ATSAM4CMP16CC-AU - Dual-Core Cortex-M4 120MHz 1MB MCU | Microchip
MPN: ATSAM4CMP16CC-AU ✓ Hoạt độngATSAM4CMP16CC-AU Tóm tắt
A metering MCU is a class of microcontroller that integrates the compute cores, crypto acceleration, and analog/peripheral resources needed to measure electrical energy with utility-grade accuracy. The ATSAM4CMP16 belongs to the ARM Cortex-M4 microcontroller hierarchy (MCU -> embedded processor -> semiconductor), positioned by Microchip as a seamless extension of the SAM4 family and the SAM4C family, targeting smart energy infrastructure.
Key features include the dual-core Cortex-M4/M4F architecture (one core dedicated to metrology computation, the other to communication and application logic), hardware cryptographic acceleration, and 1 MB of on-chip Flash for program storage. The dual-core split allows the metrology core to sustain class 0.2 energy accuracy without being disturbed by communication stacks.
According to Microchip product data, the SAM4CMP16 achieves class 0.2 metrology accuracy over a dynamic range of 3000:1 across the industrial temperature range. The device operates from multiple supply domains (1.2 V, 1.8 V, 2.5 V, and 3.3 V as listed by distributors), and the -AU suffix denotes the green, industrial-temperature 100-pin LQFP (14x14) package in tray packaging.
Typical applications include residential smart energy meters, poly-phase industrial metering, energy monitoring gateways, and sub-metering systems where secure, accurate energy measurement and robust communication interfaces must coexist on a single chip.
Designers should budget dual-core flash and SRAM partitioning early, since the two Cortex-M4 cores share on-chip memories, and should plan power supply sequencing across the device multiple voltage domains.

Ứng dụng tiêu biểu
ATSAM4CMP16CC-AU phù hợp cho 6 Áp dụngs: Residential Smart Energy Meters, Poly-Phase Industrial Metering, Sub-Metering and Tenant Billing Systems, Energy Monitoring Gateways, Solar Inverter Energy Measurement, Secure Industrial Data Loggers.
Residential Smart Energy Meters
The ATSAM4CMP16CC-AU is purpose-built for residential smart metering: Microchip specifies class 0.2 metrology accuracy over a 3000:1 dynamic range, sufficient for utility billing in single-phase residential installations. One Cortex-M4F core runs the metrology computation continuously while the second core handles PLC, RF, or UART-based communication to data concentrators, preventing communication stack jitter from disturbing energy calculations. The on-chip hardware crypto acceleration supports secure meter-key storage and authenticated firmware required by utility deployments, and the 1 MB Flash accommodates metrology firmware plus full protocol stacks in the compact industrial-temperature 100-LQFP (14x14 mm) package.

Poly-Phase Industrial Metering
For three-phase poly-phase industrial meters, the SAM4CMP16 SoC processes multiple voltage and current channels while maintaining class 0.2 billing accuracy across the 3000:1 dynamic range specified by Microchip. The dual-core architecture lets one core execute per-phase metrology algorithms while the second core manages Modbus/DLMS communication, event logging, and tariff logic. Industrial temperature rating and the green 100-pin LQFP package suit panel-mounted meter hardware, and hardware cryptographic acceleration protects against tampering. Designers should allocate Flash carefully, as poly-phase firmware plus DLMS/COSEM stacks can approach the 1 MB limit; the ATSAM4C32C-AU offers 2 MB in the same footprint if more code space is needed.

Sub-Metering and Tenant Billing Systems
Sub-metering installations in commercial buildings and multi-tenant facilities demand billing-grade accuracy at low per-unit cost. The ATSAM4CMP16CC-AU delivers the required class 0.2 accuracy (per Microchip data) while integrating crypto acceleration for data integrity toward billing backends, eliminating a separate security IC in cost-sensitive designs. The dual-core split isolates measurement firmware from building-automation communication such as RS-485 or wireless modules, and the 1 MB Flash retains multiple meter profiles and load-profile logs. Its industrial temperature range and LQFP solderability support DIN-rail meter housings with conformal coating, and the same-footprint SAM4CM family enables a scalable product line from 512 KB to 2 MB.

