ATSAM4CMP16CC-AUTR

Overview

The ATSAM4CMP16CC-AUTR is a 32-bit microcontroller from the SAM4CM series, featuring dual ARM Cortex-M4 and Cortex-M4F cores operating at a maximum clock frequency of 120 MHz. It integrates 1 MB of Flash program memory and 152 kB of SRAM data RAM within a TQFP-100 package. The device supports a supply voltage range of 1.08 V to 1.32 V and includes six 10-bit ADC channels. It provides 52 general-purpose I/O pins and supports interfaces including SPI, UART, USART, and 2-Wire protocols.

Feature Summary

• Dual-core architecture combining ARM Cortex-M4 and Cortex-M4F processors for integrated application and security processing
• Integrated hardware cryptographic engine supporting secure communication and data protection
• Multi-Rate Linear Clock (MRLC) system for precise timing control in industrial applications

Applications

• Smart metering systems requiring high security and processing performance
• Industrial control units with real-time processing demands
• Secure communication gateways utilizing hardware encryption capabilities

Procurement Notes

Verify the specific suffix 'AUTR' against official Microchip documentation to confirm tape-and-reel packaging and automotive qualification status. Ensure the voltage range specification matches the intended power supply design, as this variant specifies a narrow 1.08 V to 1.32 V range. Cross-reference the datasheet for any recent Product Change Notices affecting pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a dual-core ARM MCU with dedicated hardware crypto acceleration is required for space-constrained designs. The TQFP-100 package offers a balance of I/O count and footprint size. Consider the specific low-voltage operation requirements, as the 1.08 V minimum limit differs from standard 1.8 V variants. Verify that the 152 kB RAM allocation meets the stack and heap requirements for the target firmware complexity.

Part Context

This part belongs to the SAM4CM family, designed for high-performance embedded applications. It extends the single-core SAM4C line by adding a second core specifically for handling security tasks independently. This separation allows the main application core to maintain real-time performance while the secondary core manages cryptographic operations and secure boot processes without interrupting critical system functions.

Replacement Considerations

Consult the Microchip SAM4CM product selector for alternatives with different memory sizes or packages. Verify compatibility with existing board layouts if substituting with other SAM4CM variants, as pin counts and peripheral availability may vary across the family.
