ATSAM4C16CB-AUT

Overview

The ATSAM4C16CB-AUT is an ARM microcontroller from the SAM4C series, manufactured by Microchip Technology. It features a dual-core ARM Cortex-M4/M4F architecture operating at a maximum clock frequency of 120 MHz. The device integrates 1 MB of embedded Flash memory and 128 kB of SRAM within a 100-pin LQFP package. It supports a supply voltage range of 1.62 V to 3.6 V and operates within an industrial temperature range of -40°C to +85°C. Key peripherals include eight 10-bit ADC channels, multiple communication interfaces such as I2C, SPI, and UART/USART, and various timers.

Feature Summary

• Dual-core ARM Cortex-M4/M4F architecture for integrated application and security processing
• Embedded cryptographic engine supporting secure data handling
• Multiple high-speed communication interfaces including SPI, I2C, and USART
• Industrial temperature rating suitable for demanding environments

Applications

• Smart metering systems requiring secure data transmission
• Industrial control applications with strict environmental tolerances
• Secure access control devices utilizing built-in cryptography
• Automotive infotainment subsystems needing robust processing

Procurement Notes

Verify the specific suffix 'AUT' corresponds to the required industrial temperature grade (-40°C to +85°C) and lead-free packaging status. Confirm that the 100-LQFP package dimensions match the target PCB footprint. Ensure compatibility with existing firmware libraries for the SAM4C series before procurement.

Selection Notes

Select this component when a dual-core solution is necessary to separate real-time tasks from security functions. Compare against single-core variants if memory requirements are lower. Consider the 120 MHz performance ceiling relative to power consumption constraints in battery-operated designs.

Part Context

This part belongs to the SAM4C family, designed for high-performance applications. It shares pin compatibility with other SAM4C variants but differs in memory capacity. The 'A' indicates automotive or extended industrial qualification, while 'T' denotes tape and reel packaging.

Replacement Considerations

ATSAM4C16CA-AU offers similar specifications in a different package variant. ATSAM4C8CB-AUT provides reduced memory capacity for cost-sensitive applications. Cross-referencing with ATSAM4S series may be possible for single-core needs.
