VA41620 Radiation-Hardened ARM Cortex-M4 Microcontroller
VORAGO Technologies
The VORAGO VA41620 is a radiation-hardened, high-performance 32-bit microcontroller built on an ARM Cortex-M4 core with single-precision Floating Point Unit (FPU), manufactured using VORAGO’s patented HARDSIL technology. Designed for mission-critical spaceborne systems, the VA41620 delivers best-in-class radiation immunity — exceeding 300 krad(Si) Total Ionizing Dose and latch-up immunity above 110 MeV·cm²/mg — making it suitable […]

About
The VORAGO VA41620 is a radiation-hardened, high-performance 32-bit microcontroller built on an ARM Cortex-M4 core with single-precision Floating Point Unit (FPU), manufactured using VORAGO’s patented HARDSIL technology. Designed for mission-critical spaceborne systems, the VA41620 delivers best-in-class radiation immunity — exceeding 300 krad(Si) Total Ionizing Dose and latch-up immunity above 110 MeV·cm²/mg — making it suitable for GEO, MEO, and deep-space missions with long operational lifetimes.
The device integrates 64 KB of on-chip data SRAM and 256 KB of program SRAM, both protected by EDAC and a memory scrub engine to suppress soft errors. Unlike the VA41630, the VA41620 relies on external SPI NVM for non-volatile storage, providing design flexibility for applications requiring large external flash memories or custom boot configurations.
Connectivity options are extensive and tailored for space applications: three each of UART, I2C, and SPI interfaces, two CAN 2.0B buses, a 10/100 Ethernet MAC, a full-duplex SpaceWire interface, and 104 configurable GPIO pins. An 8-channel 12-bit ADC (600 ksps) and 2-channel 12-bit DAC support analog signal processing.
The VA41620 is fully spaceflight-qualified and available in 176-pin Ceramic QFP (CQFP), 176-pin Plastic QFP (PQFP), and 196-pin BGA packages.
