ATSAM4SD16CA-AN - 120MHz Cortex-M4 MCU, 1MB Flash | Microchip
MPN: ATSAM4SD16CA-AN ✓ AktifATSAM4SD16CA-AN Ringkasan
Key features include 2x512KB dual-bank Flash supporting safe in-application programming, a 16-bit ADC, 12-bit DAC, multiple UART/USART, SPI, I2C, USB 2.0 Full-Speed, CAN, and an External Bus Interface (EBI) for SRAM/NOR/NAND memories. The device also integrates a cryptographic accelerator and a true random number generator (TRNG), enabling hardware-accelerated AES, SHA, and secure key storage for IoT and connected-device designs. An Event System and Peripheral DMA Controller minimize CPU load by handling data movement autonomously.
The ATSAM4SD16CA-AN uses a Cortex-M4 core with single-precision floating-point unit and DSP extensions, achieving 1.25 DMIPS/MHz (Dhrystone 2.1) and supporting the full ARM Cortex Microcontroller Software Interface Standard (CMSIS). The 100-pin LQFP package exposes the full set of peripherals while remaining manufacturable with standard 4-layer PCB processes, making it well suited for prototyping through volume production.
Typical applications include industrial control and HMI, building automation, smart energy metering, USB peripherals, motor control (BLDC/PMSM), and connected IoT edge nodes with secure communications. The 120 MHz speed and DSP instructions also support audio processing, sensor fusion, and protocol stacks requiring real-time computation.
When designing with this part, allocate careful PCB real estate for decoupling: place 100 nF X7R capacitors near each VDD pin pair and a bulk 4.7 uF capacitor on the main 3.3V rail. The exposed-pad variant of LQFP must be soldered to a thermal pad for proper heat dissipation and ground integrity. Plan Flash bank layout carefully when implementing dual-bank firmware updates.

Industrial Control and HMI
The ATSAM4SD16CA-AN's 120 MHz Cortex-M4 core with FPU and DSP instructions handles real-time PID loops, machine vision pre-processing, and multi-axis motor coordination in industrial PLCs and CNC machines. Its 1 MB dual-bank Flash supports complex ladder-logic or IEC 61131-3 runtimes, while 160 KB SRAM holds sensor data buffers without external memory. The wide 1.62-3.6V supply and -40C to +85C industrial grade allow deployment in factory cabinets. USB Full-Speed and CAN connectivity integrate with operator panels and industrial fieldbuses. Hardware AES/SHA/TRNG accelerates secure OPC UA or Modbus-TCP communications.

Motor Control (BLDC / PMSM)
Field-oriented control (FOC) of three-phase BLDC and PMSM motors demands deterministic PWM timing and fast current-loop math. The ATSAM4SD16CA-AN delivers this through its 16-bit PWM controller with hardware dead-time insertion, 12-bit ADC synchronized to PWM edges, and Cortex-M4 DSP instructions running Clarke/Park transforms and SVPWM at full 120 MHz. Hardware Q31 math eliminates fixed-point overflow risk. The Event System routes ADC end-of-conversion to DMA for jitter-free sampling, while CAN and UART provide the industrial feedback channel for servo drives.

Building automation hubs (BACnet, KNX, DALI gateways) run multiple protocol stacks simultaneously while serving touch-screen HMI and cloud uplinks. The ATSAM4SD16CA-AN's 1 MB Flash stores BACnet/KNX/DALI stacks plus application logic, while 160 KB SRAM holds TCP/TLS buffers for cloud MQTT connections. Dual-bank Flash enables fail-safe OTA upgrades critical for deployed building systems. RS-485 UART, CAN, and SPI peripherals connect to sensor networks; the hardware AES engine secures TLS sessions to cloud services.

Catatan Desain
Place a 100 nF X7R 0402 decoupling capacitor within 2 mm of every VDDIO/VDDIN pin pair. Add a single 4.7 uF X5R bulk capacitor on the main 3.3V rail near the VDDIN pin. The 32.768 kHz low-frequency crystal (XIN/XOUT, pins 95-96) requires a load capacitor pair matched to the crystal's CL specification (typically 12-18 pF); keep traces short and guard the crystal with a ground ring to reduce EMI.
At full 120 MHz operation with all peripherals active, the ATSAM4SD16CA-AN typically dissipates ~150 mW. The 100-LQFP package has theta_JA of approximately 50 C/W, yielding a 7.5 C rise above ambient - well within the -40C to +85C industrial range. Estimated: at ambient 70 C the junction reaches ~78 C. For high-temperature environments above 70 C ambient, add thermal vias under the center pad ground connection.
The ATSAM4SD16CA-AN's NRST pin (pin 97) is bidirectional; in noisy environments add an external 10 kohm pull-up and 100 nF capacitor to ground for a robust reset. Do not enable the USB controller without first configuring the 3.3V USB transceiver supply (UVBUS pin) - leaving it floating can cause latch-up. When using dual-bank Flash for IAP, ensure your linker script places the bootloader in bank 0 with a lockable write-protect region.
Informasi Konformitas
RoHS compliant and lead-free per Microchip product page. Industrial temperature grade (-40C to +85C). MSL Level 3 - moisture handling required per IPC/JEDEC J-STD-033 after opening MBB. Not AEC-Q100 qualified; for automotive designs use ATSAM4S46C44 or SAM V71 family.
