ATSAM4CMP16CA-AUR

Overview

The ATSAM4CMP16CA-AUR is a 32-bit microcontroller from the Microchip SAM4CMP series, featuring an ARM Cortex-M4 core with integrated cryptographic acceleration. It operates at a maximum frequency of 120 MHz and includes 1 MB of embedded Flash memory and 152 KB of SRAM. The device supports a supply voltage range of 1.08 V to 1.32 V and utilizes a 100-pin LQFP package. Key peripherals include a 10-bit ADC, USB interface, I2C, SPI, and UART/USART controllers.

Feature Summary

• Integrated hardware cryptographic engine for secure data processing
• ARM Cortex-M4 core with DSP instruction set support
• Low-voltage operation capability down to 1.08 V
• On-chip USB 2.0 device controller with transceiver

Applications

• Secure IoT sensor nodes requiring local encryption
• Industrial control systems with low-power constraints
• Consumer electronics with USB connectivity needs
• Smart metering applications demanding data security

Procurement Notes

Verify the specific suffix 'AUR' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure the 1.08V–1.32V supply voltage requirement aligns with your system design, as it differs from standard 3.3V logic families. Cross-reference the 100-LQFP package dimensions with your PCB footprint library before finalizing procurement.

Selection Notes

Select this component when both high-performance cryptographic operations and ultra-low voltage operation are required. It serves as a suitable alternative to standard SAM4C devices if power efficiency below 1.2V is critical. Consider the 1 MB Flash capacity for complex firmware requirements and verify that the 152 KB RAM suffices for real-time data handling in your specific application context.

Part Context

This part belongs to the SAM4CMP family, which extends the standard SAM4C architecture with dedicated hardware crypto modules. It targets applications where security and power efficiency are paramount. The device maintains pin compatibility within its series while offering enhanced protection features compared to non-crypto variants.

Replacement Considerations

Consult the official SAM4CMP datasheet for direct pin-to-pin substitutes within the same series. Verify that any replacement maintains the 1.08V–1.32V operating voltage range and identical 100-LQFP package specifications.
