GR716B: Mixed-Signal Rad-Hard Microcontroller for Switching Power and Motor Control

The GR716B is a rad-hard and fault-tolerant mixed-signal microcontroller. The GR716B has been developed to provide high computational performance, support for advanced interfaces, several analog functions, possibilities to control switching power applications, and support functionality for supervision and control of SRAM FPGAs in space. The GR716B is currently in development and prototypes will be available in Q1 2024. This paper describes the overall functionality of the device and applications in which the device can be used to control advanced functions. The applications described are DC/DC converter control, motor control and magnetorquer driver control.
