MPN: ATSAME70Q21B-AN ✓ AktifATSAME70Q21B-AN Ringkasan
An MCU (Microcontroller Unit) is a single-chip computer that integrates a CPU core, memory, and programmable peripherals. The Cortex-M7 class is ARM's highest-performance microcontroller core, featuring a 6-stage pipeline, superscalar dual-issue execution, hardware FPU, and tightly-coupled memories for deterministic latency. Compared to Cortex-M4 parts, Cortex-M7 devices offer roughly 2x DMIPS performance, an enhanced SIMD instruction set, and an L1 cache, making them suitable for advanced signal processing and graphics applications.
Key features of the ATSAME70Q21B-AN include: 300 MHz core clock, 2 MB embedded Flash, 384 KB SRAM with ECC, 16-bit External Bus Interface (EBI) supporting SDRAM, High-Speed USB Host/Device with on-chip PHY, dual CAN-FD controllers, Ethernet MAC (GMAC) with 1588 PTP, 12-bit 2 MSPS ADC, and image sensor interface. Security features include a True Random Number Generator (TRNG), hardware AES, secure boot, and flash tamper detection. The peripheral set is interconnected via AHB/APB matrix for low-latency DMA access.
The device integrates a multi-layer bus matrix with two DMA controllers (16 channels total) and dual ports, allowing concurrent CPU and data transfer operations without contention. Its SmartMem peripherals include eMMC/SD card interface, NAND Flash controller with ECC, and SDRAM controller. The Event System enables hardware-triggered peripheral cooperation without CPU intervention, improving real-time deterministic behavior.
Typical applications include industrial motor control (FOC for PMSM/BLDC drives), grid protection and smart energy metering, automotive body and infotainment subsystems, high-end audio processing (up to 192 kHz 24-bit codecs), industrial Ethernet nodes with EtherCAT or Profinet support, point-of-sale terminals, and medical diagnostic imaging front-ends. The wide peripheral mix also suits self-contained additive-manufacturing controllers and surveillance DVR systems.
When designing with the ATSAME70Q21B-AN, ensure robust VDDCORE decoupling with 100 nF + 4.7 µF ceramic capacitors per the reference schematic design guide, since high-frequency CPU transitions demand low-impedance power delivery. Plan the PCB for the 20x20 mm LQFP footprint with multiple GND return paths and keep the high-speed USB traces 90 ohms differential-impedance matched.

Aplikasi Umum
ATSAME70Q21B-AN cocok untuk 6 aplikasis: Industrial Motor Control (FOC), Industrial Ethernet / IIoT Gateway, High-End Audio Processing, Automotive Infotainment HMI, Smart Grid Energy Metering, Surveillance DVR / NVR Edge.
Industrial Motor Control (FOC)
The ATSAME70Q21B-AN is purpose-built for sensorless and sensored Field-Oriented Control of PMSM and BLDC motors. Its Cortex-M7 FPU and DSP extensions accelerate Park/Clarke transforms, while two 2 MSPS 12-bit ADCs simultaneously sample phase currents for closed-loop bandwidth above 20 kHz. Built-in position-sensor timers and the Quadrature Decoder interface read Hall sensors or incremental encoders without inline decoders, simplifying firmware and reducing latency. The 384 KB SRAM accommodates ripple-free FOC state buffers and observer algorithms, while Ethernet/CAN-FD connectivity enables real-time EtherCAT/CANopen integration into industrial servo systems.

Industrial Ethernet / IIoT Gateway
The ATSAME70Q21B-AN integrates a 10/100 Ethernet MAC with IEEE 1588 PTP hardware timestamping, ideal for Profinet, EtherCAT slave or Modbus-TCP industrial nodes. Its dual CAN-FD controllers bridge to legacy automotive/fieldbus networks, while the GMAC and XDMAC offload protocol stacks so the Cortex-M7 focuses on application logic. The 2 MB Flash fits full TCP/IP + TLS libraries plus a web management UI, and 384 KB SRAM sustains packet buffers and TLS handshake state. The LQFP-144 footprint provides 5V-tolerant GPIO for direct connection to industrial sensor rails without inline transceivers.

