ATSAM3N2CA-CU - 48MHz Cortex-M3 128KB MCU | Microchip
MPN: ATSAM3N2CA-CU ✗ انتهى عمره الإنتاجيATSAM3N2CA-CU نظرة عامة
A microcontroller is a programmable semiconductor that executes firmware, coordinates digital interfaces, reads sensors, controls actuators, and manages system timing. The ATSAM3N2CA-CU hierarchy is microcontroller -> embedded Flash MCU -> ARM Cortex-M3 MCU -> SAM3N family. Its 48 MHz operating speed provides a practical balance between processing capacity and system complexity for embedded control, while 128 KB of Flash stores application firmware and 16 KB of SRAM supports working data and stack operations.
The verified data identifies an ARM Cortex-M3 revision 2.0 core, Thumb-2 instruction support, a 24-bit SysTick counter, and a Nested Vector Interrupt Controller. These features support efficient event handling, deterministic interrupt-driven designs, and compact embedded software. The listed operating supply range from another verified distributor result is 1.62 V to 3.6 V, although the manufacturer datasheet should be used to verify all electrical limits, pin functions, power sequencing, and peripheral characteristics before design release.
Typical uses include industrial control, sensor acquisition, communications equipment, data acquisition, embedded automation, and compact consumer or instrumentation products. The 79 available I/O positions can support digital control lines, serial interfaces, analog functions, timers, and external peripherals where the selected package pinout permits them. Compared with a discrete processor implementation, an integrated MCU consolidates memory, interrupt handling, and peripherals into one component, reducing board complexity.
The primary design consideration is exact package verification. Because the supplied web results contain conflicting 100-TFBGA and 100-TQFP descriptions, engineers should confirm the ordered package suffix, land pattern, pin assignments, exposed-pad requirements, and PCB footprint directly with Microchip documentation. This page consolidates distributor specifications, package ambiguity, sourcing information, and practical engineering cautions rather than presenting unverified assumptions as datasheet facts.

التطبيقات النموذجية
ATSAM3N2CA-CU مناسب لـ 6 التطبيقs: Industrial Embedded Control, Sensor Acquisition and Data Logging, Communications Equipment, Compact Automation and Motor-Control Support, Instrumentation and Test Systems, Embedded HMI and Control Panels.
Industrial Embedded Control
The ATSAM3N2CA-CU fits industrial embedded-control modules that coordinate sensors, digital inputs, actuators, and communications. Its 48 MHz ARM Cortex-M3 core supports responsive interrupt-driven control, while 128 KB Flash and 16 KB SRAM provide room for application logic and working state. The 79 I/O count can serve multiple interfaces and control lines, but the exact functions depend on the confirmed 100-pin package pinout. Engineers should verify peripheral multiplexing and supply requirements before assigning external hardware.
موصى به
Sensor Acquisition and Data Logging
Use the ATSAM3N2CA-CU in measurement systems that collect sensor data and transfer it through a communications interface. The Cortex-M3 processor handles firmware, sampling sequencing, and data processing at up to 48 MHz, while 16 KB SRAM supports buffers and acquisition state. Interrupt-driven designs can use the Nested Vector Interrupt Controller and SysTick timer for periodic acquisition. Exact analog support, communication peripherals, pin multiplexing, and ADC specifications require the manufacturer datasheet.
موصى به
Communications Equipment
ATSAM3N2CA-CU is suitable as the supervisory controller in communications equipment where firmware must manage user interfaces, status indicators, configuration storage, and external communication devices. Its 32-bit architecture and 48 MHz clock support protocol handling and event-driven control, while 128 KB Flash provides storage for application code. The available evidence does not specify UART, USB, CAN, Ethernet, or other peripheral variants, so interface selection must be confirmed against the exact device documentation and package pinout.
موصى به
Compact Automation and Motor-Control Support
The ATSAM3N2CA-CU can serve as a controller in compact automation equipment where timing, digital I/O, and embedded decision logic matter more than a high-end processor. Its Cortex-M3 core and SysTick support provide a foundation for deterministic task scheduling, while 79 I/O positions can expand connectivity to sensors, drivers, and status devices. Motor-drive performance cannot be inferred from the supplied data because PWM channels, timers, analog functions, and electrical limits are not specified; validate those features in the manufacturer datasheet.
موصى به
Instrumentation and Test Systems
The ATSAM3N2CA-CU is suitable for instrumentation front ends that coordinate measurements, calibration, front-panel controls, and data transfer. Its 48 MHz processing rate supports moderate control-loop and protocol workloads, and its 128 KB Flash accommodates firmware modules without external program memory. For precision analog measurement, verify the exact ADC, reference, amplifier, trigger, and timing capabilities rather than assuming them from the CPU frequency. Package pinout, decoupling, grounding, and exposed-pad requirements are also essential.
موصى به
Embedded HMI and Control Panels
The ATSAM3N2CA-CU can manage compact human-machine interfaces that coordinate buttons, indicators, displays, and embedded control logic. The 79 I/O count may provide enough external signal paths for a panel controller, while 128 KB Flash stores interface and application firmware. The supplied data does not confirm display controllers or specific communication peripherals, so designers should verify signal timing, pin multiplexing, voltage levels, and interface electrical requirements. Firmware should also include debounce, watchdog, and fault-handling strategies after device confirmation.

ملاحظات التصميم
Resolve the package conflict before layout. The verified sources describe ATSAM3N2CA-CU as 100-TFBGA (9x9), while another result identifies 100-TQFP; these are not interchangeable land patterns. Download the current manufacturer package drawing and pin table, confirm the exposed-pad or thermal-pad requirement, and verify every power and ground connection before placing the symbol or routing the board.
Use the verified 1.62 V to 3.6 V supply indication as a design lead, not as a substitute for the complete electrical limits. Confirm operating conditions, I/O voltage thresholds, current consumption, startup behavior, and clock requirements in the manufacturer datasheet. Place regulator and decoupling connections according to the confirmed pinout, and account for ground-current return paths in the high-pin-count package.
Treat all peripheral assignments as unverified until the exact package pin table is available. A related SAM3 part may share a family name while differing in multiplexed functions, memory, timers, communications, or pin availability. Review signal levels, alternate-function selection, interrupt routing, and startup states before assigning external buses or connectors. Prototype-level firmware testing should include reset, brownout, and unused-pin behavior.
معلومات الامتثال
