6
of on-chip RAM and fewer than 16MB of Flash, significantly
reducing cost and size.
The i.MX RT1060A ("ten-sixty-a"), has a 600MHz Arm™
Cortex-M7™ processor, 1MB of on chip SRAM, an LCD display
interface, camera interface, advanced security, and flexible
communication, combined with a complete turnkey AVS
software solution and a production ready hardware design, to
enable OEMs to quickly and easily add Alexa to their product
designs.
With this solution, device makers realize further benefits of
shorter time to market, and lower development and lifetime
costs. It brings together the Alexa Voice Service, AWS IoT Core,
and Amazon FreeRTOS to provide complete and best-in-class
security, deployment, and device monitoring.
NXP's i.MX RT MCU-based AVS solution is available as a
complete kit for evaluation, development, and prototyping.
The hardware consists of two small, 30mm x 40mm boards.
The MCU system on module (SoM) carries the i.MX RT1060A
processor, 32MB of HyperFlash memory, and a Wi-Fi/Bluetooth
module. The audio board has three (3) MEMS microphones
and connects to a speaker driven by NXP's TFA9894D smart
audio amplifier. The hardware ships with software that includes
everything necessary for a developer to, out-of-the-box,
connect to the Alexa Voice Service and immediately start
prototyping. This one-stop-shop software package includes
far-field voice processing (echo cancellation, noise suppression,
beam forming, barge-in), an Alexa wake word inference engine,
an AVS client application, API, and all necessary drivers.
