About
The GR716A is a radiation-hardened (rad hard) microcontroller featuring a fault-tolerant LEON3 SPARC V8 processor, making it ideally suited for space and other high-reliability applications. It integrates a comprehensive set of communication interfaces and on-chip analog functions, including an Analog-to-Digital Converter (ADC) and Digital-to-Analog Converter (DAC). The device also incorporates essential power management and monitoring features such as Power-on-Reset, an Oscillator, Brown-out detection, and LVDS transceivers. To simplify power supply requirements, it includes regulators that support operation from a single 3.3V supply. Flight parts of the GR716A are available, indicating its readiness for deployment in space missions. The product page also mentions ‘Integrated Analog functions’ and ‘Memory support’ as key features, though specific details for these are not provided in the text. The qualification status for flight parts is also mentioned, with a note that electrical rejects may be delivered in lieu of a dummy package model.
