ATSAM4S16BA-AN

Overview

The ATSAM4S16BA-AN is a 32-bit microcontroller from the Microchip SAM4S series, built on an ARM Cortex-M4 core. It features 1MB of embedded Flash memory and 128KB of SRAM. The device operates at clock speeds up to 120MHz and supports a supply voltage range of 1.62V to 3.6V. It includes various peripherals such as USB, SPI, I2C, and UART interfaces, housed in a surface-mount package suitable for industrial applications.

Feature Summary

• Integrates an ARM Cortex-M4 processor with DSP instruction set support
• Provides extensive connectivity through multiple communication interfaces including USB and Ethernet
• Includes robust power management features with low-power modes and internal regulators

Applications

• Industrial control systems requiring high performance and security
• Smart metering applications utilizing secure boot and data protection
• Consumer electronics needing efficient power management and rich I/O options

Procurement Notes

Verify the specific suffix 'AN' against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints and thermal requirements. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm availability of technical support and datasheets for design-in phase.

Selection Notes

Select this component when a balance of processing power, memory capacity, and peripheral richness is required within the SAM4S family. Consider the 120MHz speed and 1MB Flash for complex firmware execution. Evaluate pin count and package constraints against system layout needs. Compare with other SAM4S variants if different memory sizes or interface sets are preferred.

Part Context

The SAM4S series targets cost-sensitive applications demanding ARM Cortex-M4 performance. It offers pin-to-pin compatibility with previous generations like SAM3S. The series emphasizes security features and low power consumption, making it suitable for a wide range of embedded solutions across industrial and consumer markets.

Replacement Considerations

Check for direct pin-compatible alternatives within the SAM4S family, such as ATSAM4S16CA or ATSAM4S16BA with different suffixes indicating package variations. Verify electrical specifications and memory configurations match before substitution.
