The ATSAMV70N20B-AABTV22 from Microchip Technology is a 32-bit microcontroller built on the Arm Cortex-M7 core, part of the SAM V70 family designed for automotive and industrial connectivity. Engineers working on infotainment, audio processing, and networked control systems choose it for its high clock speed, generous on-chip memory, and automotive-grade qualification.
The SAM V70 series runs at clock speeds up to 300 MHz and pairs 1 MB of Flash with 384 kB of SRAM. This device ships in a 100-pin LQFP package for surface-mount assembly and carries RoHS compliance. Here is a closer look at what it offers.
Key Features of the ATSAMV70N20B-AABTV22
High-Performance Arm Cortex-M7 Core
The device runs on a 32-bit Arm Cortex-M7 processor clocked up to 300 MHz. That headroom handles demanding real-time control and signal processing without a separate co-processor.
1 MB Flash and 384 kB SRAM
On-chip memory covers 1 MB of Flash program storage and 384 kB of SRAM. Applications with large codebases and buffered data run without external memory in many designs.
Audio, Ethernet, and USB Connectivity
Integrated interfaces span audio, Ethernet, and USB. This suits connected products that move data between a host, a network, and audio peripherals on a single chip.
Automotive-Grade Qualification
The part meets the AEC-Q100 automotive standard and operates across a temperature range of -40°C to 105°C. It fits cabin, under-hood, and industrial environments where temperature swings are wide.
100-Pin LQFP Surface-Mount Package
The 14 mm by 14 mm 100-pin LQFP package mounts directly to the PCB using standard surface-mount processes. The footprint balances I/O count against board space.
RoHS Compliant
The component is RoHS compliant, so it meets restrictions on hazardous substances for global manufacturing and export.
