Microchip has announced a new microcontroller (MCU) that combines specified radiation performance with low-cost development associated with Commercial Off-The-Shelf (COTS) devices. The ATmegaS64M1 MCU is ideal for aerospace applications that require faster development time and reduced cost.

The ATmegaS64M1 meets the high operating temperature range of -55° C to +125° C. It is the first COTS-to-radiation-tolerant MCU to combine a Controller Area Network (CAN) bus, Digital-to-Analog Converter (DAC) and motor control capabilities. These features make it ideal for a variety of subsystems like remote terminal controllers and data handling functions for satellites, constellations, launchers or critical avionic applications.

The AtmegaS64M1, according to Microchip, uses the company’s COTS-to-radiation-tolerant technique to overcome the problems of high costs and development times associated with space components.

This approach takes a component that is already qualified to automotive standards and seals them in pin-out compatible plastic and ceramic packages to provide space-grade components.

The new device is the firm’s second 8-bit megaAVR MCU after the ATmegaS128 radiation-tolerant MCU that has already been designed into several critical space missions, states the Press release.

“Our COTS-to-radiation-tolerant approach results in a no-compromise, space-grade component and not merely an up-screened or enhanced device that’s targeted to the aerospace industry,” said Patrick Sauvage, director of Microchip’s aerospace business unit. “Developing with a COTS device that can be swapped out for a fully functional high-rel plastic or ceramic equivalent with the same pinout reduces development time, costs and risk for our customers.”

To ease development, Microchip offers the STK 600 complete development board for the ATmegaS64M1. The device is supported by Atmel Studio Integrated Development Environment (IDE) for developing, debugging and software libraries.