High-End Audio Processing
The ATSAME70Q21B-AN's Cortex-M7 DSP engine can run software codecs and effects up to 192 kHz / 24-bit per channel for digital mixer oscillators. Its double-precision FPU preserves audio dynamic range through cascaded biquad filters and FFT-based spectrum analysers without clipping artifacts. The SSC/I2S interfaces connect directly to audio DACs such as the AKM4621EF, while the 2 MB Flash stores multitrack loops and the 384 KB SRAM acts as an effect line ring buffer. The integrated HS USB enables class-compliant UAC2 audio streaming to host PCs at 480 Mbps.

Automotive Infotainment HMI
The ATSAME70Q21B-AN drives TFT LCD displays up to XGA resolution via the Image Sensor Interface (ISI) and external memory bus, suiting digital instrument clusters and infotainment HMIs. Its MIPI with multi-layer bus matrix renders instrument-cluster graphics with minimal CPU overhead, while the HS USB supports smartphone projection protocols. The integrated hardware AES and TRNG enable secure over-the-air firmware updates. Designers select ATSAME70Q21B-AAB variants for AEC-Q100 Grade 2 compliance in the same LQFP-144 footprint to bypass PCB rework on automotive-grade SKUs.

Smart Grid Energy Metering
The ATSAME70Q21B-AN's dual 2 MSPS ADCs synchronously capture line voltages and currents, while the Cortex-M7 DSP library computes 12-bit/24-bit harmonic analysis up to the 63rd harmonic in real time. The TRNG and hardware AES secure the meter's cryptographic keys for signed billing data, and the integrated GMAC transports DLMS/COSEM or IEC 61850 frames to concentrators. The wide operating temperature range supports outdoor cabinet installations, while 2 MB Flash stores calibration tables and signed firmware images with rollback protection.

Surveillance DVR / NVR Edge
The ATSAME70Q21B-AN's Image Sensor Interface streams up to 720p video from parallel CMOS sensors, while the Cortex-M7 runs H.264 baseline encoding in software at CIF/VGA resolutions, suiting edge NVR or single-channel DVR designs. The HS USB enables webcam-class streaming at 480 Mbps, and the SD/eMMC interface stores local recordings. The 384 KB SRAM holds reference frames plus compressed bitstream buffers; security-critical applications benefit from the integrated TRNG and hardware AES for video stream encryption.

Diferensiator Kunci
- Highest on-chip SRAM in 144-pin SAM E70 family at this price point (vsATSAME70Q20B-AN)
- Largest integrated Flash (32 MB vs 16 MB for SAM S70 base) (vsATSAMS70Q21B-AN)
- On-chip HS USB PHY eliminates external ULPI transceiver cost (vsR7FA6M5AH3CFC)
- DSP and double-precision FPU accelerate motor-control algorithms (vsR7FA6M5AH3CFC)
Catatan Desain
Estimated: The ATSAME70Q21B-AN requires two supplies: VDDCORE at 1.2 V (up to ~150 mA in active mode at 300 MHz, plus 1.8 V/3.3 V VDDIO). The reference design recommends a buck converter such as AP63205WU-7 for VDDCORE, plus 100 nF + 4.7 µF X7R ceramic decoupling within 5 mm of every VDDIO/VSS pin pair. The VDDBU backup supply must be present whenever the RTC32K oscillator is used; tie it to VDDIO if RTC is not required.
The 20 x 20 mm LQFP-144 footprint has 0.5 mm pitch and 144 I/O plus multiple power/ground pads - plan a 4-layer PCB with dedicated ground plane. Keep high-speed USB DP/DM traces 90 ohms differential and length-matched within 150 mil. Place the 12 MHz main crystal traces short, symmetric, and guard-traced with ground to minimise clock harmonic radiation into the ADC sampling bandwidth.
Do not attempt to use the ATSAME70Q21A-CNT silicon revision interchangeably with the ATSAME70Q21B-AN 'B' revision in production firmware builds without re-checking errata. Rev B added a fix for USB HS PHY errata and revised power-on reset thresholds. Also, avoid using the backup domain VDDBU when the RTC is unused - tie it to VDDIO through a ferrite bead and local decoupling to prevent leakage and brown-out glitches.
Estimated: At 300 MHz active mode, the ATSAME70Q21B-AN core power is approximately 1.4 W. With a 4-layer PCB and minimum copper pour, theta_JA is ~35 C/W, yielding a 49 C junction temperature rise above ambient. At an industrial-grade +85 C ambient this leaves only 15 C margin to the +105 C operating limit, so route substantial GND copper pours and thermal vias under the exposed die pad pattern to maintain derating headroom.
