Arm Cortex-M7 SoC Radiation-Hardened Technology-Based SAMRH71 MPU and SAMRH707 MCU for Space Systems

Microchip Technology has introduced the Arm Cortex-M7 SoCradiation-hardened technologyimplemented SAMRH71 Arm-based microprocessor (MPU) and the SAMRH707 microcontroller (MCU). The radiation-hardened SAMRH71 provides a combination of space connectivity interfaces along with high-performance architecture with more than200 Dhrystone MIPS (DMIPS). The SAMRH71’s Arm Cortex-M7 core is coupled withhigh-bandwidth communication interfacessuch as SpaceWire, MIL-STD-1553, CAN FD, and Ethernet with IEEE 1588 Generalized Precision Time Protocol (gPTP) capabilities for offering high-level radiation performance, extreme temperatures, and high reliability.

As an expansion of Microchip’s radiation-hardened Arm Cortex-M7-based MCUs portfolio, the SAMRH707 device provides analog functions on top of a>100 DMIPS processor单位与数字信号Processing (DSP) capabilities, combined withspace connectivity interfaces在一个小足迹为高层拉迪亚而设计的tion performance, extreme temperatures and high reliability. The device comes with a high level of integration embedded Static Random Access Memory (SRAM) and flash memory, high-bandwidth communication interfaces including SpaceWire, MIL-STD-1553, and CAN FD, along with analog functions such as a 12-bit Analog-to-Digital Converter (ADC) and Digital-to-Analog Converter (DAC).

For support and to speed up the system design developers can use the SAMRH71F20-EK and SAMRH707F18-EK evaluation boards. Both the devices are supported by the company’s Integrated Development Environment (IDE) for development.
