ATSAM4CMP16CB-AUR - Dual-Core 120MHz 1MB MCU | Microchip
MPN: ATSAM4CMP16CB-AUR ✓ فعالATSAM4CMP16CB-AUR جائزہ
A microcontroller unit (MCU) is a single-chip embedded computer that integrates a processor core, memory, and configurable peripherals onto one die, forming the lowest tier of the compute hierarchy: core -> microcontroller -> embedded system. The SAM4CM family extends Microchip's (formerly Atmel) SAM4 ARM-based MCU portfolio, and this variant targets smart metering.
Key features include the dual-core architecture pairing a Cortex-M4F with hardware FPU for application processing and metering computation, 1 MB of on-chip FLASH for application and firmware storage, and an integrated hardware crypto engine (CRYPTO, per Mouser listing). The device provides 52 general-purpose I/O pins and connectivity peripherals including EBI/EMI external bus, I2C, IrDA, SPI, and UART/USART, enabling flexible interfacing to meters, displays, and communication modules.
Technical depth: Microchip positions the SAM4CMP16 as a system-on-chip solution for residential and poly-phase metering applications achieving up to class 0.2 metrology accuracy over a dynamic range of 3000:1, with seven metering channels and industrial temperature range support. The dual-core split allows real-time metrology sampling to run deterministically on one core while the other manages protocol stacks, LCD driving, and user interfaces without mutual interference.
Typical applications include residential electricity meters, poly-phase industrial meters, and smart-grid nodes that require certified measurement accuracy plus secure data handling. The hardware cryptography block supports secure firmware and data protection demanded by utility deployments.
Design consideration: this device combines 1.2V core and 3.3V I/O domains, so power-tree sequencing and decoupling must follow the manufacturer datasheet recommendations; the 100-LQFP 14x14 mm footprint requires careful high-frequency layout around the crystal and analog metrology front-end.

عام استعمالات
ATSAM4CMP16CB-AUR کے لیے موزوں ہے 6 ایپلیکیشنs: Poly-Phase Industrial Electricity Meters, Residential Smart Meters (AMI), Data Concentrators and Smart-Grid Nodes, Industrial Power Quality Analyzers, Secure Embedded Controllers with Cryptographic Storage, Streetlight and Load-Control Terminals.
Poly-Phase Industrial Electricity Meters
The ATSAM4CMP16CB-AUR fits poly-phase industrial electricity metering because its integrated 7-channel metering engine delivers class 0.2 accuracy across a 3000:1 dynamic range, per Microchip's product page. In a three-phase meter, voltage and current channels are sampled by the dedicated metrology front-end while one Cortex-M4F core runs the measurement computation in real time; the second core independently handles protocol stacks such as DLMS/COSEM over UART/USART or I2C. This partitioning prevents communication bursts from introducing jitter into the sampling pipeline. The 3.3 V I/O domain connects directly to relay drivers and LCD interfaces, and the hardware crypto engine protects billing data, a common regulatory requirement for revenue meters.

Residential Smart Meters (AMI)
For residential smart meters in advanced metering infrastructure (AMI) networks, the ATSAM4CMP16CB-AUR provides certified measurement accuracy plus the connectivity needed for utility communication. Its UART/USART, I2C, and SPI peripherals interface to RF modules, PLC modems, and head-end displays, while 1 MB of FLASH retains application code, calibration tables, and load-profile logs without external memory. The hardware crypto block supports secure credential storage and authenticated firmware updates demanded by utility security standards. The industrial temperature rating of the UR-grade part covers outdoor meter cabinets, and the dual-core architecture keeps the real-time measurement loop isolated from network stack processing, preserving measurement integrity during burst transmissions.

