The Digi Microcontroller Assist™ hardware
The Digi Microcontroller Assist, or MCA, is a small microcontroller that is deeply integrated into the
design of the ConnectCore 8X module. It assists the i.MX 8X processor with advanced operations
related to power management, security, and system reliability. The functionality provided by the MCA
includes:
