Radiation & Reliability Data
Single Event Upset (SEU) and Single Event Latch-Up (SEL) Performance
Radiation Effects
Ionizing radiation can cause unwanted effects in semiconductor devices. Energetic protons, neutrons, heavy ions, and alpha particles can strike sensitive regions of the transistor, causing various failures, or Single Event Effects (SEE), such as:- Single Event Upsets (SEUs), which occur when high-energy ionizing particles, such as heavy ions, alpha particles or protons, irradiate a circuit or pass through an integrated circuit causing a disruption in the system logic.
- Single Event Latch-Up (SEL), which is a condition that causes loss of device functionality due to a single-event-induced high current state. A SEL may or may not cause permanent device damage, but requires power strobing of the device to resume normal device operations. Devices with low (< 37.5 MeV-cm2/mg) SEL LETth are considered unsuitable for space applications.
The SEU and SEL performance of Microsemi products are included in the radiation reports below. See also Conference Papers.

Total Ionizing Dose (TID)
Total Ionizing Dose (TID) is caused by radiation due to charged particles and gamma rays in Space. This radiation deposits energy by causing ionization in the material. The ionization can change the charge excitation, charge transport, bonding, and decomposition properties of the material, and therefore, the device parameters. Total dose is the cumulative ionizing radiation that an electronic device receives over a specified period of time. The damage is dependant on the amount of radiation and how long it took to accumulate the total dose and is expressed in RAD (Radiation Absorbed Dose). Microsemi performs wafer lot specific TID testing per TM1019 of Mil-Std 883 class B. Test reports are posted here for customers' information. The results obtained do not constitute a guarantee that all units from each wafer lot will meet the TID levels observed in sample testing.

Legacy
For over 20 years, Microsemi has delivered the most reliable field-programmable gate arrays (FPGAs) in the industry. Microsemi's high-reliability FPGAs have overall antifuse reliability ratings of less than 10 failures-in-time (FITs) and have a lifespan of more than 40 years. Microsemi FPGAs are production-proven, with more than 5 million devices shipped and more than 1 trillion antifuses manufactured. Microsemi devices are fully tested prior to shipment, with an outgoing defect level of only 122 ppm (further reliability data is available in the Microsemi Reliability Report). Additionally, the programmable architecture of these devices offers high performance, design flexibility, and fast and inexpensive prototyping-all without the expense of test vectors, NRE charges, long lead times, and schedule and cost penalties for design refinements.
Product Features
RT1020
The RT1020 device contains the same architecture as the A1020, A1020A, and A1020B devices. The architecture, a combinatorial logic module, is a logic structure with 8 inputs and 1 output. The logic itself is comprised of a 4-input MUX. In addition, since the RT1020 device contains the same number of gates and I/Os and has the same operating voltage as its commercial equivalent (A1020B), an inexpensive commercial grade A1020B-CQ84 device can be used during the prototype phase, and replaced by the RT1020 in the flight units.
RT1280
The RT1280A device uses the A1280A die from the ACT 2 family of FPGAs. It utilizes a 2-module architecture, consisting of combinatorial modules (C-modules) and sequential modules (S-modules) optimized for both combinatorial and sequential designs. Based on Microsemi's patented channeled array architecture, the RT1280A has 8,000 ASIC-equivalent gates and 140 user I/Os.
RT ACT 3
The RT1425A, RT1460A and RT14100A devices use the A1425A, A1460A and A14100A dies, respectively. These devices are derived from the ACT 3 family of FPGAs, which also utilizes the two-module channeled array architecture, and offers faster performance than the RT1280A. These devices also have fully pin- and function-compatible, commercially-equivalent devices for easy and inexpensive prototyping. The A1425A-CQ132C is used for the RT1425A, the A1460A-CQ196C is used for the RT1460A, and the A14100A-CQ256C is used for the RT14100A.

Radiation Survivability
Total dose results are summarized in two ways. The first method summarizes by the maximum total dose level that is reached when the parts fail to meet a device specification but remain functional. For Microsemi FPGAs, the parameter that exceeds the specification first is the standby supply current (ICC). The second method summarizes by the maximum total dose that is reached prior to the functional failure of the device. The Microsemi RT devices have varying total-dose radiation survivability. The ability of these devices to survive radiation effects is both device- and lot-dependent. You must evaluate and determine the applicability of these devices for specific design and environmental requirements. Typical results for the RT1020 device are ~100krads (Si) for standby ICC and >100 krads for functional failure. The RT1280A device has results from 4 to 10 krads (Si) for standby ICC, and 7 to 18 krads for functional failure. Typical results for ACT 3 devices are 10 to 28 krads for ICC, and 20 to 77 krads for functional failure. Microsemi will provide total dose radiation testing along with the test data on each pedigreed lot that is available for sale. This summary also shows single event upset (SEU) and single event latch-up testing that has been performed on Microsemi FPGAs.

Libero IDE enables users to integrate both schematic and HDL synthesis into a single flow and verify the entire design in a single environment.Prototyping
An inexpensive commercial grade A1020B-CQ84 device can be used during the prototype phase, and replaced by the RT1020 in the flight units. The RT1280A device is fully pin- and function-compatible with the commercially-equivalent A1280A-CQ172C device for easy, inexpensive prototyping. The RT ACT3 devices also have fully pin- and function-compatible, commercially-equivalent devices for easy and inexpensive prototyping. The A1425A-CQ132C is used for the RT1425A, the A1460A-CQ196C is used for the RT1460A, and the A14100A-CQ256C is used for the RT14100A.Programmers
