ATSAME70Q20B-AN - 300MHz Cortex-M7 MCU, 1MB Flash | Microchip

The Microchip Technology ATSAME70Q20B-AN is a high-performance 32-bit ARM Cortex-M7 microcontroller with FPU, operating at up to 300 MHz, integrating 1 MB of Flash and 384 KB of SRAM in a 144-pin LQFP (20x20 mm) package. It belongs to the SAM E70 family of flash microcontrollers designed for industrial connectivity, motor control, and graphical HMI applications. A microcontroller (MCU) is a single-chip computer containing a processor core, memory, and programmable peripherals. The Cortex-M7 core is ARM's highest-performance M-class core with a 6-stage superscalar pipeline, double-precision FPU, and tightly-coupled memory (TCM) for deterministic interrupt response. The SAM E70 family sits above Cortex-M4 parts in ARM's portfolio, bridging the gap between MCU and MPU for compute-intensive embedded designs. Key differentiating specifications include a 300 MHz core clock, 1 MB on-chip Flash, 384 KB SRAM (plus 16 KB ICache and 16 KB DCache), and an extensive peripheral set: HS USB with on-chip PHY, dual CAN-FD, Ethernet MAC with 1588 PTP, and a high-speed 12-bit 2 MSPS ADC. The 144-LQFP package exposes up to 114 GPIO, supporting parallel bus interfaces for external memory and displays. Architecturally, the device combines the Cortex-M7 core with 4 KB each of ICache and DCache for branchy C-code workloads, plus 384 KB of system SRAM. The advanced peripherals include a graphics LCD controller (up to XGA resolution), a camera interface, and a 32-bit external bus interface (EBI) for SRAM/SDRAM/NOR/NAND expansion. A single 1.2 V internal LDO and 3.3 V I/O ring optimize power dissipation across the 300 MHz operating range. Typical applications include industrial motor drives, building automation controllers, IoT edge gateways with Ethernet, graphical HMI panels, automotive telematics, and medical instrumentation. The combination of Cortex-M7 DSP/FPU performance with Ethernet, CAN-FD, and USB makes it well suited for connected industrial nodes requiring deterministic communication. When designing with the ATSAME70Q20B-AN, ensure the 3.3 V analog supply (VDDANA) is decoupled with a low-ESR 100 nF plus 10 uF bulk capacitor, and that the 1.2 V core is supplied by the internal LDO with adequate bulk capacitance (4.7 uF + 100 nF) on VDDOUT. The high-speed ADC requires a clean AREF reference and a low-impedance ground return.

ATSAME70Q20B-ANT

ATSAME70Q20B-ANT - 300MHz Cortex-M7 MCU 1MB Flash LQFP-144

The Microchip ATSAME70Q20B-ANT is a 32-bit ARM Cortex-M7 microcontroller with FPU operating up to 300 MHz, featuring 1 MB of Flash and 384 KB of SRAM in a 144-pin LQFP (20x20 mm) package. Designed for high-performance embedded applications, it integrates a 16-bit external data bus with a 24-bit address bus, multiple PWM channels, ADC, DMA, and DAC peripherals. The device operates across an industrial temperature range of -40C to +105C from a nominal 1.2V core supply. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program memory (Flash), data memory (SRAM), and a rich set of peripherals on one silicon die. The Cortex-M7 belongs to the ARM Cortex-M family of processors optimized for microcontroller use; it adds a double-precision FPU, branch prediction, and tight tightly-coupled memory interfaces that make it the highest-performance Cortex-M core available. Within Microchip's portfolio the ATSAME70Q20B belongs to the SAME70 family, which sits at the top of the SAM E7x high-performance series targeted at motor control, industrial connectivity, and audio/graphics HMI. Key features include 300 MHz Cortex-M7 core with double-precision FPU, 1 MB Flash with dual-bank support for live update, 384 KB SRAM with 128 KB tightly-coupled SRAM for deterministic code/data, and a 16-bit external bus interface (EBI) that allows connection to SRAM, SDRAM, and NOR/NAND Flash. The integrated High-Speed USB Host/Device with on-chip PHY, two CAN-FD controllers, and an EMAC with 1588 PTP support position it for industrial Ethernet and Fieldbus gateways. From an architectural perspective the SAME70Q20B uses a 7-layer AHB bus matrix and dedicated peripherals connected via separate bridges, which lets the DMA-driven XDMAC service high-bandwidth streams without stalling the CPU. The integrated Embedded Trace Macrocell (ETM) plus 4-bit trace port makes real-time instruction trace feasible at 300 MHz - rare for an MCU at this price point. Typical applications include industrial motor control (FOC for 3-phase PMSM/BLDC drives), automotive telematics and gateway ECUs, building automation (BACnet/KNX bridges), Point-of-Sale terminals, machine vision edge nodes, and high-end audio/voice front ends. Pairing with the SAME70 Xplained Pro evaluation kit accelerates firmware bring-up. When designing with the ATSAME70Q20B-ANT, pay attention to the 1.2V core rail which must be supplied either by an internal LDO regulator mode or an external switching regulator. Decoupling the VDDCORE pin with 100 nF + 4.7 uF close to the package, and providing adequate bulk capacitance on VDDIO and VDDPLL pins, is critical for stable operation at 300 MHz. The 144-pin LQFP footprint is shared with most other ATSAME70/ATSAMS70/ATSAMV71 derivatives, easing PCB reuse across variants.
