Microchip Technology Inc. has launched the SAMA7G54 ARM Cortex A7 MPU operating at up to 1 GHz. The SAMA7G54 includes a MIPI CSI-2 camera interface and a conventional parallel camera interface, allowing developers to design low-power stereo vision applications with more accurate depth perception.

The company is committed to preserving the low-power MPU portfolio. The new device extends this low-power trend to the 1 GHz performance class of Linux-compatible MPUs by offering flexible low-power modes and voltage and frequency scaling. Combined with its new MCP16502 PMIC, this MPU allows embedded designers to fine-tune their end application for the best power consumption versus performance while optimizing the lowest overall system cost. The MCP16502 is supported by its main Linux distribution for the SAMA7G54. It provides easy entry and exit from available low-power modes and supports dynamic voltage and frequency scaling.

“The SAMA7G54 offers designers a low-risk path to developing power and performance-optimized AI solutions for edge deployment,” said Rod Drake, vice president of the 32-bit MPU business unit at Microchip. “Designers can now build high-performance imaging and audio-centric AI applications without having to use multi-core MPUs with much higher power consumption.”

For audio applications, the device combines enhanced audio features such as four I2S digital audio ports, an eight-microphone network interface, an S/PDIF transmitter and receiver, and a four-channel stereo audio sample rate converter. . It also provides multiple microphone inputs for better source localization to improve the performance of the smart speaker or video conferencing system.

The device also incorporates Arm TrustZone technology with secure boot, secure key storage and cryptography with acceleration and more. Customers can work with the company’s security experts to assess their security requirements and execute the appropriate level of protection for their design.

The company provides hardware and software development support for the device. The SAMA7G54-EK evaluation kit (CPN: EV21H18A) includes connectors and expansion headers for easy customization and quick access to advanced onboard features. Microchip’s mainline Linux distribution supports the device. Bare metal framework and RTOS support are provided in MPLAB® Harmony v3.

Microchip offers a wide range of Ethernet PHYs, switches and hubs, wireless products, and CAN FD transceivers supported by the SAMA7G54.
