HOLT expands its MIL-STD-1553 portfolio with its first Radiation Hardened MIL-STD-1553 Dual Transceiver for Hi-Rel applications such as launch vehicles and high-altitude aircraft.
Holt Integrated Circuits has announced the introduction of HI-1592, a radiation-hardened 3.3V MIL-STD-1553 dual transceiver for high reliability and space applications.
Holt has been a supplier of MIL-STD-1553 IP, protocol, transceiver and transformer components to the military and aerospace industries for over 20 years, and this new product offering provides additional robustness for demanding Hi-Rel applications such as launch vehicles, high-altitude aircraft, low-orbit satellites, and space.
As aircraft fly at higher altitudes or in space, they become more susceptible to exposure to cosmic rays, resulting in effects such as single-event transient (SET), single-event latch-up (SEL) and single-event burnout (SEB), any of which could result in degradation or failure of electronic equipment.
To that end, electronic equipment designed to fly in these environments needs some level of latch-up immunity or radiation hardness assurance (RHA) against the effects of cosmic rays.
Holt HI-1592 Key Features
- Robust Silicon-On-Insulator (SOI) CMOS technology
- RHA Total Ionising Dose (TID)
- 100 krad(Si) High Dose Rate
- Single-Event Effect (SEE) hardness
- SEB and SEL free up to 67.7 MeV-cm2/mg
- SET and SEFI characterised up to 67.7 MeV-cm2/mg
- MIL-PRF-38535 compliant
- 1.8V, 2.5V and 3.3V compatible digital I/O
- Extended temperature range with optional burn-in
The HI-1592 is latch-up immune and proven to meet a single-event upset (SEU) with an LET of at least 67.7 MeV-cm2/mg. The device is radiation tolerant to a total ionizing dose (TID) of 100 krad(Si).
It is ideal for launch vehicle and high-altitude aircraft applications utilising MIL-STD-1553 data bus communication.
The device also features 1.8V, 2.5V and 3.3V compatible digital I/O. This feature gives users more flexibility to interface with a broad range of FPGAs and controllers, avoiding the use of level shifters and other additional circuitry.
The HI-1592 is ideal for use with Holt’s DO-254 certifiable MIL-STD-1553 IP Core, HI-6300, instantiated in a radiation-hardened FPGA.
“High reliability and latch-up immunity are critical at higher altitudes, where aircraft are more susceptible to cosmic ray exposure and failure …. This new device will provide our customers with additional assurance that their product is robust and reliable in this harsh and demanding environment.”
George Noh | Director of Sales and Marketing at Holt Integrated Circuits
“The new Holt dual transceivers are a step forward for projects like geo satellites, offering longevity and protection against degradation and risk of failure in demanding environments and the problems they present. APC Technology Group is excited to introduce this innovative product to our customers, recognising its potential to revolutionise space-based applications.”
Richard Hough | Sales Director for High Reliability Components & Power Supplies at APC Technology Group
The HI-1592 is available in a hermetic 24-pin ceramic SOIC. The device is offered in an extended −55 °C to +125 °C temperature range, with the option of burn-in, 100% PIND testing and compliance to MIL-PRF-38535 QML class Q.
