Product details

300 MHz Cortex-M7 with 2 MB Flash — what it buys you

The ATSAME70Q21A-CN uses an ARM Cortex-M7 core clocked at 300 MHz.

Peripheral set for industrial gateway and motor control

Connectivity includes an integrated Ethernet MAC, dual CANbus controllers, USB host/device, and a QSPI interface.

144-ball LFBGA — layout and rework notes

The part comes in a 144-ball LFBGA with a 10x10 mm body.

The ATSAME70Q21A-CN operates from 1.62 V to 3.6 V on the Vcc/Vdd rail.

The SAM E70 family is a current product offering.

Frequently asked questions

Does ATSAME70Q21A-CN have an integrated Ethernet MAC?

Yes, the ATSAME70Q21A-CN includes an integrated 10/100 Ethernet MAC controller accessible via RMII or MII interface. You still need an external PHY transceiver chip.

What is the maximum clock speed of ATSAME70Q21A-CN?

The ARM Cortex-M7 core runs at a maximum clock speed of 300 MHz. This is the highest core frequency in the SAM E70 series.

What is the difference between ATSAME70Q21A-CN and ATSAME70Q21A-AN?

The suffix indicates the operating temperature range. All other specifications — 300 MHz core, 2 MB Flash, 384 KB SRAM, 144-LFBGA package — are identical between the two suffixes.

Is ATSAME70Q21A-CN compatible with the SAM E70 Xplained board?

Yes, the ATSAME70Q21A-CN is the MCU fitted on Microchip's SAM E70 Xplained evaluation board (ATSAME70-XPLD). The board provides a reference design for the 144-LFBGA package and peripheral connections.
