Overview
The ATSAM4E8CB-ANR is a 32-bit ARM Cortex-M4 microcontroller from the Microchip SAM4E series. It integrates 512 kB of Flash memory and 128 kB of SRAM, operating at a maximum clock frequency of 120 MHz. The device features a 16-bit ADC with 8 channels and supports I/O voltages up to 3.3 V. It is housed in an LQFP-100 package and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Integrates high-performance 32-bit ARM Cortex-M4 processor with single-cycle multiplication and hardware division
- Includes advanced analog peripherals such as a 16-bit ADC and multiple comparators for signal processing
- Supports flexible connectivity through integrated USB Device/OTG, CAN, and standard serial interfaces
Applications
- Industrial control systems requiring robust communication protocols
- Medical devices utilizing precise analog-to-digital conversion capabilities
- Consumer electronics featuring USB connectivity and display driving requirements
Procurement Notes
Verify the specific suffix ANR corresponds to the LQFP-100 package and extended temperature range during procurement. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure compatibility with existing design tools and debuggers supporting the SAM4E family architecture.
Selection Notes
Select this component when 512 kB of program storage and 128 kB of data RAM are required for complex firmware applications. Choose the LQFP-100 package if surface-mount space constraints allow for larger footprints compared to BGA options. Consider the 120 MHz performance ceiling against power consumption limits for battery-operated designs.
Part Context
This part belongs to the SAM4E family, designed for applications demanding high performance and rich peripheral sets. It shares architectural similarities with other SAM4E variants but offers specific memory configurations. The family targets industrial and consumer markets needing reliable ARM-based processing solutions.
Replacement Considerations
ATSAM4E8CA-ANR provides identical specifications with potential manufacturing site differences. ATSAM4E8EA-ANR offers the same core but utilizes an LFBGA-144 package instead of LQFP-100.