Energy Monitoring Gateways
Energy monitoring gateways aggregate data from multiple meters and forward it over Ethernet, cellular, or LoRa links. The ATSAM4CMP16CC-AU fits as the local measurement and preprocessing node: its 120 MHz dual-core Cortex-M4/M4F can run one core on real-time waveform sampling and feature extraction (RMS, power factor, harmonics) while the second core formats and queues payloads for the uplink radio. The 1 MB Flash stores both the metrology engine and lightweight network protocol firmware, and hardware crypto accelerates TLS-style session establishment where supported by the stack. Designers must budget the multiple supply rails (1.2 V, 1.8 V, 2.5 V, 3.3 V) of the device in gateway power-supply design.

Solar Inverter Energy Measurement
Grid-tied solar inverters require revenue-accurate measurement of generation and export. The ATSAM4CMP16CC-AU provides the class 0.2 metrology core (per Microchip specification over a 3000:1 dynamic range) needed for feed-in tariff billing, with the second Cortex-M4 core available for inverter control-adjacent tasks such as communication, logging, and anti-islanding reporting. Its hardware crypto acceleration supports utility interconnection security requirements, and the industrial-temperature 100-LQFP (14x14 mm) package withstands inverter enclosure temperatures. Because inverter environments are electrically noisy, designers should pair the SoC with proper isolation and filtering on current-transformer inputs to preserve the specified accuracy in the presence of switching ripple.

Secure Industrial Data Loggers
Beyond metering, the SAM4CMP16 dual-core SoC serves secure industrial data loggers that record analog process or energy data over long periods. The 120 MHz Cortex-M4F core with FPU handles DSP-style signal conditioning (filtering, RMS, FFT) of sampled channels, while the second core manages file systems on external memory, real-time clocks, and communication. Hardware cryptographic acceleration authenticates logged records for regulatory audit trails, and 1 MB Flash plus external memory interfaces retain firmware, calibration tables, and configuration. The industrial temperature rating and RoHS-green LQFP package suit permanently installed plant equipment, and the same-footprint family (512 KB to 2 MB) lets logger variants be scaled without PCB respins.

Ghi chú thiết kế
Distributor data lists the ATSAM4CMP16CC-AU as operating across 1.2 V, 1.8 V, 2.5 V, and 3.3 V supply domains, implying multiple internal/external rails. Design a clean, sequenced power tree with dedicated LDOs or a PMIC for the core and I/O domains, and add 100 nF ceramic decoupling at every supply pin pair of the 100-LQFP plus bulk 10 uF capacitance per rail. Metering accuracy is directly sensitive to supply ripple on analog supply pins - use an RC or ferrite filter between the digital 3.3 V rail and any analog supply domain, per Microchip's ATSAM4CM power supply guidance.
Place current-transformer and voltage-divider metrology sensing inputs away from the MCU's digital switching traces; keep the sampling front-end on a defined analog area of the PCB with a solid ground reference. Route the crystal (for the 120 MHz PLL reference oscillator) with short traces, guard rings, and nearby ground vias. The exposed routing density of a 14x14 mm 100-LQFP at 0.5 mm pitch requires careful fan-out: use 0.2-0.25 mm traces with via-in-fanout escape patterns, and reserve at least one signal layer for unbroken analog returns.
Two frequent pitfalls: (1) assuming any SAM4CM/SAM4C suffix is interchangeable - the -AU (100-LQFP tray) and -CU suffixes denote different packages with different land patterns, so order the exact suffix matching your footprint; (2) underestimating Flash usage - 1 MB must hold metrology firmware plus communication/protocol stacks for both cores; if your dual-core image approaches the limit, plan the same-footprint ATSAM4C32C-AU (2 MB) as a second-source option early. Also verify crypto-key provisioning flow against Microchip's security documentation before locking device fuses.
