ATSAM4C16CB-AUTR

Overview

The ATSAM4C16CB-AUTR is an ARM Cortex-M4 microcontroller from the SAM4C series, manufactured by Microchip Technology. It features a single-core architecture with 1 MB of Flash memory and 152 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 74 I/O pins, an 8-channel 10-bit ADC, and interfaces such as I2C, SPI, UART, and USART. The component is housed in a TQFP-100 package, rated for industrial temperature ranges (-40°C to +85°C), and utilizes tape-and-reel packaging.

Feature Summary

• Integrates hardware cryptographic accelerators for secure data processing
• Supports Memory Reliability Logic Blocks (MRLB) for enhanced system integrity
• Features dual Cortex-M4 cores for parallel application and security task execution

Applications

• Smart metering systems requiring secure communication
• Industrial control applications demanding high reliability
• Medical devices needing robust data protection

Procurement Notes

Verify the specific suffix 'AUTR' confirms the tape-and-reel packaging format distinct from tray versions. Confirm the 'A' grade indicates industrial temperature range compliance. Ensure the 'U' suffix matches the required RoHS and halogen-free specifications. Cross-reference the full part number against the official Microchip SAM4C datasheet to validate pinout and electrical characteristics before integration.

Selection Notes

Select this variant when a single-core Cortex-M4 solution with integrated security features is required. Compare against dual-core SAM4C models if parallel processing overhead is unnecessary. Verify that the 1 MB Flash capacity meets firmware storage needs. Ensure the TQFP-100 package fits the PCB layout constraints. Check compatibility with existing development tools for the SAM4C family.

Part Context

This component belongs to the SAM4C series, designed for high-performance embedded applications. It builds upon the Cortex-M4 architecture with added security and reliability features. The series targets markets requiring secure boot and protected code execution. It serves as a bridge between standard MCUs and more complex multi-core solutions.

Replacement Considerations

ATSAM4C16CB-AUT: Identical electrical and functional specifications but packaged in trays instead of tape-and-reel. Verify packaging requirements before substitution.
