ATSAM4CMP32CB-AUR - Dual-Core 120MHz 2MB Flash MCU | Microchip
MPN: ATSAM4CMP32CB-AUR ✓ فعالATSAM4CMP32CB-AUR جائزہ
A microcontroller (MCU) is a single-chip embedded computer integrating a processor core, memory, and peripherals on one die. Within the power management hierarchy, the SAM4CM family sits at the system-on-chip (SoC) level: it combines general-purpose MCU functionality (Cortex-M4 with FPU) with a dedicated second core and metrology-class analog peripherals purpose-built for energy measurement, extending Atmel's well-established SAM4 architecture.
Key features include a dual-core 120 MHz Cortex-M4/M4F subsystem, 2MB embedded Flash, integrated hardware crypto acceleration, and metrology capability achieving up to class 0.2 accuracy over a dynamic range of 3000:1, per the manufacturer product page. The 7-channel poly-phase front end eliminates discrete metering AFEs, reducing BOM cost and board area.
Architecturally, the SAM4CMP32 partitions resources between the two cores, letting one core run metering DSP algorithms while the other handles communication (UART, SPI, I2C), protocol stacks, and UI. Power supplies span 1.2V/1.8V/2.5V/3.3V domains per distributor listings.
Typical applications include residential electricity meters, poly-phase industrial energy meters, and industrial power monitoring systems operating across the industrial temperature range.
Design consideration: as a factory-programmable metering SoC, confirm the metrology firmware provision and power-domain sequencing early in the design.
This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not consolidated in the manufacturer datasheet.

عام استعمالات
ATSAM4CMP32CB-AUR کے لیے موزوں ہے 6 ایپلیکیشنs: Poly-Phase Industrial Electricity Meters, Residential Smart Meters, Industrial Power Monitoring and Submetering, Solar Inverter and Energy Harvesting Systems, Smart Grid Communication Gateways, Building Energy Management and Load Control.
Poly-Phase Industrial Electricity Meters
The ATSAM4CMP32CB-AUR is purpose-built for poly-phase metering: its 7-channel front end samples three-phase voltages and currents simultaneously while the dedicated Cortex-M4F core executes metrology DSP achieving class 0.2 accuracy over a 3000:1 dynamic range. The second 120 MHz core independently runs communication stacks (DLMS/COSEM over PLC, RF, or UART), so heavy protocol traffic does not disturb metrology sampling. Placing metering and application workloads on separate cores also shortens certification cycles because calibration firmware is isolated from application changes. Industrial temperature range qualification suits outdoor cabinet-mounted meters.

Residential Smart Meters
For residential smart energy meters, the ATSAM4CMP32CB-AUR integrates the metrology front end, application MCU, and hardware crypto in one SoC, cutting bill of materials versus discrete MCU-plus-AFE designs. Class 0.2 accuracy with 3000:1 dynamic range covers household load profiles from standby draws to peak appliance currents. The crypto engine secures firmware updates and prepayment credentials, while the 2MB Flash hosts full DLMS/COSEM stacks plus headroom for future utility feature upgrades via OTA. Factory-programmable provisioning from MicrochipDirect allows per-meter key injection at manufacture.

Industrial Power Monitoring and Submetering
In industrial power quality monitors and submeters, the dual-core 120 MHz Cortex-M4F provides the arithmetic throughput for continuous RMS, harmonic, and power-factor calculations while the second core manages Modbus, Ethernet gateway bridges, or local logging. The 7-channel poly-phase front end handles three-phase four-wire and three-phase three-wire topologies, and the 3000:1 dynamic range captures both lightly loaded branches and main feeds. Hardware crypto protects billing-grade data. The 100-LQFP 14x14 mm footprint fits compact DIN-rail submeter form factors.

Solar Inverter and Energy Harvesting Systems
Grid-tied solar inverters and energy storage systems require revenue-grade generation metering: the ATSAM4CMP32CB-AUR measures bidirectional energy flow with class 0.2 accuracy across a 3000:1 dynamic range, covering both export and import conditions. One 120 MHz core runs inverter control support and metrology sampling while the other executes grid-protocol communication (such as utility telemetry links), keeping timing-sensitive measurement isolated from network traffic. The 1.2V/1.8V/2.5V/3.3V supply domains integrate cleanly with typical inverter auxiliary rails. Hardware crypto supports utility authentication requirements.

Smart Grid Communication Gateways
Data-concentrator and metering gateway nodes benefit from the ATSAM4CMP32CB-AUR's dual-core split: one core handles time-critical field-bus polling of downstream meters (RF, PLC, or RS-485) while the other runs upstream backhaul stacks. The 2MB Flash stores protocol conversion tables, security certificates, and buffering for thousands of meter reads. The crypto engine enforces mutual authentication with head-end systems, and the industrial temperature range suits pole-top and cabinet installations. Pin-compatibility with other SAM4CM parts enables a single gateway PCB across Flash-density and core-count SKUs.

Building Energy Management and Load Control
Commercial building energy management systems use the ATSAM4CMP32CB-AUR as a metering and control node: the poly-phase front end meters distribution panels at class 0.2 accuracy while the second 120 MHz Cortex-M4 core runs BACnet/Modbus interfaces and load-shedding logic. The 3000:1 dynamic range is essential because panel loads swing between night-time idle and daytime peak. Flash-based field updates allow tariff and control logic revisions on site, and the crypto engine protects demand-response commands. Its 100-LQFP package suits panel-mounted control boards.

ڈیزائن نوٹس
The ATSAM4CMP32CB-AUR uses four supply domains (1.2V core, 1.8V, 2.5V, 3.3V). Provide independent LDO or DC-DC regulation per domain with clean sequencing per the SAM4CM datasheet power-up requirements. The metrology analog front end is accuracy-critical: isolate its 2.5V/3.3V analog supply from switching-regulator ripple with an LC filter or dedicated low-noise LDO, since supply noise directly degrades the class 0.2 / 3000:1 dynamic range measurement floor.
On the 100-LQFP 14x14 mm footprint, route the 7 metrology analog input channels as short, symmetric differential pairs with kelvin connections to shunt resistors, and keep them away from the crystal and any switched-mode power section. Place a solid ground plane under the analog region and split digital/analog returns at a single point. Decouple every supply pin with 100 nF ceramics placed within 2 mm of the pin, plus bulk 10 uF per domain.
Do not assume the single-core CMS variant is a firmware-compatible substitute: the dual-core CMP device requires core-partitioned firmware and its metrology libraries target the second core. Also confirm metrology firmware provisioning (factory-programmable via MicrochipDirect) at order time - the 'CB' Flash density must match your final firmware plus DLMS/COSEM stack footprint, so re-verify Flash utilization before switching to the 1MB CA/CMP16 alternatives.
