Markets and Applications

International Space Station

NINE HARDSIL© based die  are located on the STP-H5 (Space Test Program – Houston 5) assembly located on the International Space Station to measure effects of protons and cosmic rays. The system was created by Cosmiac in conjunction with NASA Johnson and AFRL (Air Force Research Laboratory) and consists of the VORAGO Technologies PA32KAS MCU, a stack of four 18Mb VORAGO Technologies SRAMs and four Texas Instruments 16Mb SRAM devices processed using HARDSIL© technology.

 

CubeSat

With support from NASA and partnering with Cosmiac, VORAGO Technologies have developed a stackable set of rad-hard CubeSat compatible compute modules using the VA10820 microcontroller. These boards are intended to allow rapid product development of picosatellites with a guaranteed-by-design rad-hard embedded processor at the heart of the system.

Any CubeSat developer that needs the security of a rad-hard MCU for reliability can download the ‘Radiation Hardened System Control Board for CubeSats’ Tech Brief here.

 

Satellites

VORAGO HARDSIL® technology is at the heart of two further upcoming missions, STPSat-5 and STPSat-6, both part of the Department of Defense’s Space Test Program (STP).

STPSat-5 is scheduled for late 2017 and will be in a Sun-synch orbit. The technological / scientific payload will further our understanding of this space environment. The STPSat-5 spacecraft build and integration is underway at Sierra Nevada Corporation and the launch vehicle will be Falcon-9 v1.2. The satellite is based upon SNC’s SN-50 Microsat architecture.

STPSat-6 is planned for late 2019 and will be in a Geosynchronous orbit. Several scientific payloads will be included on the satellite that is based upon Orbital ATK’s A500 bus, intended for a design life of 2 – 7 years.

In conjunction with AFRL (Air Force Research Laboratory) and Texas Instruments, VORAGO Technologies implemented HARDSIL® technology to radiation harden high-density SRAMs for space applications. VORAGO solved the major space radiation problems, Single Event Effects (SEEs), Total Ionizing Dose (TID) and Dose Rate by combining HARDSIL© process modifications and layout design innovations. These devices are used in the STP missions.

   

 

The VA10820 microcontroller is used in a next-generation X-ray telescope system as a system monitor and configuration solution. This is a popular use-case for the MCU, alongside an FPGA. This development by Penn State is an enhancement over the existing X-ray telescope used in NASA’s Swift mission.

A picture of the printed circuit board is shown below.

   

Aerospace & Defense

The U.S. Department of Defense – MDA (Missile Defense Agency) supported the development of and recognized VORAGO Technologies radiation hardened Dual-Port 8Mb SRAM as an MDA ‘Success Story’. The device was developed as a multi-purpose product with applicability in medical, aerospace and other high-reliability systems. The Missile Defense Agency interest in the product is for buffering high speed data between image sensors and processors in BMDS (Ballistic Missile Defense System) interceptors.
