Single-core MPU integrates MIPI CSI-2 camera interface

Microchip Technology Inc. has claimed the first single-core microprocessor with a MIPI CSI-2 camera interface and advanced audio features with the launch of the SAMA7G54 Arm Cortex A7-based MPU running up to 1 GHz. The ultra-low-power single-core MPU includes both a MIPI CSI-2 camera interface (supporting up to 8 megapixels) and a traditional parallel camera interface to support low-power stereo vision applications with more accurate depth perception, said the company.

Offering higher performing peripherals without sacrificing power consumption, the new MPU addresses the pain point of having to use higher performing multi-core MPUs for AI solutions that require advanced imaging and audio capabilities that consume much higher power. The SAMA7G54 embedded processor extends Microchip’s low-power trend into the 1-GHz performance class of Linux-capable MPUs by providing low-power modes to reduce power consumption, as well as voltage and frequency scaling.

In addition, when the SAMA7G54 is combined with Microchip’s new MCP16502 power management IC (PMIC), the solution “enables embedded designer to fine-tune their end application for the overall best power consumption versus performance, while also optimizing for the lowest overall system cost,” said Microchip. The company also offers Ethernet PHYs, switches and hubs, wireless products, and CAN FD transceivers that are supported by the SAMA7G54.

Enhanced audio features include four I2S digital audio ports, an 8-microphone array interface, an S/PDIF transmitter and receiver, as well as a four stereo channel audio sample rate converter. It also integrates multiple microphone inputs for improved source localization in smart speaker or video conferencing systems.

Other features include support for multiple memory devices including 16-bit DDR2, DDR3, DDR3L, LPDDR2, LPDDR3 with flexible boot options from octal/quad SPI, SD/eMMC as well as 8-bit SLC/MLC NAND Flash, and connectivity options such as dual Ethernet (one Gigabit Ethernet and one 10/100 Ethernet), six CAN-FD, and three high-speed USB. Security features include the Arm TrustZone technology with secure boot, secure key storage, and cryptography with acceleration.

Microchip provides both hardware and software development support for the SAMA7G54. The SAMA7G54-EK Evaluation Kit (CPN: EV21H18A) features connectors and expansion headers for customization and quick access to embedded features. The device is supported by Microchip’s mainline Linux distribution and bare-metal framework and RTOS support is provided within MPLAB Harmony v3.
