This approach takes a proven automotive-qualified device, such as the Atmega64M1, and creates pin-out compatible versions in both high-reliability plastic and space-grade ceramic packages.<\/p>\n<p>The devices are designed to meet radiation tolerances with the following targeted performances:<\/p>\n<p>* Fully immune from Single-Event Latchup (SEL) up to 62 MeV.cm\u00b2\/mg<\/p>\n<p>* No Single-Event Functional Interrupts (SEFI) which secure memory integrity<\/p>\n<p>* Accumulated Total Ionizing Dose (TID) between 20 to 50 Krad(Si)<\/p>\n<p>* Single Event Upset (SEU) haracterization for all functional blocks<\/p>\n<p>The new device joins the AtmegaS128, a radiation-tolerant MCU that has already been designed into several critical space missions including a Mars exploration plus a megaconstellation of several hundred Low Earth Orbit (LEO) satellites.<\/p>\n<p>The COTS version of the device, ATmega64M1, along with its full development toolchain including development kits and code configurator can be used to begin development of hardware, firmware and software.<\/p>\n<p>When the final system is ready for the prototype phase or production, the COTS device can be replaced with the pin-out compatible, radiation-tolerant ATmegaS64M1 in a 32-lead ceramic package (QFP32) with the same functionality as the original device. This leads to significant cost savings while also reducing development time and risk.<\/p>\n<p>The ATmegaS64M1 meets the high operating temperature range of -55\u00b0 C to +125\u00b0 C. It is the first COTS-to-radiation-tolerant MCU to combine a Controller Area Network (CAN) bus, Digital-to-Analogue Converter (DAC) and motor-control capabilities.<\/p>\n<p>These features make it ideal for a variety of subsystems such as remote terminal controllers and data handling functions for satellites, constellations, launchers or critical avionic applications.<\/p>\n<p>To ease the design process and accelerate time to market, <span class=\"highlight highlight-blue\"><a href=\"https:\/\/engineernewsnetwork.com\/blog\/single-wire-serial-eeprom-from-microchip-enables-remote-identification\/\" target=\"_blank\" rel=\"noopener\">Microchip<\/a><\/span> offers the STK 600 complete development board for the ATmegaS64M1, giving designers a head-start to develop code with advanced features for prototyping and testing new designs.<\/p>\n<p>The device is supported by the Atmel Studio Integrated Development Environment (IDE) and software libraries for development and debugging.<\/p>\n<p>The devices are available today for sampling and volume production in four derivatives:<\/p>\n<p>* ATmegaS64M1-KH-E in ceramic prototype QFP32 package<\/p>\n<p>* ATmegaS64M1-KH-MQ, ceramic space-grade QFP32 package, QMLQ qualified<\/p>\n<p>* ATmegaS64M1-KH-SV, ceramic space-grade QFP32 package, QMLV qualified<\/p>\n<p>* ATmegaS64M1-MD-HP in plastic QFP32 package, AQEC high-reliability qualified for volume programme.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Microchip announces a new microcontroller (MCU) that combines specified radiation performance with the low-cost development associated with Commercial Off-The-Shelf (COTS) devices.
