SAMA7G54 Microprocessor from Microchip Technology
The SAMA7G54 is a high-performance, ultra-low-power ARM Cortex-A7 CPU-based 1GHz embedded microprocessor (MPU). This MPU integrates complete higher-performing imaging and audio-centric edge-based AI applications without a multi-core microprocessor. As the first 1GHz single-core MPU with a MIPI CSI-2 camera interface and advanced audio features, the SAMA7G54 allows the development of low-frame rate vision or audio-based AI applications for edge deployment where power consumption is a precious resource, such as automotive driver assistant or stereo vision applications.
Most notably, SAMA7G54 features a massive array of media peripherals and other connectivity. For example, it boasts advanced features such as four digital audio ports with an onboard 4-stereo-channel audio sample rate converter, native Sony/Philips digital interface (S/PDIF) transmit/receive ports and eight microphone inputs. It features an image sensor controller (ITU-R Bt. 601/656 supporting) and up to eight megapixels for still images and video at 60fps in 720p resolution. It also boasts a 2-lane MIPI CIS-2 and 12-bit RGB interface for a variety of image processing applications.
For security, SAMA7G54 features ARM TrustZone, secure boot with onboard key storage, and hardware cryptography, protecting sensitive data from unauthorized access. It also prevents the execution of unauthorized code at startup. SAMA7G54 features an optimized power management solution connection to MCP16501/2 PMICs to allow designers to fine-tune system performance and power consumption for their applications.