Data Concentrators and Smart-Grid Nodes
In smart-grid data concentrators, the ATSAM4CMP16CB-AUR aggregates readings from multiple meters via EBI/EMI-connected memory for buffering and its multiple UART/USART ports for communication links. The dual-core 120 MHz Cortex-M4F delivers enough throughput to run parsing, storage management, and uplink protocols concurrently, while the 1 MB FLASH hosts large firmware images including security stacks. The EBI/EMI external bus interface expands RAM for buffer pools when many meters report simultaneously. Hardware crypto accelerates TLS-class authentication of uplink traffic. Its industrial temperature range and 100-LQFP surface-mount package suit dense, fanless grid-side hardware requiring reliable long-life operation in uncontrolled environments.

Industrial Power Quality Analyzers
Power quality analyzers benefit from the ATSAM4CMP16CB-AUR's 7-channel metrology engine and 3000:1 dynamic range, which resolve both light-load and overload conditions without gain ranging. The dual-core split assigns harmonic and RMS computation to the measurement core while the second core drives the user interface, data logging to SPI or EBI-connected memory, and export over UART/USART to SCADA systems. The hardware FPU on the Cortex-M4F accelerates the DSP-style arithmetic used in THD and sag/swell analysis. With class 0.2 accuracy over the full dynamic range, the device supports measurement paths that would otherwise require a dedicated metrology ASIC plus a separate applications MCU, reducing BOM count and board area.

Secure Embedded Controllers with Cryptographic Storage
General-purpose secure controllers that do not need metering can still exploit the ATSAM4CMP16CB-AUR's CRYPTO hardware block, 1 MB FLASH, and dual-core architecture. Typical roles include payment-terminal peripherals, secure logging nodes, and access-control panels where keys and transaction data must never traverse external buses in plaintext. The 52 GPIO pins interface keypads, secure elements over I2C, and displays, while SPI and UART/USART link to host systems. If metering functionality is unnecessary, the pin-compatible SAM4C family member ATSAM4C16CB-AU offers the same dual-core Cortex-M4F platform and 100-LQFP footprint without the dedicated metering front-end, letting designers right-size cost across a shared PCB platform.

Streetlight and Load-Control Terminals
Streetlight controllers and load-management terminals use the ATSAM4CMP16CB-AUR where energy measurement is bundled with control logic. The metering engine meters consumed energy for billing or demand-response accounting at class 0.2 accuracy, while the Cortex-M4F cores run scheduling, communication with head-end systems over UART/USART or I2C, and relay control through GPIO. The 1 MB FLASH stores schedules, tariff tables, and log data across power interruptions, and the crypto block authenticates remote command traffic. The industrial temperature rating and LQFP-100 surface-mount package withstand outdoor cabinet environments, and single-firmware maintainability across meter and controller product variants reduces qualification effort for multi-product fleets.

ڈیزائن نوٹس
The SAM4CM family uses a 1.2 V core domain and a 3.3 V I/O domain, per the 1.2V/3.3V supply notation in distributor listings. Provide a clean 1.2 V core regulator with local decoupling (100 nF per VDD pair plus 10 uF bulk) and sequence the 1.2 V rail per the datasheet power-up requirements to avoid latch-up during startup. Estimated: at 120 MHz full-speed operation the core draws on the order of tens of mA, so regulator thermal design is straightforward, but brown-out thresholds should be enabled to protect FLASH write operations during utility power disturbances common in metering environments.
The 14x14 mm 100-LQFP has 0.5 mm pin pitch; route the analog metrology inputs as short as possible and keep them physically separated from the 120 MHz digital clock tree and EBI/EMI bus to preserve the class 0.2 accuracy budget. Use a solid ground plane under the analog section and a star or guarded ground return for the voltage/current sense channels. Place crystal load capacitors within 2 mm of the oscillator pins. High-current relay or communication transceiver traces must not run beneath or adjacent to the analog sense nets on adjacent layers without a ground shield.
Do not assume the CMS (single-phase) and CMP (poly-phase) parts are interchangeable without reviewing the metrology channel count - the P variant provides 7 channels while the S variant does not, despite identical footprints and flash sizes in the 16 CB grade. Also note the -AUR suffix means tape-and-reel industrial grade; ordering the -AU tray variant for an automated line requires manual feeding. Confirm which metering engine variant your calibration procedures and firmware assume before substituting family members during shortages.
