ATSAM4E16CB-ANR

Overview

The ATSAM4E16CB-ANR is a 32-bit ARM Cortex-M4 microcontroller from the Microchip SAM4E series, housed in a 100-pin LQFP package. It features a maximum clock frequency of 120 MHz and integrates 1 MB of Flash program memory with 128 kB of SRAM data memory. The device includes a 16-bit ADC with 12 channels and supports multiple communication interfaces including I2C, SPI, and USART. Operating within a voltage range of 1.08 V to 1.32 V for the core and 3.3 V for I/O, it functions reliably between -40°C and +105°C.

Feature Summary

• Integrates an ARM Cortex-M4 processor core optimized for digital signal processing tasks.

Applications

• Industrial automation systems
• Process control applications
• Communication and networking devices

Procurement Notes

Verify the specific suffix ANR against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing board layouts for the LQFP-100 footprint. Confirm that the 1.08 V to 1.32 V core voltage requirements align with the system power design. Check for moisture sensitivity levels and reflow soldering profile constraints during assembly.

Selection Notes

Select this component when a balance of high-performance processing and moderate memory capacity is required. The 120 MHz speed and 1 MB Flash suit complex firmware implementations. Consider the LQFP-100 package for ease of prototyping compared to BGA options. Verify peripheral availability matches interface needs, such as the specific count of timers and ADC channels.

Part Context

This part belongs to the SAM4E family, designed for cost-sensitive applications requiring robust performance. It shares architectural similarities with other SAM4E variants but differs in memory size and pin count. The series targets embedded control tasks where efficient code execution and low power consumption are critical.

Replacement Considerations

Consult official cross-reference guides for compatible parts. Substitutes must match the ARM Cortex-M4 architecture and similar memory configurations. Verify pinout compatibility if replacing directly on a PCB. Ensure thermal and electrical specifications meet or exceed original requirements.
