ATSAM4C32EA-AU - Dual-Core 120MHz MCU | Microchip
Артикул: ATSAM4C32EA-AU ✗ Снят с производстваATSAM4C32EA-AU Обзор
A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripheral interfaces, and control logic on one device. The ATSAM4C32 belongs to the SAM4C family of system-on-chip devices, placing it within the hierarchy of embedded MCU, processor, semiconductor, and industrial-control electronics. Its dual architecture allows one core to execute control tasks while the other handles communication, data processing, or time-sensitive operations.
Key device characteristics include a maximum operating frequency of 120 MHz, 2 MB of embedded Flash, and as much as 304 KB of SRAM. Each processor includes an on-chip cache according to the manufacturer datasheet. The ATSAM4C32EA-AU also includes cryptographic functionality and is identified as a green, industrial-temperature device in the product listing. Its 144-LQFP package provides a high pin count for external peripheral connectivity.
The dual Cortex-M4 architecture supports parallel software tasking without requiring a separate microcontroller. This can improve responsiveness in energy-management systems that must coordinate sensing, communications, control loops, and safety-related monitoring. The shared system-on-chip integration also reduces the need for discrete processing components while preserving dedicated real-time execution capability.
Typical applications include smart energy meters, industrial automation controllers, connected sensing equipment, building-control systems, communications equipment, and embedded gateways. The 120 MHz processing capacity is suitable for protocol handling and supervisory control, while the two cores can separate background processing from time-sensitive control tasks.
Designers should confirm pin assignments, peripheral multiplexing, power requirements, clock configuration, and memory constraints against the manufacturer datasheet before layout release. Because this is a 144-pin LQFP device, careful escape routing and thermal assessment are important. Microchip states that the ATSAM4C32 family is not recommended for new designs and recommends the PIC32CXMTC/MTG device family or its associated evaluation kits as an alternative direction.
This page consolidates the exact orderable-part information, verified technical characteristics, lifecycle guidance, application context, and design considerations needed to assess the ATSAM4C32EA-AU against a new embedded-control project.

Типичное применение
ATSAM4C32EA-AU подходит для 6 применениеs: Smart Energy Metering, Industrial Automation Controller, Connected Sensor and Condition Monitoring, Building Automation and HVAC Control, Communications Gateway and Protocol Converter, Embedded Control and Real-Time Processing.
Smart Energy Metering
The ATSAM4C32EA-AU fits smart energy meters that must combine measurement processing, data handling, communications, and configuration logic. Its two 120 MHz ARM Cortex-M4 cores allow a real-time acquisition and control workload to run separately from protocol or background-processing tasks. The 2 MB embedded Flash accommodates metering logic, communications stacks, and update routines, while as much as 304 KB of SRAM supports working data. The 144-LQFP package provides extensive connections for sensors, display interfaces, communications, and secure metering functions. The manufacturer positions the ATSAM4C32 family specifically for smart-energy system-on-chip designs.
Industrial Automation Controller
The ATSAM4C32EA-AU is appropriate for industrial automation equipment requiring real-time control alongside supervisory logic. One Cortex-M4 core can execute timing-critical acquisition or actuator control, while the second handles state management, diagnostics, communications, and data logging. Both cores operate at up to 120 MHz, providing useful throughput for multi-loop controllers and gateway-class equipment. Its 144-LQFP package exposes a large number of external signals for sensors, isolated interfaces, status indicators, and field-bus connectivity. The 1.2 V to 3.3 V operating range supports integration into modern embedded industrial control systems.
Connected Sensor and Condition Monitoring
The ATSAM4C32EA-AU can support connected sensing systems that combine local signal processing with network communication and long-running control functions. Two Cortex-M4 cores allow sensor filtering or condition-monitoring algorithms to execute independently from communications and system-management tasks. The 2 MB embedded Flash provides room for protocol stacks and application firmware, while up to 304 KB of SRAM accommodates buffers and working state. Its high-pin-count 144-LQFP package is useful when a design requires numerous digital I/O, analog-adjacent control signals, communication interfaces, and debug connections on a single microcontroller.
Building Automation and HVAC Control
The ATSAM4C32EA-AU suits building controllers and HVAC supervisory systems that must coordinate many inputs, outputs, and communication tasks. The dual 120 MHz Cortex-M4 architecture can divide deterministic control functions from configuration, logging, and network communication. Its embedded 2 MB Flash supports application code and protocol storage, and the available SRAM supports concurrent task state. The 144-LQFP package offers enough pin count for sensors, actuators, communications, and status interfaces without relying on multiple low-pin-count microcontrollers. These characteristics support compact embedded controllers for environmental monitoring and building equipment.
Communications Gateway and Protocol Converter
The ATSAM4C32EA-AU is well matched to communications equipment that translates between multiple field protocols or maintains separate real-time and network-processing tasks. Each Cortex-M4 core can operate at up to 120 MHz, enabling one side of the device to service a deterministic interface while the other manages framing, routing, diagnostics, or host communication. With 2 MB of embedded Flash and up to 304 KB of SRAM, the device can host several firmware modules without an external memory bus. The 144-LQFP package supports multiple serial, network, status, and configuration interfaces for a multi-protocol gateway design.
Embedded Control and Real-Time Processing
The ATSAM4C32EA-AU can divide real-time control from supervisory processing in embedded systems where deterministic response matters. One 120 MHz Cortex-M4 core can service periodic sampling or actuator tasks, while the other handles higher-level logic, diagnostics, communications, or firmware coordination. The 2 MB embedded Flash and up to 304 KB of SRAM provide substantial integrated memory for a compact control platform. Its 144-LQFP package provides extensive peripheral connectivity for mixed signal conditioning and external interfaces. The architecture is particularly relevant to energy, industrial, and communications products that benefit from parallel execution without introducing a second processor package.

Заметки по проектированию
Reserve space for the complete 144-LQFP footprint and route high-speed communication and debug interfaces according to the manufacturer pin-description table. The 20 x 20 mm package has fine-pitch leads on all four sides, making escape routing and via placement the primary layout challenges. Confirm exposed-pad, power, ground, and decoupling requirements for the exact ordering code before releasing artwork, and use the manufacturer package drawing rather than estimating pad geometry.
Partition the 1.2 V to 3.3 V supply requirements according to the manufacturer power-supply recommendations. Place the required input, output, and bypass capacitors close to their designated pins, observe permitted capacitor characteristics, and provide low-impedance paths for each supply domain. The processor and memory domains can be sensitive to supply disturbance, so validate startup sequencing, voltage ramps, and load-transient performance across the intended operating range.
Assess junction temperature using the final PCB copper area, enclosure, ambient temperature, and the processor's actual activity profile. A 144-LQFP package can provide substantial exposed copper access, but thermal performance depends on layer count, via placement, and heat spreading into the board rather than package size alone. Verify the maximum operating temperature and power dissipation limits in the manufacturer datasheet, and run thermal testing at maximum clock activity rather than relying on idle-condition temperature rise.
Do not treat a similarly named ATSAM4C32 orderable code as an unconditional substitute. Confirm the exact suffix, package, temperature classification, pin assignment, and intended new-design status. Microchip Technology states that ATSAM4C32 is not recommended for new designs and points to the PIC32CXMTC/MTG family as an alternative direction, so a replacement program should include peripheral mapping, firmware, boot, and PCB review rather than a simple bill-of-material substitution.
Информация о соответствии
The product listing identifies the device as green and intended for industrial-temperature operation, but it does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because this is an industrial-temperature microcontroller rather than an automotive-qualified ordering code.
