR: Same core and memory in 100-LQFP package. ATSAM4S4CA-CU: Same core and memory in 100-TFBGA package.
